MIT App Inventor Help

Hello People of the community of MIT App Inventor.
I am looking for help.
I need to make an app to view Triangular Diagrams. (plot inside the triangle).
I have seen x/y diagrams, bars and circular, but not Triangular (the center is the 100% and the vertices are 0, in the middle are a part of 3 portions of a 100%
(example a=10 b=20 and c=70... will have more of C, and less of a and b).
Any idea how to search where i can find an extension or how to code it?
I am not programmer and i need help to make an app for Geology (i use the diagrams for make proportions of a chemical in minerals).
It's for educational purpose.

Is for do graphics like this.
