Hi,
In the rotationEnd event of a chart, the arguments given are 'startingAngle' and 'changeInAngle'. As the former parameter actually gives the angle at completion, In the context of rotationEnd, a better name would be 'endingAngle'.
I was under the brief misapprehension that 'startingAngle' here meant the original angle before the rotation. It doesn't make sense to call it 'startingAngle' here.
Indeed, the function to set the angle of a chart is also called 'startingAngle()' - why not just 'angle()'?
