Hello,

Using Excel 2007 and W 10 on a PC.

Have a very simple graph.
Just Blood p reading vs. date.
Shows up fine.

But no matter what I try or do, I can't get it
to generate a Trendline.

Have selected the curve, and then tried from both the right-click, and
also the pull-down tab for.

Nothing seems to work.

Probably something "major" I am not doing, or something the program just
doesn't "like".

Any thoughts on what I might be missing ?

Thanks,
Bob
