I have a script that uses matplotlib to plot graphs both displayed as
a GUI and as PDF documents. The script may need to be run from remote
terminals without X11-passthrough so they way I would like it to work
is to use the default backend if X is available and, otherwise, fall
back to using the Agg backend. How can I do this?
I've been trying to catch a RuntimeError and then retry with a
different backend but part of matplotlib remains loaded and won't let
me change backend:
try:
import matplotlib.pyplot as plt
except RuntimeError:
# retry import but without GUI capability
import matplotlib
plt.use('Agg')
import matplotlib.pyplot as plt
Has anyone managed this?
Many thanks.
Alex
