Putty SSH-Connection doesn't show plots from matplotlib

Question

I am connecting to a Server via Putty and I need to plot some stuff. I am using windows on my PC and it is linux on the server. Is there a way to see the plots on my PC when I run a script from the SSH-connection? I tried every possible argument for the matplotlib.use() and it is still not working.

These GTK3Agg, GTK3Cairo, MacOSX, nbAgg, Qt4Agg, Qt4Cairo, Qt5Agg, Qt5Cairo, TkAgg, TkCairo, WebAgg, WX, WXAgg, WXCairo give me this error

Gdk-CRITICAL **: 16:41:41.238: gdk_cursor_new_for_display: assertion 'GDK_IS_DISPLAY (display)' failed

And these agg, cairo, pdf, pgf, ps, svg, template give me no error, but also no output.

Is it even possible to get a plot when you use Putty for connection to anther sever?

PuTTY (and other TTY clients) are just that - teletype. You cannot create windows in them because they aren't capable of graphics. The best solution for seeing these plots would be to save the plot as an image file and then transfer it via FTP or something.

Or, if your remote machine is already running a graphical environment, you could try using VNC or another remote desktop with graphics capability.
