Thanks; good idea - but nope.
I'd file a report to EasyPlot, but not sure where to do that.
Older discussions on this issue note that there is a "persist" option for
gnuplot, but I didn't yet see how to pass that to try it.
-----Original Message-----
My first hunch was that, since the program ends right after plotting, it cleans
up the plot window and exits. But trying it on an X11 system, I got a
persistent window despite the program exiting. That may be a difference between
Unix and Windows child process handling; I don't have a Windows machine handy
right now to test, but you could try this:
main = do
plot Windows $ Data2D [Title "Demo Title"] [] tData
_ <- getLine
return ()
If that doesn't fix it, my only guess is there's either a difference between
the Unix and Windows versions of gnuplot, or a bug in easyplot's Windows
handling.

Maybe you could try with plot'

What I meant was:
import Graphics.EasyPlot
tData = [ (1,2), (2,3), (3,1), (4,5), (5,3), (6,1) ]
main = do plot' [Interactive] Windows $ Data2D [Title "Demo Title"] []
tData
this should work, but it keeps gnuplot open (so you have to type "quit" on
the terminal).
(I think there is a difference between the Unix and Windows versions for
Gnuplot; I had the same problem when I used gnuplot in C programs)
