Hello matplotlib users,
Using the source tarball on sourceforge (0.98.5.3), having pyqt-4.4.4
working, pyobjc-2.2b2 too (for GUI), but no pygtk at all, pylab does
not work (a pylab based script simply display nothing, not even create
a window). Embedding in QT4 works fine.
even when using pythonw.

Yes, pcolor is inherently very slow, but flexible. Imshow is very fas
Hi dear users,
Recently I found pcolor took tremendously longer to draw a figure
than contour or imshow. I am wondering if anyone had the same
experience, or anyone knows why? Thank you very much!

Hello Mike,
Thanks for the quick reply - I'll try "path.simplify" as you suggest.
My actual data is pretty big and unruly, but I wrote a bit of code
that demonstrates the point dropping. This code plots three
single-point-wide peaks on a baseline of noise that is 'length' points
long. For smalle

Correction, this error occurs on all GUI backends I've tried (I don't
have gtk installed). The malloc error didn't occur on the other
backends until I tried to interact with the plot window.

Good find. The comment is out of date. It is now followed in all
backends. I will update the template.

Mike,
The matplotlibrc.template indicates that this is effective only for
vector backends; is the template comment incorrect?

I'm running into a really bizarre error that seems to have started
spontaneously (no changes I can think of were made to my system in the
last few days and mpl was plotting without problems up until a few
hours ago). When using WxAgg, the following code raises a malloc error.

Hi,
I am using matplotlib for some data vizualization. To ensure a
consistent user interface among the whole application, I do the
scrolling/zooming stuff myself. So, for a diagram, a horizontal
scrollbar is displayed below the diagram that enabled to shift along the
x axis. This is (part of) the
Yes, that's obviously what I should have started this thread with :)
this is how I convert the xml into "plottable" arrays:

"""extracts timestamps and 'what' from 'src' for 'name'"""
buffwhat = []
bufftime = []
sortedbyname = []

Hi all,
I am using the following rc params for the text font size

It's not off topic -- and I understand what you're trying to do much
better now.
I assume at some point you convert all of the xml into a Numpy array and
pass that to matplotlib? matplotlib will only keep a reference to the
Numpy array, which should be far more compact, and you can safely remo
sorry If my last message was confusing.
I'm exctracting data from an xml file (100megs of xml) which is stored
by my app as an array of dict in which I pick only some keys to plot.
I'm just trying to figure out if the gc is able to free some parts of
the dict (the un-plotted parts) by itself (and i
I don't follow... If you need to free the data, you have to ensure that
matplotlib doesn't need it, and the only way to do that is destroy the
figure that references it. It's virtually impossible to create a
dangling reference in Python (from within Python).

Thanks Mike,
I just wanted to be sure wether matplotlib had a copy or not.
I'll have to work on giving hints to the GC then...

Yes, Python is reference counted (with a garbage collector to handle
cycles etc.). So, yes, the matplotlib plot keeps a "reference" to your
data after you pass it in so it continue to redraw it as the plot is
panned/zoomed/resized etc. You can safely del your local reference, but

You can set the rcParam "path.simplify" to False to turn off this behavior.
However, the goal is that the simplification is not noticable -- if it
is that may be a bug. Are you able to share your data so I can look
into this further?
Cheers,
