The function "clabel" does not allow the use of formatters for the label;
this small patch enables their use, so that one can pass in any subclass of
ticker.Formatter in the 'fmt' argument.

Replace the following in contour.py:

   def get_text(self, lev, fmt):
       "get the text of the label"
       if cbook.is_string_like(lev):
           return lev
       else:
           if isinstance(fmt,dict):
               return fmt[lev]
           else:
               return fmt%lev

With the following:

   def get_text(self, lev, fmt):
       "get the text of the label"
       if cbook.is_string_like(lev):
           return lev
       else:
           if isinstance(fmt,dict):
               return fmt[lev]
           elif isinstance(fmt,ticker.Formatter):
               return fmt(lev)
           else:
               return fmt%lev


As you can see, there is only a two line change, but it does enable
formatters.  Perhaps one of the devs can put this in?

No, it was too late to save me from a headache :-(

But this indeed fixed my segmentation fault too, so thanks lot!

(Running OpenSuse 11.2; Python segfaulted on a mere "import
matplotlib.pyplot as plt" statement)

Can someone please update the system requirements / dependencies for
matplotlib, or fix this in the source code?

Regards,

Diederik

Hello,

I am trying to change the default font by adding the following lines
to the matplotlibrc file:

## FONT
font.family : serif
font.serif : Palatino

However, I get the following error.

/Library/Frameworks/Python.framework/Versions/6.3/lib/python2.6/site-packages/matplotlib/font_manager.py:1242:
UserWarning: findfont: Font family ['serif'] not found. Falling back
to Bitstream Vera Sans
  (prop.get_family(), self.defaultFamily[fontext]))

If I just use:

font.family : serif

I get a serif font (that is not Palatino). I certainly have Palatino
on my machine (Mac OS X 10.5.8).
Am I doing something wrong? If I want all text to be some font, is
there a way to change it in matplotlibrc file?

Thanks for your help.

You likely have the 32 bit version of Python 2.6 installed. You need to 
download and install matplotlib-1.0.1.win32-py2.6.exe.

Windows Vista
Python 2.6

I downloaded matplotlib-1.0.1.win-amd64-py2.6.exe from
http://sourceforge.net/projects/matplotlib/files/matplotlib/matplotlib-1.0.1/,
but I get "Python version 2.6 required, which was not found in the
registry".

I do have Python 2.6, but its folder is C:\Python26. What to do?

Thanks,

Hi,

If I want to specify the color_cycle for plot lines, I can use the
following line in a matplotlibrc file:

axes.color_cycle : b, g, r, c

Is there a similar specification that can be used for cycling through
markers? Something like:

lines.marker_cycle : s, o, x, +

Thank you.

Thomas and Goyo,

Thanks for the answers. I am fine with them being coverted to ints. In
fact, my ax.set_ylim(bottom=0, top=6000) contains ints and I don't
understand why they are converted to floats. I was thinking that there
is perhaps another (more correct) way to set tick values. I will
either use Thomas' approach or Goyo's.

Thanks again.
