Hi there ,

I think this is a relatively simple problem but I am lost! Please can someone tell me how one would combine more than one series in a graph graphically?
Allow me to explain.. .

I have a single graph on excel with 4 different series (curves) each having a different slope. I want to be able to plot a single series representing all these curves. How would I do that? I am aware of the trendline feature but that only lets you plot a trendline for the same series. What happens to multiple serieses?


Thanks so much in advance
