I'm looking to setup a line graph as part of a combined chart I'm working on for a business model. I would like to have one line which is the total of two datasets and showing those two data sets differently (either by color or style of the line)

So to clarify, I would like to show $10 in Revenue A revenue type, $15 in Revenue B revenue type, but for the total to be the one line on the graph at $25. And if it's possible to show A in green and B in red, or A as a squiggly line and B as a solid, or something along those lines. Appreciative of any feedback.
