Width gnuplot 5.2 I wish to generate plots into png files.

I succeed in changing line colors and widths for continuous lines. However not to generate dotted lines.

Is this not implemented for png outputs or what am i missing?

Does "dashtype"

plot x**2 w l dt 0

not give what you´re looking for? You see more dashtypes with the
"test" command.

Yes it works for dt -1 and dt 0. However still not for dt 1 to dt 19 of the rightmost part of the "test" command.

Which terminal do you use? The pngcairo terminal is the good one for png output.


set term pngcairo size 1200,900
set out 'dt.png'
plot for [i=1:20] sin(x+i) w l dt i t "dt".i
set out

Works fine.

Thank you all who contributed.

Works fine with datatype 1 to 5. dt 1 to 5 lines are repeated, with other colors, for dt 6 to 20.

How to generate lines with symbols according to the right hand side of the "test" output?

There are only 5 different dashtypes predefined. You can add more by
your own. See "help dashtype".

Examples:
plot f(x) dt 3 # use terminal-specific dash pattern 3
plot f(x) dt ".. " # construct a dash pattern on the spot
plot f(x) dt (2,5,2,15) # numerical representation of the same pattern
set dashtype 11 (2,4,4,7) # define new dashtype to be called by index
plot f(x) dt 11 # plot using our new dashtype
