Changing gnuplot range without affecting the origin

Question

I would like to plot the graph a function (say y=x) in the range [-10:10] for both axes. If I write

gnuplot> set xrange [-10:10]
unset tics
set border 3
gnuplot> plot x

I get a graph in which the axes are centered on -10, -10, but I would like to have the axis centered in the origin 0, 0. How can I do this? I've tried by setting

set origin 0, 0

but it doesn't work. Thank you.

set origin is for placing the origin of a subplot on the screen. i.e. You can use it to shift the placement of the entire plot on the screen. — mgilson

You need to use

 set zeroaxis

You can change the line type and line width by adding linetype n and/or linewidth n

Nice. +1 from me. (you can also change the linestyle using ls n).

Works fine for me too. Setting zeroaxis, border 0, tics axis. Thanks
