matplotlib-users Mailing List for matplotlib

Ok, I know what the problem is.  I was using a sample
setup.py posted by Stef and in his setup, he created a
"mpl-data" subdirectory under "dist" to store all of
the data files use by matplotlib.  That's why
matplotlib couldn't find it without a set statement. 
After changing the name to "matplotlibdata",
everything works.

I also made changes to every one of the matplotlibrc
file I found in the installed copy of matplotlib to
invoke WXAgg - instead of TkAgg.

So for completeless, may be this will benefit other
matplotlib users, here's my py2exe script - tested
using python 2.3, latest wxpython and so forth.

Let say you wish to create an exe of the sample
multicolor.py program.  Place multicolor.py in a
test\multicolor directory, and a copy of the following
script, have py2exe installed, and then just run it. 
You will end up with a dist subdirectory under
test\multicolor and that's where you'll find
multicolor.exe.

Thanks Michael!

I'm new to this but I'm still kicking myself for not spotting it.  Just
what I was looking for.

It sounds like what you want is to use the "shared axis" functionality.

You shouldn't need to do this.  Note in matplotlib.__init__.py, it looks 
at a different folder if it is frozen by py2exe or py2app or ...:
    # py2exe zips pure python, so still need special check
    if getattr(sys,'frozen',None):
        path = os.path.join(os.path.split(sys.path[0])[0], 'matplotlibdata')

So, if you use the sample setup.py I posted a while ago here and on the 
wxPython list it will create the matplotlibdata folder in your 
distribution (basically a copy of your mpl-data folder) folder.

Yeah -- the hinting doesn't seem work very well with the STIX fonts.  I 
may need to expose an option in the font backend to turn hinting off.

Thanks for the report,

Just an idea: Maybe you could also auto cycle between dash types if only 
the colour and not the dash type is specified in a plot command. The 
gnuplot default would be one model, or the predefined patterns in 
CorelDraw or Inkscape etc. Personally I don't see this as a high 
priority though.

I would like to plot two or three graphs as subplots in a figure and
control the axes such that when one graph is zoomed the others are
adjusted too.  I was hoping there would be a notification mechanism
which would allow me to catch a rescaling of one subplot and redraw the
others in step.  Can anyone suggest a method of doing this?

I *finally* got this to work!!!  

Thanks to Werner's message, I found the culpit:  the
matplotlibrc file copied to the dist directory
contains the TkAgg backend.  All I had to do is to
change *that* file to say:

backend      : WXAgg

Note that it's not the matplotlibrc in the installed
copy - but the one in the resulting dist directory.

In addition, I have to do a:

   set MATPLOTLIBDATA=.\mpl-data

before I start the exe file.  I don't know why this is
necessary because the code for _get_data_path appears
to look at that directory by default but if I don't
set this, it can't find the data files.

In any event, it works now - after bumping head for 2
weeks!

Thanks everybody.

I am under the impression that as of mpl 0.9x there is NO specific
version dependency for wxPython.  I believe there was some optimization
code which forced a dependency on wxPython 2.6 Unicode for the wxAgg
backend.

I think this is your problem, I have:

numerix      : numpy  # numpy, Numeric or numarray


Hope this gets it cleared.

I haven't tried it with 0.91.x but with 0.90 I used a matplotlib exe
installer for Windows and I can create a distribution of my application
with py2exe which does NOT contain tkinter.

That dll should no longer be needed by matplotlib.  Obviously if you use
a wxPython build you will get the it, i.e. I am on 2.8 so I have a bunch
of  "wxmsw26uh???.dll" files in my dist folder.

There was another message from Stef which might be the explanation, the
default matplotlibrc file is defining TKAgg as the default backend, so
change it to the following:

backend      : WXAgg
numerix      : numpy  # numpy, Numeric or numarray


Werner

Michael,

I am referring to the fact that there are no Windows
binaries provided for Python 2.3.  If I simply copy
the matplotlib directory over to Python23, py2exe will
get confused.

I have no clue how to build it for Python23.  I don't
even have any C compiler.
