I have several lines, which will be graphed prior year (12 months) or current
year to date (1 to 12 months).

On the far right side of the graph, I need to have the lines (at month 12)
intersect with a seperate visual showing multiple levels of the goal (like a
stacked column chart). I can't use horizontal goal lines across the chart-
they need to just be at the end.

When I set it up as a mixed-type chart, with the goal information in Dec
(stacked columns), the actual monthly lines travel into the goal area and
terminate in the center of that stacked column; what I'd really like is for
them to hit the "wall" at the 12 month data point, with the different levels
of goals will be just to the right of that wall.

Or, there may be better ways to do this that I haven't even thought of- I'm
open to options.

Any ideas, including any pointers for implementation?

Thank you!
Keith
