How To Hatch Polycollection Instance?

Is it possible to hatch PolyCollection instance? I want to hath a PolyCollection returned from fill_betweenx. import matplotlib.mlab as mlab from matplotlib.pyplot import figure, s

Solution 1:

It's a bit of a hack, but you should be able to do something like this:

import matplotlib.pyplot as plt
import numpy as np
from matplotlib.patches import PathPatch

x = np.arange(0.0, 2, 0.01)
y1 = np.sin(2*np.pi*x)
y2 = 1.2*np.sin(4*np.pi*x)

fig, ax = plt.subplots()
pc = ax.fill_betweenx(x, 0, y1, color='blue')

# Now we'll add the hatches...for path in pc.get_paths():
    patch = PathPatch(path, hatch='/', facecolor='none')
    ax.add_patch(patch)

plt.show()
