How to display a trendline, but hide the source data points/line

[paultechguy]

I have a busy chart with several data series and a trendline(s).  For a cleaner feel, I'd like to show a trendline for each individual series, but only display the data series for one of the trendlines.

Is there a way to hide the data series for a trendline, while still displaying the trendline?  I don't want to just change the color of the data series since hover would still work and be confusing on the data series.

Thanks.
