This is a very common need and there are several user-written solutions
for it. Ulrich Kohler mentioned my -egen- function -axis()- from
-egenmore- (although then changed his mind) and Roger Newson mentioned
his -sencode-. 

A command that is I think exactly what you seek is -labmask-.

        outlines techniques for producing table-like graphs

reveals that the wonderful UCLA site contains two documents mentioning
-labmask- and also that since those documents were written I have
written up -labmask-'s application to graphs in the Stata Journal.
Regardless of whether you subscribe to the Journal you should install
-labmask- together with -seqvar- from the Stata Journal site. 

The code is also in the SSC package -labutil-, but installing from the
SJ site is better.

I have a question. My dataset is like this.

Matchscore   order             ymonth
200                 1                 1990m1
280                 2                 1990m1
290                 3                 1995m7
300                 4                 2000m3
251                 5                 2000m4

This is just a small part of the dataset, but it kind of gives the
message that ymonths are not evenly spaced and can be repeated ( this
is the reason I would not graph this by ymonth). So I want to graph
this by order but I want the corresponding values of ymonth displayed.

I want to do  something like : -
twoway ( line matchscore order )  , xlabel ( using ymonth in place of
order for the xlabel )

There is a clumsy way of pulling out the order values and ymonth
values and making a numlist but I was hoping there is something better
than this because I have to automate this process.
