Ratio

[The Little Guy]

I am trying to do a ratio, but can figure this out..

 

I am using flash to make a graph using data from a xml file.

 

val = the value from the xml file

20 = the amount of space that should be below the bottom

var ratio = 100 / stage.stageHeight;
var yp = (stage.stageHeight - (ratio * val)) - 20;

var ratio =  stage.stageHeight/100;
var yp = (stage.stageHeight - (ratio * val)) - 20;

 

Or I'm nuts.

This is exactly what I want:

 

var yp = -((val/max) * (stage.stageHeight - 30)) + stage.stageHeight - 20;

Isn't it amazing how much you actually use high school algebra when programming?
