Thank you for you answer. I think you didn’t understand what I want exactly ? ,I want to plot eigenvector in three dimensions Similar to image that attached below. [GS2DAnd3DPlotsExample_05]

Hello, define before the loop phi = Function(V) and inside the loop do phi.vector().set_local(rx) plot(phi, mode="warp")

That’s very kind of you. Thank you.

Please encapsulate your code in ``` for proper formatting, and reduce the size of your code by removing all lines of the code that is after the error message to make it more readable for others. See Read before posting: How do I get my question answered? on how to post a minimal working example.

Thank for your reply. I don’t have a problem or error in my code. I just want to make the figure very clearly. [Figure_1-4]

Then why did you post all the code, it obscures the question. And whenever you post code it should be formatted. To run your code, anyone has to do a lot of manual formatting. I ran you script using the latest development docker image , replacing plt.show() with plt.savefig("test.png") and got the f…

vtkplotter can visualize 2D and 3D solutions easily e.g.: # ... from vtkplotter.dolfin import plot plot(phi, warpZfactor=150, cmap='gist_earth_r', lighting='plastic') [image]
