cax added using make_axes_locatable shows up at the middle of the image, instead of bottom while saving figures. I have tried .png and .pdf . The output from plt.show() is correct.

python 3.6.6 :: Anaconda custom (64-bit)
numpy version 1.15.3
matplotlib version 3.0.0

Here's a minimal script, which reproduces the result

import numpy as np
from matplotlib import pyplot as plt 
from mpl_toolkits.axes_grid1 import make_axes_locatable

epsilon = np.random.rand(128,128)
fig,ax = plt.subplots(figsize=(6,6))
cax = make_axes_locatable(ax).append_axes('bottom', size='5%', pad = 0.05)
im = ax.imshow(epsilon,origin='lower')
fig.colorbar(im,cax=cax,orientation='horizontal')
fig.tight_layout()
fig.savefig('test.png',dpi=200,bbox_inches='tight')
plt.show()

This has already been reported and will be fixed 3.0.1. To avoid until 3.0.1 is released don’t use tight layout or revert to 2.2.3.

Thanks and sorry for the bother.

Thank you for the information. I tried searching if it was already reported or not. I found similar issues but not the same.

I can confirm that this seems to work fine in the just-tagged v.3.0.1... This was closed by #12363
