st: multiple colors in twoway plots

[Jeph Herrin <junk@spandrel.net>]

Is there a way to assign a different color or
pattern (-linestyle-) to different x-values in
a -twoway- graph?

I'm using -twoway rcap- with the -by- option,
so I have a lot of stacked figures, and would
like to use line attributes to distinguish them.

thanks,
Jeph
