That works perfectly. Now I also understand how letters and spaces sort. Duh. :)

Cheers,

Can you add a prefix to the converted-to-string by-variable that allows for
its sorting properly?  Perhaps something like:

clear *
set more off
input float byvar byte count
1.1 20
2.3 20
4.6 20
10.2 20
end
expand count
drop count
generate float x = runiform()
generate float y = runiform()
tostring byvar, replace format("%3.1f") force
replace byvar = " " + byvar if length(byvar) < 4
graph twoway scatter y x, by(byvar)
exit

I should say also that graph_by doesn't respect the variable format command,
although I think it should.


I have a variable that is numeric, like:

1.1
2.3
4.6

but about 20 levels to the variable. I want a to use graph_by where the by variable is the above, but I don't want the labels to show the float values. I could _string_ the numeric variable and graph_by that, but then
the order is not numeric on the graph.

How do I rapidly change a float numeric variable to a labeled numeric variable such that my graph_by is labeled more neatly, and in numeric
order?
