change linestyle and pointstyle under gnuplot

[Stefan Pofahl]

Hello,

I work under win32 (octave vers.2.1.73)
and I want to change the line width.
I tried:

__gnuplot_set__ style line 2 lt -1 lw 3 pt 3 ps 5.0;

with no succes and I don't know, if I made a mistake,
I thing that the line above should change linewith
from 1 to 3 on the second line, but it is not working :-(

Here is my workaround.

Perhaps there is a more elegant method.

Kindest Regards,

Stefan
