Hello,

Please advise on Haskell 2D plotting libraries to generate plots, histograms, power spectra, bar charts, errorcharts, scatterplots, etc, similar to what Matplotlib does: http://matplotlib.sourceforge.net/

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).

$ cd gnuplot-0.4.2 $ cabal install # this generates the Paths_gnuplot module $ ghci

Yes, you must install the package before loading Demo into GHCi, since the package contains a data file that the Demo wants to load.

Currently I am trying to interface to gnuplot's histogram feature.

You may also to subscribe to http://projects.haskell.org/cgi-bin/mailman/listinfo/gnuplot

Thanks! So, if I got this right, I should run: 'cabal install -fbuildExamples gnuplot' from gnuplot source root folder? Yet first I need to build gnupolt for MacOSX and Win32 that I both use. Ok, I'll give it a try...

You can either get the gnuplot tarball from Hackage, unpack it, and then within the directory do "cabal install -fbuildExamples" (assuming you want the examples). Or else you can just do "cabal install -fbuildExamples gnuplot" from anywhere and cabal-install will download it, unpack it, build it, install it and then remove the unpacked tarball.

I got the gnuplot tarball from Hackage, unpacked it, and then within the directory do "cabal install -fbuildExamples". That's what I get (see below). What else should I do to install gnuplot?

Do you really want to compile the Demo (with ghc)? It is already compiled if 'cabal install -fbuildExamples' was successful. Maybe you want to run 'ghci' for interactive tests. But you need to tell 'ghci' the path to the Paths module. 'make ghci-demo' should call GHCi with the right options on Linux:

$ ghci -Wall -i:src:dist/build/autogen:execute/tmp src/Demo.hs

Did I already advertise the gnuplot mailing list? http://projects.haskell.org/cgi-bin/mailman/listinfo/gnuplot/

Yes, you did, thanks. Yet, please allow me to ask a few more questions here, before I subscribe to gnuplot list. I am really short on time - must have some plots for demo next Monday ( 1) Can current version of gnuplot draw histograms? I need these first of all. 2) It seems that "$ ghci -Wall -i:src:dist/build/autogen:execute/tmp src/Demo.hs" works on Mac OSX, yet I can't make it produce any output directly on screen. How to generate output and display it immediately in an output window?
