[Bug]: Colorbar is displaced when saving as .pdf with bbox_inches='tight' and by using inset_axes #27143
Description
Bug summary
I use imshow() with colorbar and inset_axes to zoom into the image. After saving the pdf with savefigure() and bbox_inches='tight' the colorbar is shifted.
Very similar to bug #25176, which has already been fixed.
The problem only occurs when using the bbox_inches='tight' option in combination with inset_axes.
Code for reproduction
import matplotlib.pyplot as plt
import numpy as np
import matplotlib.cbook as cbook
import matplotlib.cm as cm
from matplotlib.patches import PathPatch
from matplotlib.path import Path
np.random.seed(19680801)
delta = 0.025
x = y = np.arange(-3.0, 3.0, delta)
X, Y = np.meshgrid(x, y)
Z1 = np.exp(-X**2 - Y**2)
Z2 = np.exp(-(X - 1)**2 - (Y - 1)**2)
Z = (Z1 - Z2) * 2
fig, ax = plt.subplots()
im = ax.imshow(Z, interpolation='bilinear', cmap=cm.RdYlGn,
origin='lower', extent=[-3, 3, -3, 3],
vmax=abs(Z).max(), vmin=-abs(Z).max())
cb = plt.colorbar(mappable=im)
plt.show()
axins = inset_axes(ax, width='20%', height='20%', loc='upper right')
Z2 = axins.imshow(Z, interpolation='bilinear', cmap=cm.RdYlGn,
origin='lower', extent=[-3, 3, -3, 3],
vmax=abs(Z).max(), vmin=-abs(Z).max())
x1, x2, y1, y2 = -1,0,0,1
axins.set_xlim(x1, x2)
axins.set_ylim(y1, y2)
rectpatch, connects = ax.indicate_inset_zoom(axins, edgecolor = 'k',alpha=1, lw = 1)
connects[0].set_visible(False)
connects[1].set_visible(True)
connects[2].set_visible(True)
connects[3].set_visible(False)
fig.savefig("temp.pdf",
bbox_inches='tight',
transparent=True,
format="pdf")Actual outcome
Expected outcome
Somthing like this:
but with tight layout

You are mixing the axes_grid inset_axes (though you don't include the import) and the native indicate_inset_zoom. Suggest
which works fine with bbox_inches='tight'

Oh my mistake, I see it now.
Sorry for the confusion.
@jklymak thanks for the help.
