if I have a value of x= 10,000 y = 211.2 and an envelope
of 9500, 200: 13000, 211: 14000,214: 9500,214 can i use
NS range to check if the original coordinates are inside the
bounds of that rectangle...
if not any ideas how i might do that...
NSPointInRect(...) or CGRectContainsPoint(...)
The way I usually do graph plotting is to normalise (usually the
dependent variables) to the
height of the plot rectangle. Presumably you don't want plot
points to disappear simply
because they're larger than the size of the rectangle . . .
