Thanks Jon for your help.
  I finally managed to solve this by explicitly mentioning the path in the
gnuplot-program as C:\Program Files (x86)\gnuplot\bin\gnuplot.exe

However, gnuplot hangs and does nothing after that though.

Thanks again
Bala

Bala,

Does `(executable-find "gnuplot")` return the path to the executable?  If
not it might not be properly set in Windows (and/or Emacs was not restarted
with the updated environment variables).
