Hi Mark -

Brian Murphy discusses the bezier curves Excel uses to draw the smoothed curve
connecting the points. Look for a link on his main page to his Excel stuff:

In an XY Scatter Chart, where the selected chart
is, "Scatter with data points connected by smoothed Lines
without markers.", is there a way to obtain the function
of the line?

Perhaps not... since an XY scatter wouldn't necessarily
need to be a function, but this one is. (the trendlines
don't fit well, though.(

Thanks.
Mark
