Adding a projected outcome (dotted line) to a Google Sheets chart.

Hello all,

I am looking for a way add a (dotted line) projected value into a Google Sheet chart. I am plotting two sets of numbers on a graph, but the final averages for January are incomplete, and therefore show a misleading result. The averages in columns B and C are pulled from collected data in columns P ->.

The projected value could be either calculated automatically, and based on the total number of reported values in time elapsed. Meaning that the value will continue to go up. The value equals the number of days past, up to a maximum of 50.

If automating the projection is too complicated, I will also accept inputting manual value. I can work out my own projection analysis later. Right now, I am more interested in knowing how to create a chart like my mockup; see sheet.

In the example: https://docs.google.com/spreadsheets/d/1Q2nN-MVD_iwJi2Se-PFWcNbMGb-EF6gQWQCruhnWW-Q/edit#gid=180731546

Thanks, but I am not looking for a trend line. That is easy to do with a simple checkbox. :)

I what to add a projection to each of the data sets.

I finally figured out how to do it. It was easier than I originally thought.

One problem, I don't want the Projection labels to appear.

Is there anyway to omit them?
This is the best money I have ever spent. I cannot not tell you how many times these folks have saved my bacon. I learn so much from the contributors.
