Hello, I've used the gnuplot package http://hackage.haskell.org/package/gnuplot before with great satisfaction. Now I have a new computer (a Lenovo T400 with ubuntu 9.10) and I have a problem. After I make a plot in ghci, using a command such as plotFunc [] [0.0,0.1..10.0] cos shown below, the keyboard no longer echos my input to ghci. ghci will still do what I ask, as in computing 3+4 below, but I could not see the "3+4" until after I hit return. This is gnuplot 0.3.4. Could anyone suggest an idea? Thanks, Scott walck@walck-nsf:~/courses/phy261/code$ gnuplot --version gnuplot 4.2 patchlevel 5 walck@walck-nsf:~/courses/phy261/code$ ghci GHCi, version 6.12.1: http://www.haskell.org/ghc/ :? for help Loading package ghc-prim ... linking ... done.
