That's called linear regression analysis, or "least squares". You'll need

to do the math yourself - the formula calculates the slope and Y-intercept

of the best fit line. Using that, you'll need to manually add another

series (as a Line), with one X-Y point for each X position.

It's not rocket science...but, it's close.

Alternatively, I think there's a plug-in for ChartFX that supports that

requirement without your having to do the calculations yourself.
