matplotlib-devel Mailing List for matplotlib

Dear Daishi,
I appreciate that you're trying to make life easier for Fink users, but 
I don't thing the Right Thing on an OS X platform involves 
automatically determining if a user has Fink installed and then using 
it. Fink is, to some degree, a different platform than stock OS X, and 
even if one has Fink installed, it doesn't mean that one wants to build 
one's Python extensions against it. (Even if one has a subdirectory of 
/sw in sys.path.)
I would propose one or both of these solutions: 1) a non-automatic 
"use_fink" flag in the setup(ext) file and/or as a command line switch. 
2) building (and maintaining!) a python-matplotlib Fink package.
Cheers!
Andrew

re: nav toolbar
Works for me with my fink build of the latest CVS matplotlib.
On the other hand, I'm still having problems building with fink
out of the box. I'm attaching my latest setupext.py. It includes
a hack to distinguish between vanilla darwin vs finked.
Finally, I've noticed that under WX the GUI thread doesn't
terminate when the close button is pressed.

Yes. I'll fix it.

This is a bug (clearly!). I didn't catch it in my tests because it
only arises when you get an OSError on a win32 registry call, which I
never got. I believe Paul lifted this section of the code from
ttfquery. For a quick fix, in the win32InstalledFonts function, try
replacing
 try:
 local = _winreg.OpenKey(_winreg.HKEY_LOCAL_MACHINE, fontdir)
 except OSError:
 pass
with 
 try:
 local = _winreg.OpenKey(_winreg.HKEY_LOCAL_MACHINE, fontdir)
 except OSError:
 continue
and let me know how things go.
Paul, is the continue the correct behavior here?
Thanks for the report,
JDH

I just uninstalled the 0.53b release and installed 0.53
There's still a problem on my Win98 system, but now it seems related to the
new font manager:

What's new in matplotlib 0.53
Improved font manager and support
 Paul Barrett has thoroughly overhauled font support. FontTools and
 ttfquery are no longer required for font finding as matplotlib now
 has a completely freestanding freetype2 implementation and font
 finder. Among other things, this should enable you to specify fonts
 in your scripts and matplotlibrc file and generate consistent
 figures across backends and operating systems. The font finder
 algorithm and implementation are based on the W3C standard
 http://www.w3.org/TR/1999/REC-CSS1-19990111.
 See the font manager module documentation, the fonts documentation
 http://matplotlib.sf.net/fonts.html and the updated .matplotlibrc
 file for more details; please update your .matplotlibrc. Thanks
 Paul!
Backend WXAgg
 Antigrain rendering to wxpython applications and figure windows. Now
 wx users have access to all the latest matplotlib functionality,
 including mathtext, antialised drawing, alpha blending and image
 support.
Major and minor ticks
 Full support for major and minor ticks with a bevy of more
 intelligent tick locators supplied in the ticker module. Fully
 customizable and user definable tick locators and formatters. See
 major_minor_demo1.py and major_minor_demo2.py. The default tick
 labeler is much more intelligent in choosing good tick locations.
 See http://matplotlib.sf.net/matplotlib.ticker.html
Date plots
 A new command a plot_date command for plotting date dependent data;
 see http://matplotlib.sf.net/screenshots.html#date_demo. Converters
 supplied in the dates module allow you to work with a variety of
 datetime instances. Custom date locators and formatters allow you to
 place major and minor ticks by minute, hour, weekday, month, year,
 etc, and use strftime format strings to format the ticks. See
 examples date_demo1.py and date_demo2.py. The dates documentation
 provides an overview and guide to with dates -
 see http://matplotlib.sf.net/matplotlib.dates.html.
Ported image support to numarray and postscript backend
 The image module now works with Numeric or numarray, and now works
 in the postscript backend as well as GTKAgg, TkAgg, WXAgg, Agg, and
 GTK. Thanks to Todd Miller for the PS work!
Changes to matplotlibrc
 Many features added to the default config file for font support,
 tkagg windowing in win32, and more. Please use the new file at
 http://matplotlib.sf.net/.matplotlibrc. By default, the installer
 will overwrite the existing file in the install path, so if you want
 to preserve your's, please move it to your HOME dir and set the
 environment variable if necessary.
load and save commands
 Helper functions for loading and saving ASCII arrays. See load and
 save in the matlab interface.
Two scales on the same axes
 Added some features to the axis and ticks to allow two plots with
 different scales on the "same" axes with different scales, ticks and
 labels on the left and right side of the x axis. To see why same is
 quoted, see examples/two_scales.py.
finance module
 The finance module includes a function to fetch quotes from yahoo,
 to draw candlestick plots, and to draw vertical line plots for
 high-low range with open-close ticks to the left and right. I'm
 hoping that user contributions will make up the bulk of this module
 since I'm not a finance guy! See
 http://matplotlib.sf.net/screenshots.html#date_demo.

John,
I'd like to request that the matplotlib/examples are made into
executable scripts by adding 
#!/usr/bin/env python
as first line for all examples. This benefits Unix users and has no
effect (as far as I know) for non-Unix users.
It can be done for all scripts from the command line with a 'sh' style
shell, using something like:
cd examples
echo "#!/usr/bin/env python" >/tmp/header
for file in *.py; do
 mv $file ${file}.old
 cat /tmp/header ${file}.old > $file
done
# check the new files look OK and delete *.old
Regards
Steve

I recommend removing the "Close the Figure" button from the toolbar.
It just destroys the widget / exits the program, which you can already
do by clicking the close button that the window manager provides.
The GNOME Human Interface Guidelines, Chapter 5 Toolbars, says
"Don't add buttons for Help, Close or Quit to your toolbar by default,
as these are rarely used and the space is better used for more useful
controls."
http://developer.gnome.org/projects/gup/hig/1.0/toolbars.html
This reference is for GNOME/GTK+ applications and other windowing
environments will have their own guidelines, but I think they agree that
Close/Quit buttons on toolbars are not needed.
Check your own system - run some applications you use that have toolbars
and check if there is a quit button, and even if there is would it cause
a problem if it wasn't there?
Steve

On my OS X machine, the navigation toolbar is not showing up in
backend_wx, though the other widgets (eg axes selector, status bar)
seem to work fine. If anyone has any ideas, please let me know.
