How do I draw different types of lines on gnuplot? I got to draw different colors. My script joins several files and I think it is why the lines are not dash. Only two of four are dashed. Thanks Felipe

The dash type of a linestyle
is given by the linetype
, which does also select the line color unless you explicitely set an other one with linecolor
.
However, the support for dashed lines depends on the selected terminal:
png
(uses libgd
)pngcairo
, support dashed lines, but it is disables by default. To enable it, use set termoption dashed
, or set terminal pngcairo dashed ...
.linetype
, use the test
command:Running
set terminal pngcairo dashed
set output 'test.png'
test
set output
gives:
whereas, the postscript
terminal shows different dash patterns:
set terminal postscript eps color colortext
set output 'test.eps'
test
set output
Starting with version 5.0 the following changes related to linetypes, dash patterns and line colors are introduced:
A new dashtype
parameter was introduced:
To get the predefined dash patterns, use e.g.
plot x dashtype 2
You can also specify custom dash patterns like
plot x dashtype (3,5,10,5),\
2*x dashtype '.-_'
The terminal options dashed
and solid
are ignored. By default all lines are solid. To change them to dashed, use e.g.
set for [i=1:8] linetype i dashtype i
The default set of line colors was changed. You can select between three different color sets with set colorsequence default|podo|classic
