[Gnuplot-info] streamline with gnuplot ?

[Dellacherie S. <del...@CR...>]

Hello,

To obtain streamline with gnuplot, I use the command lines :

set xrange [-1:1]
set yrange [-1:1]
set arrow from 0,0 to 0.5,0.5
plot (0)
unset arrow
set xrange [*:*]
set yrange [*:*]

The problem is that I do not know how to do without the command line=20
"plot(0)".

Indeed, without this command, I cannot see the arrow on my x11 terminal.

What is the right way to obtain the arrows on my x11 terminal (i.e.=20
without "plot(0)") ?

Thank you for your help.
