matplotlib.axes.Axes.axhspan#

Axes.axhspan(ymin, ymax, xmin=0, xmax=1, **kwargs)[source]#

Add a horizontal span (rectangle) across the Axes.

The rectangle spans from ymin to ymax vertically, and, by default, the whole x-axis horizontally. The x-span can be set using xmin (default: 0) and xmax (default: 1) which are in axis units; e.g. xmin = 0.5 always refers to the middle of the x-axis regardless of the limits set by set_xlim.

Parameters:

yminfloat

Lower y-coordinate of the span, in data units.

ymaxfloat

Upper y-coordinate of the span, in data units.

xminfloat, default: 0

Lower x-coordinate of the span, in x-axis (0-1) units.

xmaxfloat, default: 1

Upper x-coordinate of the span, in x-axis (0-1) units.

Returns:

Rectangle

Horizontal span (rectangle) from (xmin, ymin) to (xmax, ymax).
