Spacing between some subplots but not all

Question

I have a matplotlib plot in python with 3 subplots, all in 1 column.

I currently control the height of each subplot with:

gridspec.GridSpec(3, 1, hei         


        

Answer 1

In this particular case it's probably quickest to just add an invisible axes object between rows 2 and 3:

import matplotlib.pyplot as plt

gridspec = dict(hspace=0.0, height_ratios=[1, 1, 0.4, 3])
fig, axs = plt.subplots(nrows=4, ncols=1, gridspec_kw=gridspec)
axs[2].set_visible(False)

I looked through the documentation and it appears that variable grid spacing is not supported. So we have to make do with workarounds like this one.
