I'm trying to find a way to hide part of a line in a matplotlib plot. Say I have a line with x values from 0 to 100 and I want to hide a portion of the line form x = 20 to x = 30. Is there any efficient way to do this? Thanks!

- plot the parts 0-20 and 30-100 separatelywim– wim2016-05-12 04:34:30 +00:00Commented May 12, 2016 at 4:34

You could mask part of the array, then matplotlib doesn't plot it:
import numpy as np import matplotlib.pylab as pl x = np.arange(100) y = np.cos(x/10.) pl.figure() pl.subplot(121) pl.plot(x, y) # Mask part of array y2 = np.ma.masked_where(((x>20)&(x<30)), y) pl.subplot(122) pl.plot(x, y2)
