Then I managed to install splot and timeplot. I then tried to use Chart to draw a simple chart, following http://hackage.haskell.org/packages/archive/Chart/0.16/doc/html/Graphics-Ren... and it hang forever with a CPU at 100%.
As the author of the Chart library, I'm sorry to say "I don't know". Chart is developed under linux, and I do occasional testing under osx, but I don't use windows at all. Chart is a pure haskell library sitting over cairo, so it is most likely a cairo problem rather than a chart one, but I realise this doesn't help you.
Do the examples that come with the haskell binding to cairo work for you?
Windows and gtk continues to be problematic for many users. I'd love to see an alternative backend for the chart library, but I would need a graphics API that installs easily under windows, osx and linux, and provides good access to fonts and font metrics. Any suggestions?
Good access to fonts and font metrics is the kicker. Otherwise I'd say to switch to using diagrams as a backend, hence getting a whole bunch of actual backends for free. I would love to see development of some good Haskell font packages -- maybe it would even make a good GSoC project? Unfortunately I don't know enough about it to even know what would be involved, or how much work it would be. -Brent
