Re: st: Formula/algorithm Stata uses to calculate default axis ranges and tick marks?

[Maarten Buis <maartenlbuis@gmail.com>]

The program that creates those tick values (-_natscale-) is build in
so we cannot take a look at it. However if you just want a program to
create "nice" tick values you can use -_natscale-.

Hope this helps,
Maarten
