On behalf of wimps,
I am not sure about the terminology here.

More to the point, why not do it this way

graph tw scatter y1 y2 ... x if ...

Nick

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?
