Hi,
I would like to iterate over fig.axes and apply some changes to regular
axes and skip those belonging to colorbars.
What's the best way (having only fig object) to detect if an axis
belongs to a colorbar or not?
Thanks for an advice.
Best regards,
Stefan
No, I don't think there is a way, really. From the perspective of the
figure object, the colorbar looks just like another axes object. There
might be a trick that might work in some cases, but they would be highly
fragile. It would be better to just capture the colorbar object directly,
somehow.

On a related note, I was thinking that doing something like
`fig.findobj(mpl.colorbar.ColorbarBase)` would help you, but it raises an
error instead:
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File
"/home/jfoxrabi/miniconda3/lib/python3.5/site-packages/matplotlib/artist.py",
line 975, in findobj
if matchfunc(c):

line 307, in __init__
self.set_label(label)

line 448, in _set_label
self.ax.set_ylabel(self._label, **self._labelkw)
AttributeError: 'Rectangle' object has no attribute 'set_ylabel'
What is wrong about the way I am trying to use `findobj`?
Here is the code I was testing with, for reference:
import numpy as np
import matplotlib as mpl
from matplotlib import pyplot as plt
x = np.arange(10)
y = np.arange(10)
X, Y = np.meshgrid(x, y)
z = X * Y
ax = plt.pcolor(X, Y, z)
plt.colorbar()
fig = ax.figure
fig.findobj(mpl.colorbar.ColorbarBase)

mpl.colorbar.ColorbarBase is not a subclass of Artist, so findobj() doesn't
detect that you want to match against that object type.
