Matplotlib: shaded regions¶
Use the fill function to make shaded regions of any color tint. Here is an example.
from pylab import * x = arange(10) y = x # Plot junk and then a filled region plot(x, y) # Make a blue box that is somewhat see-through # and has a red border. # WARNING: alpha doesn't work in postscript output.... fill([3,4,4,3], [2,2,4,4], 'b', alpha=0.2, edgecolor='r')
