I have 2 arrays arr1 contains correlation values of between -1 to 1
arr2 contains nans and 1's but same shape as arr1
arr1 = 180 * 360
arr2 = 180 * 360
I want to plot arr2 on arr1 as a hatch like this
plt.contourf(lon,lat,arr1)
plt.pcolor(lon,lat, arr2, hatch = '...', alpha=0)
the problem here is that some of the colors in the hatched are covered by
the contour plot of arr1
How can I make the hatches apear on top without being blocked by the
contours of arr1
sincerely
