For the postscript terminal the default mode is already dashed
, which you see when you type your set terminal
line in the interactive gnuplot-terminal:
gnuplot> set terminal postscript eps size 8.5cm, 7cm enhanced color font 'Helvetica,10'
Terminal type set to 'postscript'
Options are 'eps enhanced defaultplex \
leveldefault color colortext \
dashed dashlength 1.0 linewidth 1.0 butt noclip \
nobackground \
palfuncparam 2000,0.003 \
size 8.50cm, 7.00cm "Helvetica" 10 fontscale 1.0 '
Otherwise, in solid
mode, the only dashed linetype is lt -1
.
The above message also tells you, how you can change the dashlength. Up to version 4.6, the only way to change the dashlength is to use the dashlength
option, e.g. with
set termoption dashlength 1.5
Unfortunately, this affects all line types.
Only 5.0 version supports arbitrary, configurable dash patterns. Note also, that in version 5 the dashlength depends on the selected line width.
