Pyqtgraph’s PlotBase¶

Plot base definition for pyqtgraph plotting backend.

Classes:

PgPlotBase(inertial_frame, zero_point, ...)

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

class symmeplot.pyqtgraph.plot_base.PgPlotBase(inertial_frame: sympy.physics.vector.frame.ReferenceFrame, zero_point: sympy.physics.vector.point.Point, sympy_object: object, name: str | None = None)¶

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.

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 current 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, ...]) → None¶

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: sympy.physics.vector.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: object¶: The absolute origin with respect to which the object is positioned.

update() → None¶: Update the objects on the scene, based on the current values.

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

property zero_point: sympy.physics.vector.point.Point¶: The absolute origin with respect to which the object is positioned.
