You can create a (trend)line between two known points - they have to
be on the chart. Future values on the line can be determined by the
slope of the line.
You will have to solve the problem of a line which is itself not
anchored, if it is event driven as you suggest. If you can work out a
way to have the end points fixed to a specific date, and not an
event, you should be able to do what you want.
MSTT has had a few articles on drawing lines which may be helpful.
Still the problem will be creating a line which isn't dynamic..
