ptvis.utils.make_annulus_sector_shape

ptvis.utils.make_annulus_sector_shape(x, y, inner_radius, outer_radius, start_angle, stop_angle, connect_arcs=True, tol=0.0001)

Make a shape object of an annulus sector.

Parameters:

• x (float) – X coordinate of a center.

• y (float) – Y coordinate of a center.

• inner_radius (float) – Radius of an inner arc.

• outer_radius (float) – Radius of an outer arc.

• start_angle (float) – Angle from which an annulus sector starts in degrees.

• stop_angle (float) – Angle at which an annulus sector stops in degrees.

• connect_arcs (bool, optional) – If True, endpoints of inner and outer arcs are connected by lines.

• tol (float, optional) – Tolerance for the relative error of the radius of an arc.

Returns:

plotly.graph_objects.layout.Shape – Shape object of an annulus sector.

Notes

An arc is approximated by a cubic Bézier curve [1].
