I had problems using pyplot over ssh because it can assume there's a display and fail when it couldn't find one. Maybe this has changed. I use the OO interface.

Changing the plot backend should fix this. import matplotlib matplotlib.use('Agg') import matplotlib.pyplot as plt https://stackoverflow.com/questions/2801882/generating-a-png-with-matplotlib-when-display-is-undefined https://stackoverflow.com/questions/2801882/generating-a-png...

  I believe Agg is only for bitmap output. While there are probably backends that work with a headless system, I find the OO option much more flexible.

    Agg works for all outputs. I use it in combination with OO over ssh all the time.
