Creates a scatter plot from a function and a range of x values.

Parameters:

funcCallable[[ArrayLike], ArrayLike]

The function to be plotted.

x_min, x_maxfloat

The scatter plot will be created for x values between x_min and x_max.

labelstr, optional

Label to be displayed in the legend.

face_colorstr or ArrayLike or None

Face color of the points. If an array of intensities is provided, the values are mapped to the specified color map. If None, marker faces are transparent.

edge_colorstr or ArrayLike or None

Edge color of the points. If an array of intensities is provided, the values are mapped to the specified color map. If None, marker edges are transparent. Default depends on the figure_style configuration.

color_mapstr or Colormap

Color map used when face_color or edge_color is an array of intensity values. Examples include "viridis", "plasma", and "coolwarm". Default depends on the figure_style configuration.

color_map_range: tuple[float, float], optional

The data range covered by the color map, given as (minimum, maximum).

show_color_barbool

Whether or not to display the color bar next to the plot. Default depends on the figure_style configuration.

marker_sizeint

Size of the points. Typical range is 10 to 100. Default depends on the figure_style configuration.

marker_stylestr

Style of the points. Common values include ".", ",", "o", "v", "^", "<", ">", "s", "p", "*", "h", "H", "+", "x", "D", "d", "|", "_", "P", "X", "None", " ", and "". Default depends on the figure_style configuration.

marker_edge_width: float

Line width of the marker edges. Typical range is 0 to 3 points. Default depends on the figure_style configuration.

alphafloat

Opacity of the scatter plot. Range is 0 (transparent) to 1 (opaque). Default depends on the figure_style configuration.

number_of_pointsint

Number of points to be plotted. Defaults to 30.

Returns:

A Scatter object created from a function and a range of x values.

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)). They may also be arrays of intensity values, which are mapped through color_map.
