Here is the problem as it stands:

First some sample data:

02/05/07 88.9%
02/12/07 80.6%
02/19/07 85.8%
02/26/07 84.4%
03/05/07 93.0%
03/12/07 90.6%
03/19/07 96.3%
03/26/07 87.0%
04/02/07 90.4%
04/09/07 91.0%
04/16/07 84.7%
04/23/07 91.7%

What Needs to be found:
Based on the trend when will the utilization go above 95% based on a
linear growth trend.

Why:
I need to graph a bar indicating when that 95% mark is met (for
capacity planning.)

How did this come about:
Normally I throw on a trendline and manually move a marker. I would
rather, for the sake of accuracy have the indicator plotted.

Any suggestions? All I need back is the date this happens (I'll be
setting the bar to 100% manually as to make a wall)
