Has anyone got some code for drawing charts? I don't mean graphs of functions, ala
http://dockerz.net/twd/HaskellCharts ... I would like something that can generate PNGs in memory, i.e. not directly to a file.
The library at the above URL supports a range of backends through the (nice to use) cairo graphics API. In memory images are supported. Also, it's by no means just graphs of functions - that just happens to be several of the demos.
I'd like 2D pie charts, bar charts and something like a google-o-meter.
An the moment it does line charts and a few variants of these. I'll add pie and bar charts when I need them - patches in the meantime gratefully accepted. Tim
