If you're not afraid of contaminating your code with axes_grid toolkit,
instead
cax = fig.add_axes([0.9, 0.1, 0.1, 0.8]) # setup colorbar axes.
try
from mpl_toolkits.axes_grid import make_axes_locatable
import matplotlib.axes as maxes
divider = make_axes_locatable(ax)
cax = divider.new_horizontal("5%", pad=0.05, axes_class=maxes.Axes)
fig.add_axes(cax)
This way, the height of the colorbar always matches that of your main axes.
