Creates a Stream from a function.

Parameters:

funcCallable[[ArrayLike, ArrayLike], [ArrayLike, ArrayLike]]

Function to be plotted. Works with regular functions and lambda functions.

x_axis_rangetuple[float, float]

Range of x values.

y_axis_rangetuple[float, float]

Range of y values.

number_of_points_xint

Number of points to fill the x range. Defaults to 30.

number_of_points_yint

Number of points to fill the y range. Defaults to 30.

densityfloat or tuple[float, float]

Density of stream lines. Can be specified independently for the x and y coordinates by specifying a density tuple instead. Defaults to 1.

line_widthfloat

Width of the stream lines. Default depends on the figure_style configuration.

colorstr

Color of the stream lines. Default depends on the figure_style configuration.

color_mapstr or Colormap

Color map of the stream lines. Default depends on the figure_style configuration.

arrow_sizefloat

Arrow size multiplier. Default depends on the figure_style configuration.

Returns:

A Stream object from a function.
