Hi John,
yes, I can do a matplotlib.use('pdf') (As a matter of fact I use this
as a workaround right now). But I have to do this at the very
beginning of the code, i.e.
before the import of pyplot. Now, my routine has a --PLOT switch which
allows me to turn on the on-screen plotting.
Depending on that switch I now have to decide whether or not to call
matplotlib.use('pdf').
This means that I have a lot of imports interspersed with other code
which looks terrible.
Really I am pretty sure that a simple script like:
from matplotlib import pyplot as pp
pp.plot([1,2,3])
should not open a window. Only after a
pp.show()
the window should show up.
Note: I have tried to remove my .matplotlib directory. I have also checked
>>> pp.isinteractive()
False
Any help would be highly appreciated.
Maximilian
