PolarPlane

Qualified name: algan.mobs.manim\_compat.PolarPlane

class PolarPlane(radius_max=4.0, size=None, radius_step=1, azimuth_step=None, azimuth_units='PI radians', azimuth_compact_fraction=True, azimuth_offset=0, azimuth_direction='CCW', azimuth_label_buff=0.1, azimuth_label_font_size=24, radius_config=None, background_line_style=None, faded_line_style=None, faded_line_ratio=1, make_smooth_after_applying_functions=True, **kwargs)

Bases: ManimCompatMob

Creates a polar plane with background lines.

Parameters:

• azimuth_step (float | None) –

  The number of divisions in the azimuth (also known as the angular coordinate or polar angle). If None is specified then it will use the default specified by azimuth_units:

  • "PI radians" or "TAU radians": 20

  • "degrees": 36

  • "gradians": 40

  • None: 1

  A non-integer value will result in a partial division at the end of the circle.

• size (float | None) – The diameter of the plane.

• radius_step (float) – The distance between faded radius lines.

• radius_max (float) – The maximum value of the radius.

• azimuth_units (str) –

  Specifies a default labelling system for the azimuth. Choices are:

  • "PI radians": Fractional labels in the interval \(\left[0, 2\pi\right]\) with \(\pi\) as a constant.

  • "TAU radians": Fractional labels in the interval \(\left[0, \tau\right]\) (where \(\tau = 2\pi\)) with \(\tau\) as a constant.

  • "degrees": Decimal labels in the interval \(\left[0, 360\right]\) with a degree (\(^{\circ}\)) symbol.

  • "gradians": Decimal labels in the interval \(\left[0, 400\right]\) with a superscript “g” (\(^{g}\)).

  • None: Decimal labels in the interval \(\left[0, 1\right]\).

• azimuth_compact_fraction (bool) – If the azimuth_units choice has fractional labels, choose whether to combine the constant in a compact form \(\tfrac{xu}{y}\) as opposed to \(\tfrac{x}{y}u\), where \(u\) is the constant.

• azimuth_offset (float) – The angle offset of the azimuth, expressed in radians.

• azimuth_direction (str) –

  The direction of the azimuth.

  • "CW": Clockwise.

  • "CCW": Anti-clockwise.

• azimuth_label_buff (float) – The buffer for the azimuth labels.

• azimuth_label_font_size (float) – The font size of the azimuth labels.

• radius_config (dict[str, Any] | None) – The axis config for the radius.

• background_line_style (dict[str, Any] | None)

• faded_line_style (dict[str, Any] | None)

• faded_line_ratio (int)

• make_smooth_after_applying_functions (bool)

• kwargs (Any)
