Set Colorbar Range in matplotlib

Question

I have the following code:

import matplotlib.pyplot as plt

cdict = {
  \'red\'  :  ( (0.0, 0.25, .25), (0.02, .59, .59), (1., 1., 1.)),
  \'green\':  ( (0.0         


        

Answer 1

Use the CLIM function (equivalent to CAXIS function in MATLAB):

plt.pcolor(X, Y, v, cmap=cm)
plt.clim(-4,4)  # identical to caxis([-4,4]) in MATLAB
plt.show()
