[Matplotlib-users] same plot on several backends?

[Norbert N. <Nor...@gm...>]

Hi there,

probably a trivial question, but somehow, I'm stuck anyway:

I have the following script:

----------
#!/usr/bin/env python
import matplotlib.matlab
... do some data preparation ...
plot(something)
show()
savefig("output.eps")
----------

If I call this script with the -dGtkAgg option, it displays the plot on screen 
and saves an empty eps file. If I call it with -dPS, it displays nothing and 
outputs the correct eps - so far everything as I would expect it.

Up to now, I just used the -dGtkAgg backend (as default) to get an impression 
about the plots and then ran the script again to create the .eps.

Now, I would like the script to do both in one run: display the plot on 
screen, and save it to disk at the same time.

Somehow I have not achieved doing so. My first idea was to place
 matplotlib.use('PS')
right before the savefig, but that does not change anything and still writes 
an empty .eps file.

What should I do?

Thanks,
Norbert
