4.4: Axis Length

The axes are normally 10 centimetres long. 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).
