I need to produce a plot with certain ranges highlighted. The problem is that I cannot use axvspan
that would fill the span area from top to bottom. I need to limit the spanned area only to the bottom, as can be seen in the image below, where the range 0.5-1.5 is highlighted:
Is there a way to achieve this in matplotlib?

You can define the boundaries of your rectangle (xmin
, xmax
, ymin
, ymax
) in axvspan
.
import numpy as np import matplotlib.pyplot as plt x = np.linspace(-1.0, 2.0, 301) y = np.sin(2.0 * np.pi * x) plt.plot(x, y) plt.axvspan(0.5, 1.5, ymax=0.05, color="gray") plt.show()
Note that ymin
and ymax
are relative coordinates (between 0 and 1).
