get_axis_labels(x_label='x', y_label='y', z_label='z')[source]#

Defines labels for the x_axis and y_axis of the graph.

For increased control over the position of the labels, use get_x_axis_label(), get_y_axis_label(), and get_z_axis_label().

Parameters:

  • x_label (float | str | Mobject) – The label for the x_axis. Defaults to MathTex for str and float inputs.

  • y_label (float | str | Mobject) – The label for the y_axis. Defaults to MathTex for str and float inputs.

  • z_label (float | str | Mobject) – The label for the z_axis. Defaults to MathTex for str and float inputs.

Returns:

A VGroup of the labels for the x_axis, y_axis, and z_axis.

Return type:

VGroup
