Core’s PlotBase#

Classes:

PlotBase(inertial_frame, zero_point, ...[, name])

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

class symmeplot.core.plot_base.PlotBase(inertial_frame: ReferenceFrame, zero_point: Point, sympy_object: Any, name: str | None = None)#

Bases: ABC

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

Parameters:

inertial_frame (sympy.physics.vector.frame.ReferenceFrame) – The reference frame with respect to which the object is oriented.
zero_point (sympy.physics.vector.point.Point) – The absolute origin with respect to which the object is positioned.
name (str, optional) – Name of the plot object. Default is the name of the object being plotted.

Notes

The format of expressions and therefore values is as follows:

tuple(self._values, tuples of expressions for children artists)

where self._values is tuple(expressions for own artists).

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`(args, *kwargs)	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:

artist (ArtistBase) – The artist to be added.
exprs (expression or tuple of expressions) – Args used to update the artist in the form of expressions.

property artists: tuple[ArtistBase, ...]#: Artists used to plot the object.

property children: tuple[PlotBase, ...]#: Child objects in the plot hierarchy.

get_expressions_to_evaluate() → tuple#: Return a tuple of the necessary expressions for plotting.

get_sympy_object_exprs() → tuple[Any, ...]#: Return the expressions used in plotting the sympy object.

property inertial_frame: ReferenceFrame#: The reference frame with respect to which the object is oriented.

property name: str#: Name of the plot object. Default is the name of the object being plotted.

property sympy_object: Any#: The absolute origin with respect to which the object is positioned.

update() → None#: Update the objects on the scene, based on the currect values.

property values: tuple#: List of evaluated values for the object’s variables.

abstract property visible: bool#

If the object is be visible in the plot.

Notes

Subclasses should also implement the setter of this property.

property zero_point: Point#: The absolute origin with respect to which the object is positioned.
