  Attributes

  `anchor` | Anchor location of this `Text` object.
  `angle` | Angle of the text box in degrees.
  `attached_map_index` | Index of the attached fieldmap or linemap.
  `box` | The frame and area around this `Text` object.
  `clipping` | `Clipping` properties of the `Text`

Text.anchor

  Anchor location of this `Text` object.

  Specify the anchor point, or fixed point, for the text object. As the text object grows or shrinks, the anchor location is fixed, while the rest of the box adjusts to accommodate the new size. (default = `TextAnchor.Left`)

  There are nine possible anchor position points, corresponding to the left, right, and center positions on the headline, midline, and baseline of the text box.

  Example showing how to set the anchor of a `Text` object:

      >>> text = frame.add_text('abc')
      >>> text.anchor = tecplot.constant.TextAnchor.Center

  See also

  `Text.position`

  Type:

    `TextAnchor`

Text.angle

  Angle of the text box in degrees.

  The text angle is the orientation of the text relative to the axis. The angle is measured in degrees counter-clockwise from horizontal. Horizontal text is at zero degrees; vertical text is at 90 degrees.

  Example showing how to set the angle of a `Text` object:

      >>> text = frame.add_text('abc')
      >>> text.angle = 45

  Type:

    `float` (degrees counter-clockwise)

Text.attached_map_index

  Index of the attached fieldmap or linemap.

  Example showing how to set the attached object `Index` of a `Text` object:

      >>> text = frame.add_text("abc")
      >>> text.attached_map_index = 1

  Type:

    `Index` or `None`

Text.box

  The frame and area around this `Text` object.

  > The text box is a rectangular frame drawn around the text. Note that in order to show the text box, you must set TextBox.type to a value other than `constant.TextBox.None_`.

  Example showing how to enable the text box for a `Text` object:

      >>> text = frame.add_text("abc")
      >>> text.box.type = tecplot.constant.TextBox.Filled

  Type:

    `annotation.TextBox`

Text.clipping

  `Clipping` properties of the `Text`

  Clipping refers to displaying only that portion of an object that falls within a specified clipping region of the plot. If you have specified your text position in the Frame coordinate system, the `Text` will be clipped to the frame. Default: `Clipping.ClipToViewport`.

  If you have specified the Grid coordinate system, you can choose to clip your `Text` to the frame or the viewport. The size of the viewport depends on the plot type as follows:

  > - 3D Cartesian - The viewport is the same as the frame, so viewport

  >     clipping is the same as frame clipping.

  > - 2D Cartesian/XY Line - The viewport is defined by the extents of

  >     the X and Y axes.

  > - Polar Line/Sketch - By default, the viewport is the same as the

  >     frame.

  Example showing how to set the clipping of a `Text`:

      >>> text = frame.add_text('abc')
      >>> text.clipping = tecplot.constant.Clipping.ClipToFrame

  Type:

    `Clipping`

Text.color

  `Color` of the `Text` object.

  Default: `Color.Black`. Example showing how to set the `Color` of a `Text` object:

      >>> text = frame.add_text("abc")
      >>> text.color = tecplot.constant.Color.Blue

  Type:

    `Color`

Text.font

  Typeface properties for a `Text` object.

  Example usage:

      >>> text = frame.add_text('abc')
      >>> text.font.typeface = 'Times'

  Type:

    `TextFont`

Text.line_spacing

  Spacing between lines in the text box.

  Line spacing is dependent on the height of the text and the size unit system in which it is drawn. This example shows how to set the line spacing of a `Text` object:

      >>> text = frame.add_text('abc')
      >>> text.line_spacing = 4

  Type:

    `float` (default = 1.0)

Text.position

  Anchor position of the `Text`.

  This is the position of the `Text` on the `Frame` and will be \((x,y)\) or \((\theta,r)\) depending on the plot type (Cartesian or polar). This example shows how to set the anchor position of a `Text` object:

      >>> text = frame.add_text("abc")
      >>> text.position = (1.0, 2.0)

  See also

  `Text.anchor`

  Type:

    `tuple`

Text.position_coordinate_system

  Position coordinate system of the `Text` object.

  The text object may be positioned using either the grid coordinate system or the frame coordinate system and must be one of `CoordSys.Frame` or `CoordSys.Grid`

  If the position_coordinate_system is `CoordSys.Frame`, then the size_units property must be `Units.Frame` or `Units.Point`.

  The text object’s position and text height are adjusted so that it remains identical to its visual appearance in the original coordinate and unit system.

  If the size units are `Units.Grid` and the position coordinate system is changed to `CoordSys.Frame`, then the size units will be changed to `Units.Frame`. (default = CoordSys.Frame)

  Example showing how to set the position coordinate system for a `Text` object:

      >>> from tecplot.constant import CoordSys
      >>> text = frame.add_text("abc")
      >>> text.position_coordinate_system = CoordSys.Grid

  Example showing side effect if size units are `CoordSys.Grid` and the coordinate system is changed to `CoordSys.Frame`:

      >>> from tecplot.constant import CoordSys, Units
      >>> text = frame.add_text("abc")
      >>> text.font.size_units = Units.Grid
      >>> text.position_coordinate_system = CoordSys.Frame
      >>> text.position_coordinate_system
      CoordSys.Frame
      >>> text.font.size_units
      Units.Frame

  Type:

    `CoordSys`

Text.scope

  The `Scope` (local or global) of the `Text`.

  Annotations with local scope are displayed only in the `frame` in which they are created. If the annotation is defined as having `global` scope, it will appear in all “like” `frames`. That is, those frames using the same data set as the one in which the annotation was created. (default: `Scope.Local`)

  Example showing how to set the scope of a `Text` object:

      >>> text = frame.add_text("abc")
      >>> text.scope = tecplot.constant.Scope.Global

  Type:

    `Scope`

Text.text_string

  The text to be displayed in a text box.

  You can embed Greek, Math, and User-defined characters into English-font strings by enclosing them with text formatting tags, together with the keyboard characters.

  The text formatting tags and their effects are as follows. Format tags are not case sensitive and may be either upper or lower case:

  > - <b>…</b> - Boldface

  > - <i>…</i> - Italic

  > - <verbatim>…</verbatim> - Verbatim

  > - <sub>…</sub> - Subscripts

  > - <sup>…</sup> - Superscripts

  > - <greek>…</greek> - Greek font.

  > - <math>…</math> - Math font.

  > - <userdef>…</userdef> - User-defined font.

  > - <helvetica>…</helvetica> - Helvetica font.

  > - <times>…</times> - Times font.

  > - <courier>…</courier> - Courier font.

  Not all fonts have Bold and/or Italic variants. For fonts that do not have these styles, the <b> and/or <i> tags may have no effect.

  Embedding and escaping special characters work only in English-font text; they have no effect in text created in Greek, Math, or User-defined character sets.

  You can produce subscripts or superscripts by enclosing any characters with <sub>…</sub> or <sup>…</sup>, respectively. Tecplot 360 has only one level of superscripts and subscripts. Expressions requiring additional levels must be created by hand using multiple text objects. If you alternate subscripts and superscripts, Tecplot 360 positions the superscript directly above the subscript. To produce consecutive superscripts, enclose all superscript characters in a single pair of tags.

  To insert a tag into text literally, precede the first angle bracket with a backslash (“”). To insert a backslash in the text, just type two backslashes (”"). This example shows how to set the text string of a `Text` object:

      >>> text = frame.add_text('abc')
      >>> text.text_string
      'abc'
      >>> text.text_string ='def'
      >>> text.text_string
      'def'

  Type:

    `str`

Text.type

  Normal or LaTeX text type setting.

  Possible values are `TextType.Regular` or `TextType.LaTeX`:

      >>> text = frame.add_text(r'\alpha')
      >>> text.type = TextType.LaTeX

  Type:

    `TextType`

      >>> text.box.fill_color = tecplot.constant.Color.Blue

  Type:

    `Color`

TextBox.line_thickness

  Border line thickness.

  Must be greater than 0, default: `0.1`. Example showing how to set the line thickness of the `text box`:

      >>> text = frame.add_text("abc")
      >>> text.box.line_thickness = 0.5

  Type:

    `float`

TextBox.margin

  Margin between the text and the surrounding border.

  Specify the margin as a percentage of the text character height. Margin must be greater than or equal to 0.0, and may be greater than 100. (default = 20.0)

  Example showing how to set the margin of the `text box` for a `Text` object:

      >>> text.font.italic = True

  Type:

    `bool`

TextFont.size

  The text size in the currently defined text size units.

  Example showing how to set the text size of a `Text` object:

      >>> text = frame.add_text('abc')
      >>> text.font.size_units = tecplot.constant.Units.Point
      >>> text.font.size = 14

  Type:

    `int`

TextFont.size_units

  Units of the text character height.

  `Units` may be one of the following:

  > - `Units.Point`: Specify character height in points.

  > - `Units.Frame`: Specify character height as a percentage of frame

  >     height

  > - `Units.Grid`: Specify character height in grid units.

  (default = `Units.Point`)

  Note

  - One point is 1/72nd of an inch.

  - `Units.Grid` is available only if position_coordinate_system is

      `CoordSys.Grid`

  - The position coordinate system will be changed to `CoordSys.Grid`

      if size units is set to `Units.Grid`

  Example showing how to set the units of the character height for a `Text` object:

      >>> from tecplot.constant import CoordSys
      >>> text = frame.add_text("abc")
      >>> text.position_coordinate_system = CoordSys.Grid
      >>> text.font.size_units = Units.Point

  Type:

    `Units`

TextFont.typeface

  The font family used by the `Text` object.

  For consistency across various platforms, Tecplot 360 guarantees that the following standard typeface names are available:

  > - “Helvetica”

  > - “Times”

  > - “Courier”

  > - “Greek”

  > - “Math”

  > - “User Defined”

  Other typefaces may or may not be available depending on the TrueType fonts available. If the typeface or style is not available, a suitable replacement will be selected. This example shows how to set the typeface of a `Text` object to ‘Times’:

      >>> text = frame.add_text('abc')
      >>> text.font.typeface = 'Times'

  Type:

    `str`

## Geometric Shapes

### Circle

class tecplot.annotation.Circle(uid, frame)

  A circle annotation attached to a `Frame`.

  See also

  `Frame.add_circle()`

      import tecplot as tp
      from tecplot.constant import *

      frame = tp.active_frame()

      circle0 = frame.add_circle((40, 50), 12, CoordSys.Frame)
      circle1 = frame.add_circle((50, 50), 12, CoordSys.Frame)
      circle2 = frame.add_circle((60, 50), 12, CoordSys.Frame)

      circle0.fill_color = Color.Magenta
      circle1.fill_color = Color.Yellow
      circle2.fill_color = Color.Cyan

      tp.export.save_png('circle.png', 600)

  Attributes

  `attached_map_index` | Index to the associated fieldmap or linemap.
  `clipping` | Clip geometry to the axes or frame for 2D plots.
  `color` | Line `Color`.
  `draw_order` | Draw before or after the data.
  `fill_color` | Background fill color.
  `line_pattern` | Pattern used for drawing lines or edges.
  `line_thickness` | Thickness of lines or edges.
  `macro_function` | An associated macro function.
  `num_points` | Number of points to use when creating the curved shape.

  `position_coordinate_system` | Position coordinate system.
  `radius` | Length of the radius.
  `scope` | Display annotation in all frames with the same data.
  `type` | The type of this annotation (read-only).

Circle.attached_map_index

  Index to the associated fieldmap or linemap.

  This property allows an annotation to follow the same active/inactive state as another plot object so their visibility can be changed together. Attach this annotation to a fieldmap or linemap using the object’s index property. Geometries and images that are attached to an inactive or non-existent zone are not displayed. Example usage assuming an annotation variable `anno`:

      >>> anno.attached_map_index = plot.fieldmap(2).index

  Type:

    `Index` or `None`

Circle.clipping

  Clip geometry to the axes or frame for 2D plots.

  Clipping refers to displaying only that portion of an object that falls within a specified clipping region of the plot. If you have specified the position in the Frame coordinate system, the Annotations will be clipped to the frame. Default: `Clipping.ClipToViewport`.

  If you have specified the Grid coordinate system, you can choose to clip your Annotations to the frame or the viewport. The size of the viewport depends on the plot type as follows:

  > - 3D Cartesian - The viewport is the same as the frame, so viewport

  >     clipping is the same as frame clipping.

  > - 2D Cartesian/XY Line - The viewport is defined by the extents of

  >     the X and Y axes.

  > - Polar Line/Sketch - By default, the viewport is the same as the

  >     frame.

  Warning

  For 3D and line plots the viewport is the same as the frame and so clipping to the viewport or the frame will have no apparent affect. In cartesian 2D plots, clipping to the axes (`Clipping.ClipToViewport`) is only available when the position coordinate system is `CoordSys.Grid`.

  Example of clipping a circle to the frame:

      >>> from tecplot.constant import Clipping, CoordSys
      >>> geom = frame.add_circle((0.5, 0.5), 0.55, CoordSys.Grid)
      >>> geom.clipping = Clipping.ClipToFrame

  Type:

    `Clipping`

Circle.color

  Line `Color`.

  This example shows how to change the edge or line `Color` to red:

      >>> from tecplot.constant import Color, CoordSys
      >>> geom = frame.add_circle((50, 50), 10, CoordSys.Frame)
      >>> geom.color = Color.Red

  Type:

    `Color`

Circle.draw_order

  Draw before or after the data.

  Annotations can be drawn either before or after the data. If a geometry or image is drawn before the data, the plot layers, such as mesh, contour lines, etc. will be drawn on top of the geometry. Otherwise, the annotation will be drawn last, potentially obscuring the data.

  Note

  Tecplot 360 draws all geometries and images first, in the order they were added, then all text.

  Example usage assuming an annotation variable `anno`:

      >>> from tecplot.constant import DrawOrder
      >>> anno.draw_order = DrawOrder.BeforeData

  Type:

    `constant.DrawOrder`

Circle.fill_color

  Background fill color.

  This example shows how to change the area fill `Color` to red. To turn off filling the geometry, set this attribute to `None`:

      >>> from tecplot.constant import Color, CoordSys
      >>> geom = frame.add_circle((50, 50), 10, CoordSys.Frame)
      >>> geom.fill_color = Color.Red

  Type:

    `constant.Color`

Circle.line_pattern

  Pattern used for drawing lines or edges.

  This example shows how to change the line pattern:

      >>> from tecplot.constant import CoordSys, LinePattern
      >>> geom = frame.add_circle((50, 50), 10, CoordSys.Frame)
      >>> geom.line_pattern = LinePattern.DashDot

  Type:

    `LinePattern`

Circle.line_thickness

  Thickness of lines or edges.

  This example shows how to change the line thickness:

      >>> from tecplot.constant import CoordSys
      >>> geom = frame.add_circle((50, 50), 10, CoordSys.Frame)
      >>> geom.line_thickness = 4.0

  Type:

    `float`

Circle.macro_function

  An associated macro function.

  All geometry or image annotations may be linked to a macro function. This macro function is called when you hold down the Control key (Command key on Mac OS X) and click the right mouse button on the text, geometry or image in the frame.

  In order to be attached to a text or geometry object, the macro function must be a “retained” macro function. A macro function is “retained” via either of the following scenarios:

  - running a macro file that contains the required macro functions

  - including it in your tecplot.mcr file (which is run at start up, making it a special case of the preceding scenario)

  In both cases, the macro function is defined using the $!MACROFUNCTION macro command. Refer to “$!MACROFUNCTION…$!ENDMACROFUNCTION” on page 157 in the Tecplot Macro Scripting Guide for additional information.

  Example usage assuming an annotation variable `anno`:

      >>> anno.macro_function = 'MYMACROFUNCTION'

  To run this function from PyTecplot it is neccessary to pass the function to a call to `macro.execute_function()`:

      >>> tecplot.macro.execute_function(anno.macro_function)

  Type:

    `str`

Circle.num_points

  Number of points to use when creating the curved shape.

  This is the number of segments along the edge plus one. Example usage:

      >>> from tecplot.constant import CoordSys
      >>> geom = frame.add_circle((50, 50), 10, CoordSys.Frame)
      >>> geom.num_points = 300

  Type:

    `int`

Circle.pattern_length

  Length of the line pattern.

  This example shows how to change the pattern length:

      >>> from tecplot.constant import CoordSys
      >>> geom = frame.add_circle((50, 50), 10, CoordSys.Frame)
      >>> geom.pattern_length = 1.2

  Type:

    `float`

Circle.position

  Location on the `Frame`.

  This is the origin of the annotation and will be \((x,y)\) or \((\theta,r)\) depending on the plot type. Example usage assuming an annotation variable `anno`:

      >>> anno.position = (3, 4)

  Type:

    `tuple`

Circle.position_coordinate_system

  Position coordinate system.

  The object may be positioned using either the grid coordinate system or the frame coordinate system and must be one of `CoordSys.Frame` or `CoordSys.Grid`:

  > - `CoordSys.Frame`: The geometry is always displayed at constant size and position when you zoom in or out of the plot.

  > - `CoordSys.Grid`: The geometry resizes and moves with the data grid. However, the geometry remains fixed when you rotate the plot. Changing the center of rotation may cause the geometry to move.

  Example usage assuming an annotation variable `anno`:

      >>> from tecplot.constant import CoordSys
      >>> anno.position_coordinate_system = CoordSys.Frame

  Type:

    `CoordSys`

Circle.radius

  Length of the radius.

  This will be in the coordinate system specified by `Circle.position_coordinate_system`. This example creates a circle of radius 5 and then doubles it to 10 later:

      >>> from tecplot.constant import CoordSys
      >>> geom = frame.add_circle((20, 30), 5, CoordSys.Frame)
      >>> geom.radius = 10

  Type:

    `float`

Circle.scope

  Display annotation in all frames with the same data.

  Annotations with local scope are displayed only in the `Frame` in which they are created. If it is defined as having `global` scope, it will appear in all “like” `frames`. That is, those frames using the same data set as the one in which the annotation was created. (default: `Scope.Local`)

  Example usage assuming an annotation variable `anno`:

      >>> from tecplot.constant import Scope
      >>> anno.scope = Scope.Global

  Type:

    `Scope`

Circle.type

  The type of this annotation (read-only).

  This is the generic type information for geometry and image annotations. This is a read-only parameter and is used, in combination with position_coordinate_system to determine the actual return types of the iterators `Frame.geometries()` and `Frame.images()`:

      >>> frame.add_image('image.png', (1, 1), 5)
      >>> frame.add_circle((0,0), 1, CoordSys.Grid)
      >>> frame.add_square((0,0), 1, CoordSys.Grid)
      >>> for anno in frame.images():
      ...     print(anno.type)
      ...
      GeomType.Image
      >>> for anno in frame.geometries():
      ...     print(anno.type)
      ...
      GeomType.Circle
      GeomType.Square

  Type:

    `GeomType`

### Ellipse

class tecplot.annotation.Ellipse(uid, frame)

  An ellipse annotation attached to a `Frame`.

  See also

  `Frame.add_ellipse()`

      import tecplot as tp
      from tecplot.constant import *

      frame = tp.active_frame()

      ellipse0 = frame.add_ellipse((40, 45), (10, 12), CoordSys.Frame)
      ellipse1 = frame.add_ellipse((50, 50), (10, 16), CoordSys.Frame)
      ellipse2 = frame.add_ellipse((60, 55), (10, 20), CoordSys.Frame)

      ellipse0.fill_color = Color.Magenta
      ellipse1.fill_color = Color.Yellow
      ellipse2.fill_color = Color.Cyan

      tp.export.save_png('ellipse.png', 600)

Ellipse.attached_map_index

  Index to the associated fieldmap or linemap.

  This property allows an annotation to follow the same active/inactive state as another plot object so their visibility can be changed together. Attach this annotation to a fieldmap or linemap using the object’s index property. Geometries and images that are attached to an inactive or non-existent zone are not displayed. Example usage assuming an annotation variable `anno`:

      >>> anno.attached_map_index = plot.fieldmap(2).index

  Type:

    `Index` or `None`

Ellipse.clipping

  Clip geometry to the axes or frame for 2D plots.

  Clipping refers to displaying only that portion of an object that falls within a specified clipping region of the plot. If you have specified the position in the Frame coordinate system, the Annotations will be clipped to the frame. Default: `Clipping.ClipToViewport`.

  If you have specified the Grid coordinate system, you can choose to clip your Annotations to the frame or the viewport. The size of the viewport depends on the plot type as follows:

  > - 3D Cartesian - The viewport is the same as the frame, so viewport

  >     clipping is the same as frame clipping.

  > - 2D Cartesian/XY Line - The viewport is defined by the extents of

  >     the X and Y axes.

  > - Polar Line/Sketch - By default, the viewport is the same as the

  >     frame.

  Warning

  For 3D and line plots the viewport is the same as the frame and so clipping to the viewport or the frame will have no apparent affect. In cartesian 2D plots, clipping to the axes (`Clipping.ClipToViewport`) is only available when the position coordinate system is `CoordSys.Grid`.

  Example of clipping a circle to the frame:

      >>> from tecplot.constant import Clipping, CoordSys
      >>> geom = frame.add_circle((0.5, 0.5), 0.55, CoordSys.Grid)
      >>> geom.clipping = Clipping.ClipToFrame

  Type:

    `Clipping`

Ellipse.color

  Line `Color`.

  This example shows how to change the edge or line `Color` to red:

      >>> from tecplot.constant import Color, CoordSys
      >>> geom = frame.add_circle((50, 50), 10, CoordSys.Frame)
      >>> geom.color = Color.Red

  Type:

    `Color`

Ellipse.draw_order

  Draw before or after the data.

  Annotations can be drawn either before or after the data. If a geometry or image is drawn before the data, the plot layers, such as mesh, contour lines, etc. will be drawn on top of the geometry. Otherwise, the annotation will be drawn last, potentially obscuring the data.

  Note

  Tecplot 360 draws all geometries and images first, in the order they were added, then all text.

  Example usage assuming an annotation variable `anno`:

      >>> from tecplot.constant import DrawOrder
      >>> anno.draw_order = DrawOrder.BeforeData

  Type:

    `constant.DrawOrder`

Ellipse.fill_color

  Background fill color.

  This example shows how to change the area fill `Color` to red. To turn off filling the geometry, set this attribute to `None`:

      >>> from tecplot.constant import Color, CoordSys
      >>> geom = frame.add_circle((50, 50), 10, CoordSys.Frame)
      >>> geom.fill_color = Color.Red

  Type:

    `constant.Color`

Ellipse.line_pattern

  Pattern used for drawing lines or edges.

  This example shows how to change the line pattern:

      >>> from tecplot.constant import CoordSys, LinePattern
      >>> geom = frame.add_circle((50, 50), 10, CoordSys.Frame)
      >>> geom.line_pattern = LinePattern.DashDot

  Type:

    `LinePattern`

Ellipse.line_thickness

  Thickness of lines or edges.

  This example shows how to change the line thickness:

      >>> from tecplot.constant import CoordSys
      >>> geom = frame.add_circle((50, 50), 10, CoordSys.Frame)
      >>> geom.line_thickness = 4.0

  Type:

    `float`

Ellipse.macro_function

  An associated macro function.

  All geometry or image annotations may be linked to a macro function. This macro function is called when you hold down the Control key (Command key on Mac OS X) and click the right mouse button on the text, geometry or image in the frame.

  In order to be attached to a text or geometry object, the macro function must be a “retained” macro function. A macro function is “retained” via either of the following scenarios:

  - running a macro file that contains the required macro functions

  - including it in your tecplot.mcr file (which is run at start up, making it a special case of the preceding scenario)

  In both cases, the macro function is defined using the $!MACROFUNCTION macro command. Refer to “$!MACROFUNCTION…$!ENDMACROFUNCTION” on page 157 in the Tecplot Macro Scripting Guide for additional information.

  Example usage assuming an annotation variable `anno`:

      >>> anno.macro_function = 'MYMACROFUNCTION'

  To run this function from PyTecplot it is neccessary to pass the function to a call to `macro.execute_function()`:

      >>> tecplot.macro.execute_function(anno.macro_function)

  Type:

    `str`

Ellipse.num_points

  Number of points to use when creating the curved shape.

  This is the number of segments along the edge plus one. Example usage:

      >>> from tecplot.constant import CoordSys

      >>> geom.num_points = 300

  Type:

    `int`

Ellipse.pattern_length

      >>> geom.pattern_length = 1.2

  Type:

    `float`

Ellipse.position

  Location on the `Frame`.

  This is the origin of the annotation and will be \((x,y)\) or \((\theta,r)\) depending on the plot type. Example usage assuming an annotation variable `anno`:

      >>> anno.position = (3, 4)

  Type:

    `tuple`

Ellipse.position_coordinate_system

  Position coordinate system.

  The object may be positioned using either the grid coordinate system or the frame coordinate system and must be one of `CoordSys.Frame` or `CoordSys.Grid`:

  > - `CoordSys.Frame`: The geometry is always displayed at constant size and position when you zoom in or out of the plot.

  > - `CoordSys.Grid`: The geometry resizes and moves with the data grid. However, the geometry remains fixed when you rotate the plot. Changing the center of rotation may cause the geometry to move.

  Example usage assuming an annotation variable `anno`:

      >>> from tecplot.constant import CoordSys
      >>> anno.position_coordinate_system = CoordSys.Frame

  Type:

    `CoordSys`

Ellipse.scope

  Display annotation in all frames with the same data.

  Annotations with local scope are displayed only in the `Frame` in which they are created. If it is defined as having `global` scope, it will appear in all “like” `frames`. That is, those frames using the same data set as the one in which the annotation was created. (default: `Scope.Local`)

  Example usage assuming an annotation variable `anno`:

      >>> from tecplot.constant import Scope
      >>> anno.scope = Scope.Global

  Type:

    `Scope`

Ellipse.size

  Size \((h_{axis}, v_{axis})\) of the ellipse.

  This is the horizontal and vertical axis lengths of the ellipse and will be in the coordinate system specified by `Ellipse.position_coordinate_system`. This example creates an ellipse with \((h_{axis}, v_{axis})\) of \((5, 10)\) and changes it to \((10, 20)\) later:

      >>> from tecplot.constant import CoordSys
      >>> geom = frame.add_ellipse((50, 50), (5, 10), CoordSys.Frame)
      >>> geom.size = (10, 20)

  Type:

    `tuple`

Ellipse.type

  The type of this annotation (read-only).

  This is the generic type information for geometry and image annotations. This is a read-only parameter and is used, in combination with position_coordinate_system to determine the actual return types of the iterators `Frame.geometries()` and `Frame.images()`:

      >>> frame.add_image('image.png', (1, 1), 5)
      >>> frame.add_circle((0,0), 1, CoordSys.Grid)
      >>> frame.add_square((0,0), 1, CoordSys.Grid)
      >>> for anno in frame.images():
      ...     print(anno.type)
      ...
      GeomType.Image
      >>> for anno in frame.geometries():
      ...     print(anno.type)

  Annotations with local scope are displayed only in the `Frame` in which they are created. If it is defined as having `global` scope, it will appear in all “like” `frames`. That is, those frames using the same data set as the one in which the annotation was created. (default: `Scope.Local`)

  Example usage assuming an annotation variable `anno`:

      >>> from tecplot.constant import Scope
      >>> anno.scope = Scope.Global

  Type:

    `Scope`

Square.size

  Length of one side of the square.

  This will be in the coordinate system specified by `Square.position_coordinate_system`. This example creates a square of side-length 5 and then doubles it to 10 later:

      >>> from tecplot.constant import CoordSys
      >>> geom = frame.add_square((50, 50), 5, CoordSys.Frame)
      >>> geom.radius = 10

  Type:

    `float`

Square.type

  The type of this annotation (read-only).

  This is the generic type information for geometry and image annotations. This is a read-only parameter and is used, in combination with position_coordinate_system to determine the actual return types of the iterators `Frame.geometries()` and `Frame.images()`:

      >>> frame.add_image('image.png', (1, 1), 5)
      >>> frame.add_circle((0,0), 1, CoordSys.Grid)
      >>> frame.add_square((0,0), 1, CoordSys.Grid)
      >>> for anno in frame.images():
      ...     print(anno.type)
      ...
      GeomType.Image
      >>> for anno in frame.geometries():
      ...     print(anno.type)
      ...
      GeomType.Circle
      GeomType.Square

  Type:

  Attributes

  `arrowhead` | Style control for arrowheads.
  `attached_map_index` | Index to the associated fieldmap or linemap.
  `clipping` | Clip geometry to the axes or frame for 2D plots.
  `color` | Line `Color`.
  `draw_order` | Draw before or after the data.
  `fill_color` | Background fill color.
  `line_pattern` | Pattern used for drawing lines or edges.
  `line_thickness` | Thickness of lines or edges.
  `macro_function` | An associated macro function.

Polyline2D.arrowhead

  Style control for arrowheads.

  Example usage:

      >>> from tecplot.constant import ArrowheadAttachment, ArrowheadStyle
      >>> polyline.arrowhead.attachment = ArrowheadAttachment.AtEnd
      >>> polyline.arrowhead.style = ArrowheadStyle.Filled

  Type:

    `Arrowhead`

Polyline2D.attached_map_index

  Index to the associated fieldmap or linemap.

  This property allows an annotation to follow the same active/inactive state as another plot object so their visibility can be changed together. Attach this annotation to a fieldmap or linemap using the object’s index property. Geometries and images that are attached to an inactive or non-existent zone are not displayed. Example usage assuming an annotation variable `anno`:

      >>> anno.attached_map_index = plot.fieldmap(2).index

  Type:

    `Index` or `None`

Polyline2D.clipping

  Clip geometry to the axes or frame for 2D plots.

  Clipping refers to displaying only that portion of an object that falls within a specified clipping region of the plot. If you have specified the position in the Frame coordinate system, the Annotations will be clipped to the frame. Default: `Clipping.ClipToViewport`.

  If you have specified the Grid coordinate system, you can choose to clip your Annotations to the frame or the viewport. The size of the viewport depends on the plot type as follows:

  > - 3D Cartesian - The viewport is the same as the frame, so viewport

  >     clipping is the same as frame clipping.

  > - 2D Cartesian/XY Line - The viewport is defined by the extents of

  >     the X and Y axes.

  > - Polar Line/Sketch - By default, the viewport is the same as the

  >     frame.

  Warning

  For 3D and line plots the viewport is the same as the frame and so clipping to the viewport or the frame will have no apparent affect. In cartesian 2D plots, clipping to the axes (`Clipping.ClipToViewport`) is only available when the position coordinate system is `CoordSys.Grid`.

  Example of clipping a circle to the frame:

      >>> from tecplot.constant import Clipping, CoordSys
      >>> geom = frame.add_circle((0.5, 0.5), 0.55, CoordSys.Grid)
      >>> geom.clipping = Clipping.ClipToFrame

  Type:

    `Clipping`

Polyline2D.color

  Line `Color`.

  This example shows how to change the edge or line `Color` to red:

      >>> from tecplot.constant import Color, CoordSys
      >>> geom = frame.add_circle((50, 50), 10, CoordSys.Frame)
      >>> geom.color = Color.Red

  Type:

    `Color`

Polyline2D.draw_order

  Draw before or after the data.

  Annotations can be drawn either before or after the data. If a geometry or image is drawn before the data, the plot layers, such as mesh, contour lines, etc. will be drawn on top of the geometry. Otherwise, the annotation will be drawn last, potentially obscuring the data.

  Note

  Tecplot 360 draws all geometries and images first, in the order they were added, then all text.

  Example usage assuming an annotation variable `anno`:

      >>> from tecplot.constant import DrawOrder
      >>> anno.draw_order = DrawOrder.BeforeData

  Type:

    `constant.DrawOrder`

Polyline2D.fill_color

  Background fill color.

  This example shows how to change the area fill `Color` to red. To turn off filling the geometry, set this attribute to `None`:

      >>> from tecplot.constant import Color, CoordSys
      >>> geom = frame.add_circle((50, 50), 10, CoordSys.Frame)
      >>> geom.fill_color = Color.Red

  Type:

    `constant.Color`

Polyline2D.line_pattern

  Pattern used for drawing lines or edges.

  This example shows how to change the line pattern:

      >>> geom.line_pattern = LinePattern.DashDot

  Type:

    `LinePattern`

Polyline2D.line_thickness

  Thickness of lines or edges.

  This example shows how to change the line thickness:

      >>> from tecplot.constant import CoordSys
      >>> geom = frame.add_circle((50, 50), 10, CoordSys.Frame)
      >>> geom.line_thickness = 4.0

  Type:

    `float`

Polyline2D.macro_function

  An associated macro function.

  All geometry or image annotations may be linked to a macro function. This macro function is called when you hold down the Control key (Command key on Mac OS X) and click the right mouse button on the text, geometry or image in the frame.

  In order to be attached to a text or geometry object, the macro function must be a “retained” macro function. A macro function is “retained” via either of the following scenarios:

  - running a macro file that contains the required macro functions

  - including it in your tecplot.mcr file (which is run at start up, making it a special case of the preceding scenario)

  In both cases, the macro function is defined using the $!MACROFUNCTION macro command. Refer to “$!MACROFUNCTION…$!ENDMACROFUNCTION” on page 157 in the Tecplot Macro Scripting Guide for additional information.

  Example usage assuming an annotation variable `anno`:

      >>> anno.macro_function = 'MYMACROFUNCTION'

  To run this function from PyTecplot it is neccessary to pass the function to a call to `macro.execute_function()`:

      >>> tecplot.macro.execute_function(anno.macro_function)

  Type:

    `str`

Polyline2D.pattern_length

  This example shows how to change the pattern length:

      >>> from tecplot.constant import CoordSys
      >>> geom = frame.add_circle((50, 50), 10, CoordSys.Frame)
      >>> geom.pattern_length = 1.2

  Type:

    `float`

Polyline2D.position

  Location on the `Frame`.

  This is the origin of the annotation and will be \((x,y)\) or \((\theta,r)\) depending on the plot type. Example usage assuming an annotation variable `anno`:

      >>> anno.position = (3, 4)

  Type:

    `tuple`

Polyline2D.position_coordinate_system

  Position coordinate system.

  The object may be positioned using either the grid coordinate system or the frame coordinate system and must be one of `CoordSys.Frame` or `CoordSys.Grid`:

  > - `CoordSys.Frame`: The geometry is always displayed at constant size and position when you zoom in or out of the plot.

  > - `CoordSys.Grid`: The geometry resizes and moves with the data grid. However, the geometry remains fixed when you rotate the plot. Changing the center of rotation may cause the geometry to move.

  Example usage assuming an annotation variable `anno`:

      >>> from tecplot.constant import CoordSys
      >>> anno.position_coordinate_system = CoordSys.Frame

  Type:

    `CoordSys`

      >>> frame.add_image('image.png', (1, 1), 5)
      >>> frame.add_circle((0,0), 1, CoordSys.Grid)
      >>> frame.add_square((0,0), 1, CoordSys.Grid)

  Type:

    `Arrowhead`

MultiPolyline2D.attached_map_index

  Index to the associated fieldmap or linemap.

  This property allows an annotation to follow the same active/inactive state as another plot object so their visibility can be changed together. Attach this annotation to a fieldmap or linemap using the object’s index property. Geometries and images that are attached to an inactive or non-existent zone are not displayed.

MultiPolyline2D.clipping

  Clip geometry to the axes or frame for 2D plots.

  Clipping refers to displaying only that portion of an object that falls within a specified clipping region of the plot. If you have specified the position in the Frame coordinate system, the Annotations will be clipped to the frame. Default: `Clipping.ClipToViewport`.

  If you have specified the Grid coordinate system, you can choose to clip your Annotations to the frame or the viewport. The size of the viewport depends on the plot type as follows:

  > - 3D Cartesian - The viewport is the same as the frame, so viewport

  >     clipping is the same as frame clipping.

  > - 2D Cartesian/XY Line - The viewport is defined by the extents of

  >     the X and Y axes.

  > - Polar Line/Sketch - By default, the viewport is the same as the

  >     frame.

  Warning

  For 3D and line plots the viewport is the same as the frame and so clipping to the viewport or the frame will have no apparent affect. In cartesian 2D plots, clipping to the axes (`Clipping.ClipToViewport`) is only available when the position coordinate system is `CoordSys.Grid`.

  Example of clipping a circle to the frame:

      >>> from tecplot.constant import Clipping, CoordSys
      >>> geom = frame.add_circle((0.5, 0.5), 0.55, CoordSys.Grid)

  Annotations can be drawn either before or after the data. If a geometry or image is drawn before the data, the plot layers, such as mesh, contour lines, etc. will be drawn on top of the geometry. Otherwise, the annotation will be drawn last, potentially obscuring the data.

  Note

  Tecplot 360 draws all geometries and images first, in the order they were added, then all text.

  Example usage assuming an annotation variable `anno`:

      >>> from tecplot.constant import DrawOrder
      >>> anno.draw_order = DrawOrder.BeforeData

  This is the origin of the annotation and will be \((x,y)\) or \((\theta,r)\) depending on the plot type. Example usage assuming an annotation variable `anno`:

      >>> anno.position = (3, 4)

  Type:

    `tuple`

MultiPolyline2D.position_coordinate_system

  Position coordinate system.

  The object may be positioned using either the grid coordinate system or the frame coordinate system and must be one of `CoordSys.Frame` or `CoordSys.Grid`:

  > - `CoordSys.Frame`: The geometry is always displayed at constant size and position when you zoom in or out of the plot.

  > - `CoordSys.Grid`: The geometry resizes and moves with the data grid. However, the geometry remains fixed when you rotate the plot. Changing the center of rotation may cause the geometry to move.

MultiPolyline3D.attached_map_index

  Index to the associated fieldmap or linemap.

  This property allows an annotation to follow the same active/inactive state as another plot object so their visibility can be changed together. Attach this annotation to a fieldmap or linemap using the object’s index property. Geometries and images that are attached to an inactive or non-existent zone are not displayed. Example usage assuming an annotation variable `anno`:

      >>> anno.attached_map_index = plot.fieldmap(2).index

      >>> geom.color = Color.Red

  Type:

    `Color`

MultiPolyline3D.fill_color

MultiPolyline3D.macro_function

  An associated macro function.

  All geometry or image annotations may be linked to a macro function. This macro function is called when you hold down the Control key (Command key on Mac OS X) and click the right mouse button on the text, geometry or image in the frame.

  In order to be attached to a text or geometry object, the macro function must be a “retained” macro function. A macro function is “retained” via either of the following scenarios:

  - running a macro file that contains the required macro functions

  - including it in your tecplot.mcr file (which is run at start up, making it a special case of the preceding scenario)

  In both cases, the macro function is defined using the $!MACROFUNCTION macro command. Refer to “$!MACROFUNCTION…$!ENDMACROFUNCTION” on page 157 in the Tecplot Macro Scripting Guide for additional information.

  Example usage assuming an annotation variable `anno`:

      >>> anno.macro_function = 'MYMACROFUNCTION'

  Annotations with local scope are displayed only in the `Frame` in which they are created. If it is defined as having `global` scope, it will appear in all “like” `frames`. That is, those frames using the same data set as the one in which the annotation was created. (default: `Scope.Local`)

  Example usage assuming an annotation variable `anno`:

      >>> from tecplot.constant import Scope
      >>> anno.scope = Scope.Global

  Type:

    `Scope`

MultiPolyline3D.type

  The type of this annotation (read-only).

Image.attached_map_index

  Index to the associated fieldmap or linemap.

  This property allows an annotation to follow the same active/inactive state as another plot object so their visibility can be changed together. Attach this annotation to a fieldmap or linemap using the object’s index property. Geometries and images that are attached to an inactive or non-existent zone are not displayed.

  Type:

    `Index` or `None`

Image.draw_order

      >>> image.height = 40

  Type:

    `float`

Image.macro_function

  An associated macro function.

  All geometry or image annotations may be linked to a macro function. This macro function is called when you hold down the Control key (Command key on Mac OS X) and click the right mouse button on the text, geometry or image in the frame.

  - running a macro file that contains the required macro functions

  - including it in your tecplot.mcr file (which is run at start up, making it a special case of the preceding scenario)

  In both cases, the macro function is defined using the $!MACROFUNCTION macro command. Refer to “$!MACROFUNCTION…$!ENDMACROFUNCTION” on page 157 in the Tecplot Macro Scripting Guide for additional information.

  Example usage assuming an annotation variable `anno`:

      >>> anno.macro_function = 'MYMACROFUNCTION'

  Type:

    \((width, height)\)

Image.type

  The type of this annotation (read-only).
