You might try something along these lines:
clear
set obs 16
gen B = _n
gen C = B^.5
gen A = B
line A B, xla(1 "1" 16 "16") || line A B, xaxis(2) xla(1 "1" 16 "256", axis(2))

and if you need to construct a set of labels to put in xla(.), you may
want -levelsof- and a loop using -foreach-.

```Hi, listers

I have three variables where variable A can be derived from each of the
two others (B & C). I now want to create a line-graph with the value of
variable A on the y-axis and the corresponding values of B and C on
xaxis 1 and 2 respectively.

In case this was as hard to understand as it was to explain, I'll
elaborate with an example:

clear
set obs 100
gen B = _n
gen C = B^.5
gen A = B
line A B

I want to include a second x-axis which shows the corresponding values
of C.

Can this be done somehow?

My dataset only contains 16 points, so suggestions for ugly hacks are
also welcome :)
