pcolormesh with missing values?

Question

I have 3 1-D ndarrays: x, y, z

and the following code:

import numpy as np
import matplotlib.pyplot as plt
import scipy.interpolate as spinterp

## de         


        

Answer 1

Note that the explicit masking is no longer necessary in matplotlib master as arrays are now masked automatically internally. Will be incorporated into matplotlib >2.1. See my merged pull request https://github.com/matplotlib/matplotlib/pull/5451

So now it's as simple as

plt.pcolormesh(X,Y,Z.T)
