Well... that could work. Problem is in the actual graphs I'm making, there
are to be >30 lines per graph (as many as 60 in some cases). Any way I could
use the lines command without having to write out 60 lines of code per
figure? That's why I like ablines; you just have to specify a single value
and it will put a horizontal line at that number.

Thanks,
Ryan
