Bases: PlotBase

Class with the basic attributes and methods for the plot objects.

Parameters:

Methods:

add_artist(artist, exprs)

Add an artist to the plot object.

get_expressions_to_evaluate()

Return a tuple of the necessary expressions for plotting.

get_sympy_object_exprs()

Return the expressions used in plotting the sympy object.

plot(view)

Plot the associated plot objects.

update()

Update the objects on the scene, based on the currect values.

Attributes:

artists

Artists used to plot the object.

children

Child objects in the plot hierarchy.

inertial_frame

The reference frame with respect to which the object is oriented.

name

Name of the plot object.

sympy_object

The absolute origin with respect to which the object is positioned.

values

List of evaluated values for the object's variables.

visible

If the object is be visible in the plot.

zero_point

The absolute origin with respect to which the object is positioned.

add_artist(artist: ArtistBase, exprs: Expr | tuple[Expr, ...])#

Add an artist to the plot object.

Parameters:
