To set the axis lengths (in centimetres), use commands like ``set x size 5`' and ``set y size 7`'. Some people like the ratio of axes to be in the so-called golden ratio ``(root(5)-1)/2`'; to get that, you could do this:
    set x size 15
    set y size {rpn ..xsize.. 5 0.5 power 1 - 2 / *}
For maps, you'll want the plot scaled so that shapes retain their aspect ratio. To do this, do ``set x size .cm.`' and then do ``resize y for maps`' (or vice versa).
