Jump to: navigation, search

When using the X11 server's default settings, Gnuplot's X11 terminal does not support different linestyles. Thus, all line plots have solid line types, independent of the "linestyle" specified. To enable support for the various linestyles, add the lines below to your ~/.Xdefaults.

! gnuplot settings
gnuplot*dashed: on
gnuplot*borderDashes:   0
gnuplot*axisDashes:    16
gnuplot*line1Dashes:    0
gnuplot*line2Dashes:   42
gnuplot*line3Dashes:   13
gnuplot*line4Dashes:   44
gnuplot*line5Dashes:   15
gnuplot*line6Dashes: 4441
gnuplot*line7Dashes:   42
gnuplot*line8Dashes:   13

To enable these settings, type the following command at the shell prompt.

xrdb -merge .Xdefaults

To avoid having to type this command repeatedly, the command may be placed in your shell script resource file, ~/.profile for example.
