Hi,
I have a chart with dates in the horizontal and number values in the
vertical axis. Added a Polynomial trendline with order 2.
Now I will need to extract the data points with both horizontal and
vertical
values that are touching the treandline.

Any help, how would this be possible. Thanks in advance.
