CGFloat from a float?

How do you cast or create a CGFloat from a float?

I get a bad receiver type float * error. 

CGFloat point = [graphValues objectAtIndex:0];

That's because the array is not an NSArray but a float array.

CGFloat point = graphValues[0];

If you want to know how CGFloat is declared, have a look in the header (it should be a double).

graphValues is probably not an NSArray, but a C-array of floats. If so, you want this:

CGFloat point = graphValues[0];

(The reason I think this is because it's telling you you're trying to call an Objective-C method on a float *.)
