After ssh -Y foo@bar.com, is it possible to run gnuplot and open the output picture on local machine? Here is what I get now:

$ echo $TERM
xterm-256color
$ echo $DISPLAY

$ gnuplot

        gnuplot home:     http://www.gnuplot.info
        faq, bugs, etc:   type "help FAQ"
        immediate help:   type "help"  (plot window: hit 'h')

Terminal type set to 'unknown'
gnuplot> plot sin(x)
gnuplot>

Nothing appears. If I set terminal png, I did get something back but not in a opened window as a picture:

gnuplot> set terminal png
Terminal type set to 'png'

  • Post what do the ssh -Y foo@bar.com print after authentication. The X11 forwarding probably failed, since you don't have $DISPLAY variable. – Jakuje Oct 28 '15 at 19:43
  • @Jakuje see above – wlnirvana Oct 28 '15 at 19:50
  • so no failure? One basic question. Do you have Xorg installed on the remote system? – Jakuje Oct 28 '15 at 20:42
  • ^^^ +1, you will also need gnuplot-x11 to be installed rather than plain gnuplot I think; then you can run show term from the gnuplot command line to see if it's actually set to a GUI output type; set term should list the available types (look for the x11 or wx terms) – steeldriver Oct 28 '15 at 21:07
  • It turns out that xorg is not installed on my local cygwin. I just reboot to my linux and $DISPLAY is vm-bar.com:12.0. Although I can start gvim now, gnuplot still says terminal unknow. set term has no x11 or wx or qt option. I suppose that might be the problem? – wlnirvana Oct 28 '15 at 21:40
