I have a resizable window, and a graph which consists of 11 lines of different values ranging from 0 to 1000. What is the math I would use to compute this?
I want to have the data ranging from 0 to 1000 be so that it equals 0-1000 pixels on screen. But if I resize my window to say 640 / 480, the graph will adjust only will be less detailed.
This is a simple proportion: if 640 pixels bar represents value of 1000, value of Y will represent 640 * Y / 1000 pixels bar.
