I misrepresented the problem.

I should have said the graph looked something like:

 |    .         .
L|  .   .....  . .
O| .          .   ....
D|   ===        ==
  --------------------
   chromosomal position

where there is a line series (periods) representing lod score vs 
chromosomal position for a series a statistical test spanning the 
chromosome. Peaks in the lod score indicate position of a gene. 
Confidence in position is designated with equal signs (a 2 lod interval 
surrounding a peak). It's not hard to use three line commands in a 
graph tw, to generate the plot,

graph tw (line lod position) (line baseline gene1) (line baseline gene2)

But each plot takes up one serset (3 for the above command). I was 
wondering how to collapse the two plots (line baseline gene1) (line 
baseline gene2) into  (one). Doesn't seem possible, because graph tw 
(y1 y2 x) is not applicable here. Am I missing something easy?
