Drawing Trendlines in Subgraph 2

["John Lynch" <kiwi_trader@xxxxxxxxxxxx>]

I'm trying to construct Andrews Babson Lines on an indicator rather than on
price.  To do this I need to be able to draw trendlines in Subgraph 2 (or 3
...) instead of Subgraph 1.

I normally use the TL_New and TL_End functions to draw the trendlines but
can't figure out how to make TS write the result in a different subgraph.
Can someone please help me?
