==================================================
Combining two subplots using subplots and GridSpec
==================================================

Sometimes we want to combine two subplots in an axes layout created with
`~.Figure.subplots`.  We can get the `~.gridspec.GridSpec` from the axes
and then remove the covered axes and fill the gap with a new bigger axes.
Here we create a layout with the bottom two axes in the last column combined.

See also :doc:`/tutorials/intermediate/gridspec`.

import matplotlib.pyplot as plt

fig, axs = plt.subplots(ncols=3, nrows=3)
gs = axs[1, 2].get_gridspec()
# remove the underlying axes
for ax in axs[1:, -1]:
    ax.remove()
axbig = fig.add_subplot(gs[1:, -1])
axbig.annotate('Big Axes \nGridSpec[1:, -1]', (0.1, 0.5),
               xycoords='axes fraction', va='center')

fig.tight_layout()

plt.show()
