Jeff, 
This "_r" command seems not work well. Let me show you the full
line of that color map plot,
 --------------------------------------
contourf(X, Y, Z, v1, cmap=cm.pink)
 -------------------------------------- 
By the way, Jeff, do you know how to make the cmap explicitly defined,
like in GNUPLOT,
 ----------------------------------------------------------------
set palette defined (0.004 "white", 0.17 "brown", 0.28 "black")
 ---------------------------------------------------------------- 
Thank you so much!

Hi,
I'm wondering how to use matplotlib to 
plot on axes that intersect at the 
origin, as in the following picture:

 |(0,0)

Any help will be appreciated

Teng: Simply append '_r' to the colormap name to get the colors 
reversed (e.g. cmap = pylab.cm.hot_r instead of pylab.cm.hot).

Hello, I have a quick question for you. 
I was trying to make a color and contour plot. But the problem is that
the matplot defaults the colors from the dark to light for the contour
values from minimum to maximum, is there any way or commands to reverse
this order? I mean the dark color for maximum value and light color for
minimum. 
Thank you so much!

See the chapter on mathtext on page 32 in the user guide:

That is described on page 52 in the user guide (see listing 6.1 for an 
example).
Hope this helps.

Hi All,
I'm trying to respond to double-click events on axis labels and tick
labels. I'm using the wxAgg backend, and matplotlib directly, not
through pylab. The matplotlib panels are wrapped into a bigger program.
Based on an thread between Andrea Gavana and Chris Barker back in Feb
06, I hacked a double-click event into backend_bases.py and
backend_wx.py. This seems to work as expected; I can capture the double
click events without any problem. Now for capturing pick events, the
built-in pick function seems to rely on the selection being "inaxes" so
I borrowed heavily from the object_picker.py demo to capture selecting
the tick labels or the axis labels.
My concern is that I'm reinventing the wheel. Being able to capture
picks of the various labels seems like a natural thing to want to do
(e.g. for modifying font properties, display format, etc). Is there an
easier (erm, and better!) way to accomplish what I've done?
Thanks,
Anthony.
