You need to install matplotlib from the svn trunk.

Is there an minimal example file available showing how to activate this new
plot toolbar ?

changing the backend to Qt4Agg apparently is not sufficient.

I thought so until I put in cm.jet[255] and it maxed out. The
granularity of the 255 colours that I get from exporting the RGB
values is more than enough for the ranges of data I use. So I am happy
with that.

I am using PIL because I plan to plug in a Tkinter interface which can
directly accept PIL image instances.

Hi all --

I'm new to Matplotlib, and it looks like a great project, but I'm having
trouble figuring out one thing.

I would like to draw a pie chart, but have each wedge appear to have
thickness.  I see from the examples and the docs that it is possible to draw
a wedge in relief so that it appears to cast a shadow, but I don't see how
to make it look something like this.  Pardon my bad ascii art. :)

Is there a way to do this?

Thanks,

I am running the 6.01 enthought 64 python package.
I do the development inside of wingide
if I run code inside of the wingide pythonshell, do a simple plot, I have to
type show().

If I try to save the plot, I get the dialog but can not enter text into the
file name. I can select an existing file and it will load the name into the
text box but I can not edit it. Another strange part about this is that if I
select an existing image.jpg and then hit save. I does not over write this
file since it defaults to a png file. The plot gets saved as a image.png.

Not sure it this is the right forum to post this, guidance or help would be
appreciated.
