Python matplotlib decrease size of colorbar labels

Question

I need your help! I have a plotting code which is the following:

fig = plt.figure()
ax1 = fig.add_subplot(111)

imax1 = ax1.imshow(data,interpolation = \'nea         


        

Answer 1

If you are here because you're trying to increase font size, but some numbers disappear because of big size with the above answer, you can do

cbar = plt.colorbar()
for t in cbar.ax.get_yticklabels():
     t.set_fontsize(20)

Answer 2

Aha! Found the answer here:

cbar.ax.tick_params(labelsize=10) 

P.S. Upvote that answer and give Paul some love!
