      tp.export.save_png('axes_2d.png', 600, supersample=3)

  Attributes

  `auto_adjust_ranges` | Automatically adjust axis ranges to nice values.
  `axis_mode` | Controls automatic adjustment of axis ranges.
  `grid_area` | Area bounded by the axes.
  `precise_grid` | Precise dot grid.
  `preserve_scale` | Preserve scale (spacing between ticks) on range change.
  `viewport` | Area of the frame used by the plot axes.

`Cartesian2DFieldAxes.``auto_adjust_ranges`

  Automatically adjust axis ranges to nice values.

  Axes limits will be adjusted to have the smallest number of significant digits possible:

      >>> plot.axes.auto_adjust_ranges = False

  Type

    `bool`

`Cartesian2DFieldAxes.``axis_mode`

  Controls automatic adjustment of axis ranges.

  Possible values: `Independent`, `XYDependent`.

  If set to `XYDependent`, then setting the range of one axis automatically scales the other indicated axes proportionally to maintain the aspect ratio of the plot, effectively zooming in or out. If set to `Independent`, adjusting the range of one axis has no effect on other axes. Defaults to `Independent` for XY line plots, `XYDependent` for 2D Cartesian plots. Example usage:

      >>> from tecplot.constant import AxisMode
      >>> plot.axes.axis_mode = AxisMode.Independent

  Type

    `AxisMode`

`Cartesian2DFieldAxes.``grid_area`

  Area bounded by the axes.

  This controls the background color and border of the axes:

      >>> from tecplot.constant import Color
      >>> plot.axes.grid_area.fill_color = Color.LightGreen

  Type

    `GridArea`

`Cartesian2DFieldAxes.``precise_grid`

  Precise dot grid.

  This is a set of small dots drawn at the intersection of every minor gridline. In line plots, the axis assignments for the first active mapping govern the precise dot grid. The precise dot grid option is disabled for the 3D Cartesian plots and Line plots when either axis for the first active line mapping uses a log scale:

      >>> plot.axes.precise_grid.show = True

  Type

    `PreciseGrid`

`Cartesian2DFieldAxes.``preserve_scale`

  Preserve scale (spacing between ticks) on range change.

  This maintains the axis scaling, i.e. the distance between values along the axis. If `False`, the axes length will be preserved when the range changes:

      >>> plot.axes.preserve_scale = False
      >>> # get axis via "plot.axes.x_axis(0)" for line plots
      >>> # or "plot.axes.x_axis" for field or sketch plots
      >>> axis.max = 10 # axis scale is changed (length is preserved)

  Type

    `bool`

`Cartesian2DFieldAxes.``viewport`

  Area of the frame used by the plot axes.

  Example usage:

      >>> plot.axes.viewport.left = 5
      >>> plot.axes.viewport.right = 95
      >>> plot.axes.viewport.top = 95
      >>> plot.axes.viewport.bottom = 5

  Type

      >>> plot.axes.x_axis.show = False

  Type

    `Cartesian2DFieldAxis`

`Cartesian2DFieldAxes.``xy_ratio`

  X:Y axis scaling ratio in percent.

  This requires the axes to be in dependent mode:

      >>> from tecplot.constant import AxisMode
      >>> plot.axes.axis_mode = AxisMode.XYDependent
      >>> plot.axes.xy_ratio = 2

  Type

    `float`

  Y-axis style control.

  Example usage:

      >>> plot.axes.y_axis.show = False

  Type

    `Cartesian2DFieldAxis`

`Cartesian2DFieldAxis.``adjust_range_to_nice`()

  Rounds the axis range to the nearest major axis increment.

  This method resets the axis-line label values such that all currently displayed label values are set to have the smallest number of significant digits possible.

  Example usage:

      >>> # get axis via "plot.axes.x_axis(0)" for line plots
      >>> # or "plot.axes.x_axis" for field or sketch plots
      >>> axis.adjust_range_to_nice()

`Cartesian2DFieldAxis.``fit_range`(consider_blanking=True)

  Set range of axis to variable minimum and maximum.

  Note

  If the axis dependency is not `Independent`, then this action may also affect the range on another axis.

  Parameters

    consider_blanking (`Boolean`, optional) – If `True` and blanking is enabled, the resulting view excludes blanked cells at the edges of the plot. If `False`, then the resulting view will ignore blanked cells at the edges of the plot. (default: `True`)

  Example usage:

      >>> # get axis via "plot.axes.x_axis(0)" for line plots
      >>> # or "plot.axes.x_axis" for field or sketch plots

`Cartesian2DFieldAxis.``fit_range_to_nice`(consider_blanking=True)

  Set range of axis to nice values near variable minimum and maximum.

  This method resets the range to equal the minimum and maximum of the data being plotted, but makes the axis values “nice” by setting labels to have the smallest number of significant digits possible,

  Note

  If the axis dependency is not independent then this method may also affect the range on another axis.

  Parameters

      >>> plot.axes.reset_scale()

  Type

    `float`

`Cartesian3DFieldAxes.``aspect_ratio_reset`

  If set to `XYDependent` or `XYZDependent`, then setting the range of one axis automatically scales the other indicated axes proportionally to maintain the aspect ratio of the plot, effectively zooming in or out. If set to `Independent`, adjusting the range of one axis has no effect on other axes. Defaults to `XYZDependent` for 3D Cartesian plots. Both dependent modes allow specifying the axes scaling ratios:

      >>> from tecplot.constant import AxisMode

      >>> # get axis via "plot.axes.x_axis(0)" for line plots
      >>> # or "plot.axes.x_axis" for field or sketch plots

`Cartesian3DFieldAxis.``adjust_range_to_nice`()

  Rounds the axis range to the nearest major axis increment.

  This method resets the axis-line label values such that all currently displayed label values are set to have the smallest number of significant digits possible.

  Example usage:

      >>> # get axis via "plot.axes.x_axis(0)" for line plots
      >>> # or "plot.axes.x_axis" for field or sketch plots
      >>> axis.adjust_range_to_nice()

`Cartesian3DFieldAxis.``fit_range`(consider_blanking=True)

  Set range of axis to variable minimum and maximum.

  Note

  If the axis dependency is not `Independent`, then this action may also affect the range on another axis.

  Parameters

    consider_blanking (`Boolean`, optional) – If `True` and blanking is enabled, the resulting view excludes blanked cells at the edges of the plot. If `False`, then the resulting view will ignore blanked cells at the edges of the plot. (default: `True`)

  Example usage:

      >>> # get axis via "plot.axes.x_axis(0)" for line plots
      >>> # or "plot.axes.x_axis" for field or sketch plots
      >>> axis.fit_range()

`Cartesian3DFieldAxis.``fit_range_to_nice`(consider_blanking=True)

  Set range of axis to nice values near variable minimum and maximum.

  This method resets the range to equal the minimum and maximum of the data being plotted, but makes the axis values “nice” by setting labels to have the smallest number of significant digits possible,

  Note

  If the axis dependency is not independent then this method may also affect the range on another axis.

  Parameters

### XYLineAxes

class `tecplot.plot.``XYLineAxes`(plot)

  (X, Y) axes style control for line plots.

  The `axes` property of a `XYLinePlot` allows access to the several `x` and `y` axes by index. Linemaps can use any of the five such axes. In this example, we create two sets of data with different scales and the second y-axis is used on the right side of the plot:

      import numpy as np
      import tecplot as tp
      from tecplot.constant import PlotType, Color

      frame = tp.active_frame()

      npoints = 100
      x = np.linspace(-10,10,npoints)
      t = x**2
      p = 0.1 * np.sin(x)

      dataset = frame.create_dataset('data', ['Position (m)', 'Temperature (K)',
                                              'Pressure (Pa)'])
      zone = dataset.add_ordered_zone('zone', (100,))
      zone.values('Position (m)')[:] = x
      zone.values('Temperature (K)')[:] = t
      zone.values('Pressure (Pa)')[:] = p

      plot = frame.plot(PlotType.XYLine)
      plot.activate()
      plot.delete_linemaps()

      temp = plot.add_linemap('temp', zone, dataset.variable('Position (m)'),
                       dataset.variable('Temperature (K)'))
      press = plot.add_linemap('press', zone, dataset.variable('Position (m)'),
                               dataset.variable('Pressure (Pa)'))

      # Color the line and the y-axis for temperature
      temp.line.color = Color.RedOrange
      temp.line.line_thickness = 0.8

      ax = plot.axes.y_axis(0)
      ax.line.color = temp.line.color
      ax.tick_labels.color = temp.line.color
      ax.title.color = temp.line.color

      # set pressure linemap to second x-axis
      press.y_axis_index = 1

      # Color the line and the y-axis for pressure
      press.line.color = Color.Chartreuse
      press.line.line_thickness = 0.8

      ax = plot.axes.y_axis(1)
      ax.line.color = press.line.color
      ax.tick_labels.color = press.line.color
      ax.title.color = press.line.color

  Attributes

  `auto_adjust_ranges` | Automatically adjust axis ranges to nice values.
  `axis_mode` | Controls automatic adjustment of axis ranges.
  `grid_area` | Area bounded by the axes.
  `precise_grid` | Precise dot grid.
  `preserve_scale` | Preserve scale (spacing between ticks) on range change.
  `viewport` | Area of the frame used by the plot axes.

  Methods

  `x_axis`(index) | `XYLineAxis`: X-axis style control.
  `y_axis`(index) | `XYLineAxis`: Y-axis style control.

`XYLineAxes.``auto_adjust_ranges`

  Automatically adjust axis ranges to nice values.

  Axes limits will be adjusted to have the smallest number of significant digits possible:

      >>> plot.axes.auto_adjust_ranges = False

  Type

    `bool`

`XYLineAxes.``axis_mode`

  Controls automatic adjustment of axis ranges.

  Possible values: `Independent`, `XYDependent`.

  If set to `XYDependent`, then setting the range of one axis automatically scales the other indicated axes proportionally to maintain the aspect ratio of the plot, effectively zooming in or out. If set to `Independent`, adjusting the range of one axis has no effect on other axes. Defaults to `Independent` for XY line plots, `XYDependent` for 2D Cartesian plots. Example usage:

      >>> from tecplot.constant import AxisMode
      >>> plot.axes.axis_mode = AxisMode.Independent

  Type

    `AxisMode`

`XYLineAxes.``grid_area`

  Area bounded by the axes.

  This controls the background color and border of the axes:

      >>> from tecplot.constant import Color
      >>> plot.axes.grid_area.fill_color = Color.LightGreen

  Type

    `GridArea`

`XYLineAxes.``precise_grid`

  Precise dot grid.

  This is a set of small dots drawn at the intersection of every minor gridline. In line plots, the axis assignments for the first active mapping govern the precise dot grid. The precise dot grid option is disabled for the 3D Cartesian plots and Line plots when either axis for the first active line mapping uses a log scale:

      >>> plot.axes.precise_grid.show = True

  Type

    `PreciseGrid`

`XYLineAxes.``preserve_scale`

  Preserve scale (spacing between ticks) on range change.

  This maintains the axis scaling, i.e. the distance between values along the axis. If `False`, the axes length will be preserved when the range changes:

      >>> plot.axes.preserve_scale = False
      >>> # get axis via "plot.axes.x_axis(0)" for line plots
      >>> # or "plot.axes.x_axis" for field or sketch plots
      >>> axis.max = 10 # axis scale is changed (length is preserved)

  Type

    `bool`

`XYLineAxes.``viewport`

  Area of the frame used by the plot axes.

  Example usage:

      >>> plot.axes.viewport.left = 5
      >>> plot.axes.viewport.right = 95
      >>> plot.axes.viewport.top = 95
      >>> plot.axes.viewport.bottom = 5

  Type

    `Cartesian2DViewport`

`XYLineAxes.``x_axis`(index)

  `XYLineAxis`: X-axis style control.

      >>> plot.axes.x_axis(0).show = True

`XYLineAxes.``xy_ratio`

  X:Y axis scaling ratio in percent.

  This requires the axes to be in dependent mode:

      >>> from tecplot.constant import AxisMode
      >>> plot.axes.axis_mode = AxisMode.XYDependent
      >>> plot.axes.xy_ratio = 2

  Type

    `float`

`XYLineAxes.``y_axis`(index)

  `XYLineAxis`: Y-axis style control.

  There are five y-axes for each `XYLinePlot`, indexed from 0 to 4 inclusive:

      >>> plot.axes.y_axis(0).show = True

### XYLineAxis

class `tecplot.plot.``XYLineAxis`(axes, name, index)

`XYLineAxis.``adjust_range_to_nice`()

  Rounds the axis range to the nearest major axis increment.

  This method resets the axis-line label values such that all currently displayed label values are set to have the smallest number of significant digits possible.

  Example usage:

      >>> # get axis via "plot.axes.x_axis(0)" for line plots
      >>> # or "plot.axes.x_axis" for field or sketch plots

`XYLineAxis.``fit_range_to_nice`()

  Set range of axis to nice values near variable minimum and maximum.

  This method resets the range to equal the minimum and maximum of the data being plotted, but makes the axis values “nice” by setting labels to have the smallest number of significant digits possible,

      frame = tp.active_frame()
      plot = frame.plot(PlotType.Sketch)

      plot.axes.x_axis.show = True
      plot.axes.y_axis.show = True

      plot.axes.viewport.left = 10
      plot.axes.viewport.right = 90
      plot.axes.viewport.bottom = 10

  Attributes

  `auto_adjust_ranges` | Automatically adjust axis ranges to nice values.
  `axis_mode` | Controls automatic adjustment of axis ranges.

  `precise_grid` | Precise dot grid.
  `preserve_scale` | Preserve scale (spacing between ticks) on range change.
  `viewport` | Area of the frame used by the plot axes.
  `x_axis` | X-axis style control.
  `xy_ratio` | X:Y axis scaling ratio in percent.

  Type

    `bool`

`SketchAxes.``axis_mode`

  Controls automatic adjustment of axis ranges.

  Possible values: `Independent`, `XYDependent`.

  If set to `XYDependent`, then setting the range of one axis automatically scales the other indicated axes proportionally to maintain the aspect ratio of the plot, effectively zooming in or out. If set to `Independent`, adjusting the range of one axis has no effect on other axes. Defaults to `Independent` for XY line plots, `XYDependent` for 2D Cartesian plots. Example usage:

      >>> from tecplot.constant import AxisMode
      >>> plot.axes.axis_mode = AxisMode.Independent

    `PreciseGrid`

`SketchAxes.``preserve_scale`

  Preserve scale (spacing between ticks) on range change.

  This maintains the axis scaling, i.e. the distance between values along the axis. If `False`, the axes length will be preserved when the range changes:

      >>> plot.axes.preserve_scale = False
      >>> # get axis via "plot.axes.x_axis(0)" for line plots

`SketchAxis.``fit_range_to_nice`()

  Set range of axis to nice values near variable minimum and maximum.

  This method resets the range to equal the minimum and maximum of the data being plotted, but makes the axis values “nice” by setting labels to have the smallest number of significant digits possible,

  Note

  If the axis dependency is not independent then this method may also affect the range on another axis.

  Example usage:

      >>> # get axis via "plot.axes.x_axis(0)" for line plots

  This is the small (x, y, z) reference axis object which can moved, resized and modified using this class.

  By default, all 3D plots show the 3D orientation axis in the upper right of the frame. It can be repositioned by setting `position` as shown below:

      from os import path
      import tecplot as tp
      from tecplot.constant import Color

      examples_dir = tp.session.tecplot_examples_directory()
      infile = path.join(examples_dir, 'SimpleData', 'Sphere.lpk')
      dataset = tp.load_layout(infile)

      frame = tp.active_frame()
      plot = frame.plot()

      plot.axes.orientation_axis.position = 15, 15
      plot.axes.orientation_axis.color = Color.BrightCyan

      plot.axes.reset_range()
      plot.view.fit()
