Hi,
I have compiled v.0.90.1 on RHEL 5. By default, the GTKAgg backend is being
used (TkAgg cannot be set, as TkInter is not installed on the system, I
think. It throws a "NO Module named Tkinter" error).
At any rate, a test session is as follows:
import pylab
pylab.plot ( [1,2,3],[1,2,3],'-or') #Wait for a long time, up to 3-4 minutes
pylab.show() # Display the graph. Quite fast <1sec
This delay is very unusual, and does not happen on my laptop. Does anyone have
any ideas?
Thanks!
Jose

This is not happening for me. Does it happen every time you run mpl
or just the first time after you install. Run some test script, eg
> cat test.py
from pylab import *
plot([1,2,3])
show()
with
> python test.py -dGTKAgg --verbose-debug
and see if you can get some clue what mpl is doing when it hangs.
Also, post the verbose output to the list.
Thanks,

Thanks for your reply. I think it might well be a fonts problem. Here's the

So, it's not finding any of the fonts above, and coming up with Verta.ttf.
Could this be the problem? And if it is, what can I do to solve it?
Thanks!

PS and Agg work fast enough, and produce meaningful PS and PNG output files
(as well as popping up a window with the plot). GTKAgg is the one taking a
long time to pop up, AND results in an empty PNG file. I am attaching the
debug output of the GTKAgg mode. (Delay occurs @ #[... DELAY....] line.

Sorry, my wrong. There's no such window when running with Agg. There was
another window from another session which I mistakenly thought had to do with
these tests. Agg and PS produce PNG and PS files respectively, with no window
popping up. Apologies for that.
Also, post the exact script you are running....
It is in the beginning of my debug output, but I'll re-send the script and
command line:
*script (test.py):
from pylab import *
plot([1,2,3])
show()
savefig("myfig")
*command line:
python test.py -dGTKAgg --verbose-debug-annoying
Thanks,
