Scott Merryman gave an excellent answer:
just define text for your labels directly.
Another partial answer is to use
a user-written program -mylabels-
from SSC.
This is best explained through your example.
I want my labels to be 0(10)100, but
my underlying scale is in fact 1/100
of those numbers. This program call works
out the -?label()- argument and stores it a local macro:
. mylabels 0(10)100 , myscale(@/100) local(labels)
0 "0" .1 "10" .2 "20" .3 "30" .4 "40" .5 "50" .6 "60" .7 "70" .8 "80" .9
"90" 1 "100"
The @ is a placeholder for the numbers concerned.
. graph box myvar, yla(`labels')
The gains and losses here should be clear,
especially for automating any procedure.
-mylabels- does not give scope for adding extra text fore or aft,
the % sign in this case. I suppose that was
driven by the programmer's own preferences.
Naturally in this case the calculation could be
done mentally, making direct specification of label
text competitive. -mylabels- scores for more exotic
scales like square roots, cube roots or logits.
