Hi,
I'm a newbie to matplotlib. I'm embedding matplotlib (0,98.5.3) in a
pyqt application. I'm using the qt4 backend and its navigation
toolbar.
I wish to execute a certain function every time the view interval of
a figure is changed interactively (i.e. using the zoom rectangle or
the
axes
I'm sure everybody find this really sad... If he wants control over the
ploting capabilities, then why not have matplotlib and send him the script?I
know when I switched to matplotlib from matlab I wanted to be able to edit
directly the graph with point and click, but sometimes it is more powerful

This works, but is very slow for something that will be on the back end

Iterating in python is usually slow, so you should use numpy array
methods if possible. I've made a faster version. It gives the same
result for your test case, but you
Hi Vicent,
I think the following example may help you, althogh their might be a better
way:
##
import matplotlib.pyplot as plt
def callback(ax):
prints mode of toolbar after limits changed
e.g.
mode : zoom rect
mode : pan/zoom
Yes, Me feel sad as well. But I don't think he wants to learn python
and then matplotlib. He is not a computer professor after all.

thanks for your answer. It really helps. I didn't know about the mode

Thanks Eric and also Ryan,
interpolation='nearest' worked. Maybe if the correct person is
listening, this could be highlighted in the imshow documentation since
the default of interpolation=none is not doing 'nothing' IMHO.
Also, I have looked
This isn't strictly a matplotlib question, but I'm hoping
dual mac/linux users can provide some advice on converting png
files to quicktime movies using mencoder on Ubuntu or Centos.
So far I've found that
1) starting with
http://matplotlib.sourceforge.net/examples/animation/movie_demo.html
I use::
ffmpeg -r 60 -i frame%05d.png -vcodec wmv2 -b 2000k out.avi
And this works well to generate movies that play on Windows, Mac and
Linux. As a bonus, these movies can be included in Latex/Beamer output
using the movies15 package and played within the PDF via Adobe Reader on
Mac and
I produce all my movies in Ogg container + Theora compression. I use
ffmpeg2theora for that, available on all platforms:ffmpeg2theora --nosound
--optimize --width 1024 --height 768 --inputfps=15 --aspect 4:3
png/mov%04d.png -o movie.ogv

That's encouraging, thanks. I tried this and produced

Just to confirm: the two OSX users down the hall get a missing

I have successfully used
mencoder -nosound -ovc lavc \
-lavcopts vbitrate=5000:vcodec=mjpeg \
-mf type=png:fps=30 -o moviename.avi mf://\*.png -v
I don't think the resulting files are very compressed, but they play
well with quicktime.
Another option for the mac is of course
The default download from the Matplotlib page

which once again highlights basemap. (I think
this was fixed at one point.)

I saw this for windows when I was downloading .99. I just checked again in
