[Bug]: About drawing 3D picture content title display incomplete problem #28515
Description
Bug summary
I had this problem while drawing 3D drawings. When I used the older version, I could fully display the Z-axis headings. When I use the latest version, the Z-axis title is not displayed. I tried everything. I couldn't work it out. Help, thank you.
Code for reproduction
from mpl_toolkits.mplot3d import axes3d
import matplotlib.pyplot as plt
from matplotlib import cm
plt.rcParams['savefig.bbox'] = 'tight'
ax = plt.figure().add_subplot(projection='3d')
X, Y, Z = axes3d.get_test_data(0.05)
# Plot the 3D surface
ax.plot_surface(X, Y, Z, rstride=8, cstride=8, alpha=0.3)
# Plot projections of the contours for each dimension. By choosing offsets
# that match the appropriate axes limits, the projected contours will sit on
# the 'walls' of the graph
ax.contourf(X, Y, Z, zdir='z', offset=-100, cmap=cm.coolwarm)
ax.contourf(X, Y, Z, zdir='x', offset=-40, cmap=cm.coolwarm)
ax.contourf(X, Y, Z, zdir='y', offset=40, cmap=cm.coolwarm)
ax.set(xlim=(-40, 40), ylim=(-40, 40), zlim=(-100, 100),
xlabel='X', ylabel='Y', zlabel='Z')
# plt.gcf().subplots_adjust(left=0,top=1,bottom=0, right=1)

I was very confused. Can't find the answer. Is there anyone here who can help me? :(

I believe this is probably just the Z axis label getting cropped out? Probably a downstream effect of the change in #25272. But more widely an instance of this issue where there's a disconnect between different bounding boxes: #19519 #23450
MoonCapture commentedon Jul 7, 2024
When I ran #25272, I also had an issue with the Z-axis not being displayed. I found that the issue was caused by a change to version 3.6.0, but I don't know how to fix it.

I can confirm this is an issue with the bounding box being too small and cropping out the Z axis label. If I rotate the plot a bit then I can see it again (chosen here to partially clip the label).
@MoonCapture if you comment out the line
plt.rcParams['savefig.bbox'] = 'tight'then does it work for you? 3D axes don't play super well with the figure bounding boxes right now.MoonCapture commentedon Jul 7, 2024
It doesn't work

Yes. When I use vscode, it doesn't display either.

This is a duplicate of #28117.

Hey @MoonCapture, VSCode is using the same jupyter backend that is overriding that setting, so I think it's expected that this issue is manifesting there as well.
If you copy-paste your code into a standalone
.pyfile, then I can confirm that commenting out theplt.rcParams['savefig.bbox'] = 'tight'line resolves the cropping issue on my machine.MoonCapture commentedon Jul 9, 2024
Thank you very much! That really solved my problem. It's possible that some changes in version 3.6.0 prompted this change.
