I was going to list the possible packages but found too many... so
search for "chart" and "plot" on Hackage:
http://hackage.haskell.org/package/

In particular, the Chart, plot and gnuplot libraries probably do what
you want (or at least a subset).

Thanks!
I tried gnuplot:

GHCi, version 7.0.3: http://www.haskell.org/ghc/  :? for help
Loading package ghc-prim ... linking ... done.

Demo.hs:25:18:
    Could not find module `Paths_gnuplot':

Where to get `Paths_gnuplot': module?
