graphinglib.Curve

class graphinglib.Curve(x_data: ArrayLike, y_data: ArrayLike, label: str | None = None, color: str = 'default', line_width: float | Literal['default'] = 'default', line_style: str = 'default')

This class implements a general continuous curve.

Parameters:

x_data, y_dataArrayLike

Arrays of x and y values to be plotted.

labelstr, optional

Label to be displayed in the legend.

colorstr

Color of the curve. Default depends on the figure_style configuration.

line_widthfloat

Width of the curve. Default depends on the figure_style configuration.

line_stylestr

Style of the curve. Default depends on the figure_style configuration.
