matplotlib.axes.Axes.axhspan

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

Add a horizontal span (rectangle) across the axis.

Draw a horizontal span (rectangle) from ymin to ymax. With the default values of xmin = 0 and xmax = 1, this always spans the xrange, regardless of the xlim settings, even if you change them, e.g., with the set_xlim() command. That is, the horizontal extent is in axes coords: 0=left, 0.5=middle, 1.0=right but the y location is in data coordinates.

Parameters:

ymin : float: Lower limit of the horizontal span in data units.
ymax : float: Upper limit of the horizontal span in data units.
xmin : float, optional, default: 0: Lower limit of the vertical span in axes (relative 0-1) units.
xmax : float, optional, default: 1: Upper limit of the vertical span in axes (relative 0-1) units.

Returns:

Polygon : Polygon

Other Parameters:

**kwargs : Polygon properties.
