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?

This is what I get:

~/wks/haskell-wks/gnuplot/gnuplot-0.4.2>ghci -Wall
-i:src:dist/build/autogen:execute/tmp src/Demo.hs
GHCi, version 6.12.3: http://www.haskell.org/ghc/  :? for help
