You should probably reproduce the problem with a dataset shipped with Stata.
Is the time variable numeric or string?

Betreff: Re: st: RE: Graphing time on the x axis
Maybe I was unclear in my description of the graph, but i dont think it is a
scale or label question. The problem is that given the coordinates (00:00,
2.3) (05:36,1.9) (07:20,3.1) (18:58,2.9) they are not graphed in that order;
Instead I have (07:20,3.1) (18:58,2.9) (00:00, 2.3) (05:36,1.9) ...
