How to perform subplot from existing axes with Matplotlib

Question

I would like to add two (or more) axes (ax1 and ax2 in my example), coming from different parts of my program, to a unique raw Figure.

Thus, in the first part of my program, I would do:

fig1, ax1 = plt.subplots(1, 1)
ax1.scatter(...)
ax1.imshow()
...

and in a second part of this same program:

fig2, ax2 = plt.subplots(1, 1)
ax2.plot(...)
...

I then would like to build a figure to incorporate these two axes ax1 and ax2, with something like:

fig = plt.figure()
fig.add_my_subplots(ax1, ax2)

• berna1111: Something like this?
• floflo29: That's actually the way I ended up i.e. by means of a function.

Answer 1

As it seems that an axis should be not linked/added to another Figure in Matplotlib, I came up with a more simple solution:

fig, (ax1, ax2) = plt.subplots(1, 2, sharex=True, sharey=True)
do_my_stuff_with_first_axis(ax=ax1)
do_my_stuff_with_second_axis(ax=ax2)
