plt.subplot eats my subplots #11435
Description
Bug report
Bug summary
plt.subplot eats my subplots. But it doesn't completely digest them, since they are still there, just not shown.
Creating a subplot grid with plt.subplots and in addition adding a plt.subplot removes those subplots from the grid, which are under the newly created subplot.
Creating the additional subplot via fig.add_subplot does not remove them.
Code for reproduction
import matplotlib.pyplot as plt
fig, ax = plt.subplots(2,3,
subplot_kw={"label" : "A"},
gridspec_kw={'width_ratios':[1,1,3]})
ax[0,2].plot([1,2,3])
axi = plt.subplot(133, label="B")
axi.plot([7,6,5], color="red")
axi.axis("off")
plt.show()
Actual outcome
Expected outcome
The expected outcome would be the same as with fig.add_subplot:
axi = fig.add_subplot(133, label="B")
axi.plot([7,6,5], color="red")
axi.axis("off")

I am currently looking at and editing those docstrings and that behavior is correct according to the docstrings and code.
plt.subplotdelete overlapping subplots andfig.add_subplotdoesn't.I don't know why it is a difference in behavior.

So you think this is desired? That feels a lot as if suddenly
plt.titlewould create a title below the axes whileax.set_titlecreates it above or so.fredrik-1 commentedon Jun 13, 2018
I don't understand why the feature exist but it is well documented https://matplotlib.org/devdocs/api/_as_gen/matplotlib.pyplot.subplot.html#matplotlib.pyplot.subplot

I see. My bad. I guess this can be closed, although I think this pretty annoying and should probably be changed at some point.

Matlab does this...

We can't blame everything on MATLAB, see #7377 (comment) and surrounding discussion (I haven't tried for subplot though).

Again, I wouldn't use
plt.subplotsandplt.subplotin the same figure and expect anything sensible to happen.
