Get Max value from graphic.

[Dan Ebberts]

Not directly from the graph editor, but you can analyze whatever property is driving the graph, with something like this:

prop = thisComp.layer("White Solid 1").effect("Slider Control")("Slider");
for (i = 0; i <= thisComp.duration; i += thisComp.frameDuration){
  max = (i == 0) ? prop.valueAtTime(i) : Math.max (max, prop.valueAtTime(i));
}
max

but there will be a tradeoff between resolution and processing time. The example above checks the value every frame, but you could change it to check more often if you need finer resolution.
