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. -- Eugene Kirpichov Principal Engineer, Mirantis Inc. http://www.mirantis.com/ Editor, http://fprog.ru/
