matplotlib.pyplot.axvspan#

matplotlib.pyplot.axvspan(xmin, xmax, ymin=0, ymax=1, **kwargs)[source]#

Add a vertical span (rectangle) across the Axes.

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

Parameters:

xminfloat: Lower x-coordinate of the span, in data units.
xmaxfloat: Upper x-coordinate of the span, in data units.
yminfloat, default: 0: Lower y-coordinate of the span, in y-axis units (0-1).
ymaxfloat, default: 1: Upper y-coordinate of the span, in y-axis units (0-1).

Returns:

Polygon: Vertical span (rectangle) from (xmin, ymin) to (xmax, ymax).
