Using GPU (GL?) for multi-platform stock charting software

Were trying to make a stock market charting software with Unity. It includes some gaming elements but the main module are the graphs/charts. The charts need to be fully interactive, our inspiration is IQ Option (uses WebGL).

Because the charts are made of many points and lines and should move interactively the CPU usage is quite high. Even when we optimize our code it's not the same as running on WebGL.

Is there anyway to improve our graph calculation performance using GL in Unity and still be multi-platform ?
