Bug summary

The position of exponent label is wrong for the extended colorbar when the colorbar location is left or right.

Code for reproduction

import matplotlib.pyplot as plt
import numpy as np

N = 18
state = np.random.RandomState(51423)
data = 1e5 * np.cumsum(state.rand(N, N), axis=0)
fig, ax = plt.subplots()
m = ax.pcolor(data)
fig.colorbar(m, ax=ax, extend='max', location='right')
fig.colorbar(m, ax=ax, extend='max', location='left')

Sorry this broke. That makes sense, and is a consequence of us changing the colorbar axes bounds to not include the extends in 3.5. I'm not sure off the top of my head what the fix is, but hopefully will be fixed in 3.5.2 or perhaps the next bug fix release.

OK - fix wasn't too bad; confident this will be fixed 3.5.2.

Please do let us know of any other colorbar oddities; 3.5 was a large change....
