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.

A very simple test program with Graphics.EasyPlot, flashes up a window, but too fast to see it. There are several old posts on this issue with gnuplot, but I haven’t seen any current solutions.

 

Example:

import Graphics.EasyPlot

 

tData = [ (1,2), (2,3), (3,1), (4,5), (5,3), (6,1) ]

 

main = do plot Windows $ Data2D [Title "Demo Title"] [] tData
