../mpl-tests/issue11769.py:23: MatplotlibDeprecationWarning: shading='flat' when X and Y have the same dimensions as C is deprecated since 3.3.  Either specify the corners of the quadrilaterals with X and Y, or pass shading='auto', 'nearest' or 'gouraud', or set rcParams['pcolor.shading'].  This will become an error two minor releases later.
  plt.pcolormesh(x,y,map2,cmap='viridis',vmin=np.nanmin(map2),vmax=np.nanmax(map2))
