I am using gnuplot under ubuntu 12.04. When i type in terminal :
Terminal Type Set to 'unknown'
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? I have already installed gnuplot-x11. It is showing that the latest version is installed.
set terminal png
and `set output filename.png'?
