Ubuntu – gnuplot not showing the graph window

gnuplot

I am using gnuplot under ubuntu 12.10. When i type in terminal :

gnuplot> plot sin(x)

it only shows next step:

gnuplot>

but it doesn't show the graph plotting windows. What can I do to find the problem?

You might be missing gnuplot-x11. Try to install it. In the commandline, do this:

sudo apt-get install gnuplot-x11

The problem seems to be that "unknown".

Here says the same as you said you have, install gnuplot-x11 : Not able to get graphs on screen with gnuplot

Maybe trying to do a reconfiguration of the package?

sudo apt-get purge gnuplot*
sudo apt-get install gnuplot-x11

I could solve my problem by downloading Xming on my Windows system, so that linux can access X11 The qt terminal works well in this condition.

Thanks for the help !
