Re: [Matplotlib-users] draw() doesn't always force draw on qt4?
Hello Glen, I'm not sure, but maybe it would help to use ax = subplot(111) and ax.plot(arange(it)) instead of plot(arange(it)) or to call a second draw() after plotting. regards Matthias On Wednesday 23 April 2008 20:49:46 Glen W.

Re: [Matplotlib-users] Different between canvas.draw() and canvas.restore_region()??
I'm confused, because I don't see any place where self.canvas.draw is called in the code1 version. Also, when I resize the figure, the background region changes, so the plot gets messed up as I have noticed before with this method. Does anyone know a good way to recapture a clean background, in particular when the image is resized?

Re: [Matplotlib-users] font always the same in PNG
The font lookup mechanism has been much improved in 0.91.2 -- you may
want to try using that. In 0.90.x, often if you don't get a perfectly
exact match for a font, it reverts back to the default Vera Sans.
Vera Sans, however, is not a fixed-width font. Can you provide the png
file of fonts_demo.py so I can be sure of what is happening? One way to
diagnose this is to do
rc(verbose, level=debug-annoying)
which will print out a bunch of stuff related to font lookup. Attach
the output here and I'll have a look at it to try to figure out what may
be going wrong.

Re: [Matplotlib-users] legend is not properly drawn when a plot is saved in 'pdf' format
I don't suspect another distro will make a difference. The bug is in
matplotlib's Cairo backend (it's interface to Cairo), not in Cairo
itself. Change your backend to PDF and you can avoid this bug. In the
meantime, we'll need to fix the Cairo backend in matplotlib. Sorry I
wasn't clearer the first time.

Re: [Matplotlib-users] failed to save in 'eps' format when I use latex environment
On Thursday 24 April 2008 08:53:47 am you wrote:
Although the 'align' environment inside the figure environment does not
cause any error,
tt seems like that the 'put' command from the 'picture' environment in
LaTeX does not

As you pointed out, my problem is coming from the limitation in LaTeX.
However, there are two things I do not understand still.
First, saving a plot with the align environment in 'eps' format had worked
in the previous
version of matplotlib (0.90.1 from ubuntu gutsy 7.10). What has been
changed?
Nothing with the latex support, as far as I can tell from the changelogs.
Secondly, saving in a 'png' or 'pdf' format works still. What's the
difference?
Saving a ps or eps file goes through the procedure of embedding the figure in
a latex document in order for PSFrags to do its job and convert some tags
into actual text. That way you get scalable output. png just renders the text
as images, not as text. pdf output uses dviread.py to parse the dvi files
created by latex, get the font layout information, and place the glyphs.
dviread was not available when we added support to the eps/*agg backends, it
was contributed later by Jouni Seppanen. dviread is a simpler and more
elegant approach than the way it is done in eps/*agg, but there are some
subtle and difficult to resolve limitations of dviread (like rendering greek
letters in math mode) that have prevented us from using it everywhere. Jouni,
would you care to comment?

Jouni, would you care to comment? The details are a little complicated, but yes, dviread.py lacks some features of the font support in dvips. The PS backend calls dvips and so gets to use all the font machinery in a modern TeX system, and dviread doesn't (yet) implement all the features. Another potential problem is that dviread makes more assumptions about the TeX system than the PS backend, and I have only tested it on TeX Live on a Mac. Both TeX Live and teTeX on a Unix-ish system should be fine, but I have no idea about TeX implementations on Windows, or any commercial implementations. For various reasons, I haven't had much time recently to hack on matplotlib, but improving dviread is high on my todo list when I do find the time. -- Jouni K.

[Matplotlib-users] find_best_location for axes ?
Hi, I want to inset one axes within a larger one... as in http://matplotlib.sourceforge.net/screenshots/axes_demo.py and http://matplotlib.sourceforge.net/screenshots/axes_demo_small.png but I was wondering if there is an option similar to best location in the legend function. So, instead of hardwiring, like: a = axes([.65, .6, .2, .2], axisbg='y'), I like it automatically place the inset in a best location!

It just quietly finished otherwise. Did I miss something here? Does it work if you put this into your matplotlibrc? verbose.level: debug-annoying (Note it's debug-annoying, not simply annoying) I've linked the output of fonts_demo.py to; https://www.box.net/shared/static/o693hq3soo.png Hmm. That font is definitely not Vera Sans. Something really odd is going on here. I can appreciate that goal -- and AFAIK it does work for other users on Ubuntu 7.10 so there is probably just some configuration problem here that we can hopefully get to the bottom of. Do you have any customizations in your matplotlibrc? Cheers, Mike Mike, I've not made any other changes to matplotlibrc. In fact I only just now have copied the one in /etc to my $HOME/.matplotlib directory. It still seemed to pick up the /etc version as you'll see below, I guess coz I was sudo'd as root? :) anyway... Interesting the font search path seems to only include mpl-data fonts, but it does seem to know about the ones in /usr/share/fonts/truetype/freefont. Then fails to use one, so we're always back to cmr10. The output below was for my test plot but it's pretty much the same (longer) story for fonts_demo.py I tried copying all the freetype fonts into mpl-data/font and everything came out FreeSansOblique. Still failed to find the correct font, but used something a little closer. What do you make of it? I'll be away for a while but I'll check the list if I can.

Re: [Matplotlib-users] OSX build under universal python fails
Chris,
Based on recent emails, this looks like a problem attributed to the gcc
version, not the python version. Suggested solutions are compile with
the -Os flag or use gcc 4.2.

See my message yesterday for more detail. Hey Chris, I read your post and perhaps I am missing the obvious, but my basic question is: apple provides libpng and freetype with xcode which ships with their computers (an optional install from their cd) and these work fine with MPL, so why should we require an external dependency?

Re: [Matplotlib-users] Different between canvas.draw() and canvas.restore_region()??
On Thu, Apr 24, 2008 at 2:43 AM, G Jones [EMAIL PROTECTED] wrote: I'm confused, because I don't see any place where self.canvas.draw is called in the code1 version. Also, when I resize the figure, the background region changes, so the plot gets messed up as I have noticed before with this method. Does anyone know a good way to recapture a clean background, in particular when the image is resized? It's a good question. There is no explicit fig.canvas.draw in the code1 example, but there is an implicit one, since the relevant function calls (draw_artist, restore_region and blit) occur in the wx OnTimer method. These things are GUI dependent, but stuff that happens in the idle hander or timer handler of GUI toolkits often happen after the initial mpl draw.
