Every other month is either a set of
odd numbers or a set of even numbers,
depending on the start point.
For example,
levels month if mod(month,2) == 0, local(show)
picks up the even months, which will
be Jan Mar May Jul Sept Nov, given
Stata's origin 0 = Jan 1960.
So you can go
... xla(`show', ang(v) labsize(vsmall))
Every third month can be done with a similar
trick.
Even more direct is just to use a numlist
... xla(251(3)349, ang(v) labsize(small))
but that requires either working it out
by hand or something else previously.
It could in turn be automated.
Ulrich Kohler wrote an -egen- function
as a helper for the second problem.
