Not to scale axis. Custom axis.

[Emmanuel Garcia]

Hi,

I was wondering if there is a way to have special scale axis in a graph to make a sort of zoom. So for example, in a graph with a yrange from 1 to 10, make it so as the graph's height between 1 and 2 is the same as between 2 and 10.

Thanks

A negative reciprocal scale comes close and is not extraordinarily esoteric.

clear
set obs 10
gen y = 42
gen x = _n
gen recx = -1/x
mylabels 1/5 7 10, myscale(-1/@) local(labels)
scatter y recx , xla(`labels') ms(Dh) xtitle(x) note(negative reciprocal scale)

Logarithmic scales are easier to explain, however!

Thank you so much Dr. Cox, this is an incredibly useful solution. I also love logarithm scales, but some medical journal editors do not share our common love!

Ah, Chris, you mustn't explain in-jokes.
