Yes okay, I=B4m just more confortable with using package which come with
instalador, especially in this case because I need the program to run on
windows. On linux, I can prepare the package (but it takes some time)

Okay, maybe but right know it's running perfectly and I have a panel that I
can reuse easily in any wxpython application! (and I was willing to
understand)

oh yes, exactly that!

so that I can call the handler from other code as well.

Hi all,

I just had to do a re0install, and tried the packages for python 2.4 on 
pythonmac.org

the matplotlib package:

matplotlib-0.87.7-py2.4-macosx10.4.dmg

Doesn't seem to work with the wxPython package:

wxPython2.6-osx-unicode-2.6.3.3-universal10.4-py2.4.dmg

What version was it built against?

What version of numpy, while I'm at it.

We should try to make sure all the stuff at pythonmac is compatible.

-Chris

You don't need an installer -- it's a simple python-only module. It 
includes a setup.py file:

python setup.py install

should do it.

wxMPL would have been faster -- and it still might be a good idea - 
there's some good stuff in there.

A wxTimer uses the standard wx event system to do it's stuff. Every time 
an event calls a handler, it passes in the event itself, which often has 
useful information in it (like the coordinates of a mouse, event, for 
instance), so event handlers usually have a signature like:

def MyCallback(self, event):


I often use:

def MyCallback(self, event=None):

so that I can call the handler from other code as well.

exactly -- you're getting a timer event object.

Set the zorder of the PolyCollection (what scatter uses) to be higher
than the zorder of the Polygon

  col = ax.scatter(x,y, color="b", s=150, marker="s", alpha=0.2, zorder=Polygon.zorder+1)

Hello, 

How to set linewidth for bars and legend rectangle separately? I need
thick edge of bars but the rectangle line in legend could have the
linewidth set to 0.5. In matplotlibrc file I have:
patch.linewidth   	: 2.0

Another question concerns the numbers of x-axis and y-axis. I the left
bottom corner the numbers of both axes overlap. I would like to have the
numbers of y-axis placed a little bit to the left. How to do it?

Regards,
SK

Hi,

how can I draw the scatter squares in front of the Polygon? 

from pylab import *
x,y = zip(*randn(10,2))
ax=subplot(111)
xRange=(-10,10)
yRange=xRange
poly = Polygon([(xRange[0], yRange[0]), (xRange[0], yRange[1]), (0, yRange[1]), (0, yRange[0])], 
           facecolor='0.7', edgecolor='0.6', alpha=0.0)
ax.add_patch(poly)
ax.scatter(x,y, color="b", s=150, marker="s", alpha=0.2)
show()

Regards,
wr

The subplot comma notation problem I was having seems to have gone away in
the latest Ubuntu distribution, which includes MPL 0.87-5.

Thanks,
