There are various possible solutions.

1. -replace- the variable with itself multiplied by 100000.

2. -clonevar- the variable ditto.

In either case, you will need to change the variable label if you are
like me and put units of measurement in variable labels.

3. Stata will accept  e.g. -ylabel(42 "foobar")- and so -ylabel(1
"100,000")- etc.

4. A helper command for #3 is -mylabels- (SSC).

The principles here apply to nonlinear re-scales too. See
