[robijf <ro...@gm...>]

Hello to everyone!


I would like to plot two horizontal lines and two vertical lines, something
like this:

|                |       |
|__________|____|__________

both with plot and splot command (for a 3D style). Fact is that I am new to
gnuplot (only used it for a couple of weeks), and I cannot figure out how it
really works. I tried plotting it by using a data file, with no luck
whatsoever.

I appreciate any help.

Thanks in advance.

You want to use

set arrow from x0,y0 to x1,y1 nohead
plot 1/0

And:

help set arrow

will explain arrows for you.

I've tried the following:


set xr[0:50]
set yr[0:50]
set zr[0:50]
set arrow from x0,y0,z0 to x1,y1,z1 nohead
plot 1/0


and the result is this:

Initial values:

x0=25
y0=15
z0=20

x1=25
y1=15
z1=20


Where did I go wrong?
