Trendline of multiple series

Is there anyway I can create a trendline that incorporates thre
different sets of data on the same graph? :

Hi,

You would need to add an extra data series that incorporated all 3 sets
of data. You could then add a trendline to this single data series.

The additional data series can be formatted, no pattern or border, so it
does not appear on the chart.

Cheers

Or calculate the trendline in a worksheet and plot the trendline as a
separate series.
