Graphs, trendlines etc

Hi All,

With reference to the image below.....


-- removed inline image ---

I would like to set a "flag" cell that says "out of limits" if 'Plot Point A' is outside the "In Limits (Green) Area" of the chart which is enclosed by the six trend lines connecting the corner plot points together.

Any ideas anyone?

Thanks for ANY help
