class graphinglib.Ellipse(x_center: float, y_center: float, x_radius: float, y_radius: float, angle: float = 0, fill: bool | Inherit = Inherit, fill_color: str | Inherit = Inherit, edge_color: str | Inherit = Inherit, line_width: float | Inherit = Inherit, line_style: str | Inherit = Inherit, fill_alpha: float | Inherit = Inherit, number_of_points: int = 100)[source]#

This class implements an Ellipse object with a given center, two radii and an optional rotation angle.

Parameters:

x_centerfloat: The x coordinate of the center of the ellipse.
y_centerfloat: The y coordinate of the center of the ellipse.
x_radiusfloat: The radius of the ellipse along the x axis.
y_radiusfloat: The radius of the ellipse along the y axis.
anglefloat, optional: The rotation angle of the ellipse in degrees. Defaults to 0.
fillbool, optional: Whether the ellipse should be filled or not. Default depends on the figure_style configuration.
fill_colorstr, optional: The color of the ellipse’s fill. Default depends on the figure_style configuration.
edge_colorstr, optional: The color of the ellipse’s edge. Default depends on the figure_style configuration.
line_widthfloat, optional: The width of the line. Typical range is 0.5 to 4. Default depends on the figure_style configuration.
line_stylestr, optional: The style of the line. Values include "-", "--", "-.", ":", "solid", "dashed", "dashdot", and "dotted". Default depends on the figure_style configuration.
fill_alphafloat, optional: The alpha value of the fill. Range is 0 (transparent) to 1 (opaque). Default depends on the figure_style configuration.
number_of_pointsint, optional: The number of points to use to approximate the ellipse. Default is 100 (covers approximately 99.9% of perfect ellipse area).

Notes

Color parameters accept Matplotlib color formats: named colors ("blue"), short color strings ("b"), hex strings ("#0000ff"), grayscale strings ("0.5"), and RGB/RGBA tuples with values between 0 and 1 ((0, 0, 1) or (0, 0, 1, 0.5)).

Methods
