How to combine multiple trendlines in a single chart?

Question

I've been searching for the grammar for this theorem prover but I found none. There are only bits and pieces on their site. Does anyone by any chance in in possesion of the grammar for this thing or is able to tell me where I can look for it

Solution

This is more for one trendline but with multiple series, what I would do is:

• Make a series of all needed values per row added together.

• Then divide by how many there are (2, divide by 2, 3, divide by 3, etc.).

• Next, make a graph like usual with all needed series including the one you just made.

• Then create a trendline only for the one you just made.

You only need one series, because you can get multiple trendlines from a single series. Right click the series, choose Add Trendline, format the trendline. Again, right click the series, choose Add Trendline, format the trendline. Rinse and repeat.
