Stokes flow pressure display problems

[likeduck]

Hi prof，
Is there anyway to diaplay colorbar in the figure of Stokes flow's pressure? I got independent one like the following image：

I try many times in 3D PNM but failed. Could you give me some idea?

Thank you so much!

This seems like a matplotlib problem no? I was actually learning how to use colorbars recently, like this:

fig, ax = plt.subplots()
handle = ax.imshow(somthing here)
plt.colorbar(handle)

The point is you have to catch the 'handle' returned when calling imshow, so that you can pass it to the colorbar function.

OOOh! It is indeed the problem of matplotlib. I am learning it, too. And I find that there was 1 dimension in phase['pore.pressure'] so the ax.imshow() didn't work. When I extend phase['pore.pressure'] to 2dimension by copying itself, the ax.imshow() failed to plot. Anyway, it was an attractive question！I will learn more deeply.
Thanks for your kind reply!
