My main focus is to draw charts. I am trying to place lines and other elements on a Canvas. The Canvas has its size determined by the window. I do not want to set any value that represents any coordinate of the window. I only want to set values that relate to the real world.
For example, the scale of the Canvas is X: 1 to 25, Y: 3.2 to 9.4
I am placing lines on the Canvas that would draw a line chart with points going from 1 to 25. How do I do this?
