[Matplotlib-users] Rendering a plot into a variable?

[Steve B. <st...@ru...>]

I am using pylab in a web application server (TurboGears/CherryPy). 

I need to be able to render a plot (actually a pie) in png, jpg, or gif 
format directly into a variable that I can return to the application 
server.  I'm currently using the rather ugly method of writing to a temp 
file and then reading it back in and returning the data.  Is there a way 
to do this completely in memory?

Thanks,
Steve Bergman
