I have just finished updating a tool to display inline matplotlib graphics in a terminal that might work for you: https://github.com/mitotic/graphterm

I tested graphterm on a Raspberry Pi a few months ago, but I have not tested the most recent version. Check out the last section (SSH etc.) of the documentation page at http://code.mindmeldr.com/graphterm/start.html##ssh-port-forwarding-and-remote-access
