问题
I am wondering if gnuplot offers more hatched patterns than those 8 patterns which you see when typing "test" (e.g. in wxt terminal)
Maybe there are more than 8 fill patterns? ...apparently not, as the code below shows... I'm not talking about patterns combined with different colors, I just mean the type of patterns.
I was hoping that you can realize, for example horizontally or vertically hatched patterns. Maybe even set the distance between the hatch lines or even set the angle. Maybe you can?
### hatched pattern fill
reset session
set colorsequence classic
N = 28
set samples N
set table $Data
plot [1:N] x
unset table
plot for [i=1:N] $Data u 1:1:(1) every ::i-1::i-1 with boxes fs pattern i not
### end of code
