Message: [QUOTE="Jan Danielsson, post: 2056386"] Hello all, I have written a program which takes some data from a postgresql database, and via mod_python outputs it as tables on a web site. Now I would like to present these tables as graphs, which matplotlib can do. But in order to properly display these graphs on the web page, I need to return the image data, like so: def barchart(req, params): some_format = matplotlib.generate_fancy_graph(params) png_buf = make_png_buffer(some_format) return png_buf Is this possible? If so -- how? -- Kind regards, Jan Danielsson ------------ And now a word from our sponsor ------------------ For a quality usenet news server, try DNEWS, easy to install, fast, efficient and reliable.
