You might like to use the -regaxis- package, which you can download from 
SSC within Stata using the -ssc- command. If you do this, and type

regaxis x, cycle(2) ltick(xlabs)
twoway scatter y x, xlabel(`xlabs')

then -regaxis- will store in the macro xlabs a sequence of x-axis labels, 
spanning the range of x and separated by a cycle length of 2, and -twoway 
scatter- will use `xlabs' as the X-axis labels.

The -regaxis- package is a general solution to creating regular axis label 
sequences and ranges, which can either be linear (using the -regaxis- 
program) or logarithmic (using the -logaxis- program). You can find more 
about it by typing

findit regaxis

and reading the on-line help.

I hope this helps.
