[py-rrdtool-users] generate graphs directly to a buffer

[Clemens Weninger]

Hello everybody,
I am trying to generate dynamic graphs with the python bindings and display 
them directly on a web page. I would like to generate the graphs directly in a 
buffer and not take the detour of saving them to disk.
If I use

#!/usr/bin/python
import rrdtool
rrdtool.graph(('-', <options>)

I get the output directly into the stdout, but I found no way to redirect the 
output in any way. Is it even possible to use something like  cStringIO to get 
the output in a buffer I can access?
If it is not possible at the moment is is possible to modify the bindings to 
include this functionality without too much work?

Any ideas are appreciated

Thanks
