matplotlib.axes.Axes.axvspan

Axes.axvspan(self, 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).
