How to display on a graph.

You need to have the score from each screen in a uniquely named component, so that there are no naming conflicts. Then, on the score screen, you can have a graph where you sink in a number from each of the screens that you want to include.

Here is an example activity that does this: CYU 4-4 (Math 3): Function Composition and Paper Box • Activity Builder by Desmos

Let me know if you have any questions.
