Prime 2 Plots

I have been using MathCAD since 2.6 and currently using v15. Prime 2 looks like it has some good features and will use all the power of the new operating system. My concern is the ability to clearly document results. Plots have to have the X and Y axis labeled. Each line needs a label. v15 did this using legends. What is the best method to accomplish this with Prime 2?
