[Haskell-cafe] Drawing charts over a lot of data

[Eugene Kirpichov]

Hi cafe,

Are there any (possibly unfinished?) libraries dedicated to drawing charts
over large amounts of data? I mean, such amounts that you don't want to
store the whole set of input data in memory and instead you prefer to do
one or a few passes over the input, calling the library's drawing functions
for each data point.

I'm currently using the excellent Chart package
http://hackage.haskell.org/package/Chart , but it seems to require quite a
bit of work to become usable in this mode (I haven't looked really deep
yet).

So, I'd be happy if someone pointed me to an existing package (I didn't
find one on hackage) or if someone expressed interest in making Chart avoid
having the whole input in memory.
