Hi Zope users. Please excuse another dumb question. I wish to produce some dynamic graphs inside Zope to display biological data. I am using pychart, this is clean and IMO has the best looking output for least amount of effort. I can produce graphics by writing a .png file to disk, and then reading it back to return to the client as RESPONSE. This is not optimal - why do I bother writing something to disk, to read it again to delete it? I have had a play using cStringIO, but cannot make this work. Does anyone have any pointers or examples of how I can create graphics in PyChart and display them using Zope without needing to write binary intermediates to the filesystem?
