I'm looking for a library that allows me to visualize data under X11 screen, for instance as a pie chart or as a bar chart. I seem to recall that something like that was available for the GTK toolkit, but has this library been ported to Haskell? Or any other library?
I think, the GTK+ widget that you are referring to is GtkPlot from the GTK+Extra set http://gtkextra.sourceforge.net/ To my knowledge, there is no Haskell binding for it yet. However, it is possible to extend the existing GTK+ binding for Haskell http://www.cse.unsw.edu.au/~chak/haskell/gtk/ with extra widgets (there already exist some such extension in the ext/ directory of the package). I am generally happy to include such extensions into the main distribution and to provide help with coding them. Cheers, Manuel
