Python Matplotlib plt.show() does not return the figure

I remote login a server using ssh -X ***@remote.arizona.edu (This remote server is a Linux system) and tried to make some plots using Python, I had the following errors:

_tkinter.TclError: no display name and no $DISPLAY environment variable

Then I fixed this error by the adding the commands before I import any matplotlib:

import matplotlib
matplotlib.use('Agg')
matplotlib.matplotlib_fname()

Now it runs well. But the problem is that there is no figure displayed even if I had the command plt.show(). My old computer used Ubuntu 16.04 before, there is no such problem. Now I switched to MacBook Air, then I had this issue. It must be some Mac setting issues. Any thoughts to fix this issue?

You need to install XQuartz on your Macbook. Then make sure the DISPLAY variable in your remote shell is set to your local X server. Now the remote matplotlib should show the figure on your Macbook.
