Look at UIRotationGestureRecognizer. - When the user moves the fingers opposite each other in a circular motion, the underlying view should rotate in a corresponding direction and speed.

There is a CPTGraphHostingView in core-plot SDK which contains all your plots. Attach that gesture recognizer to this view and see result.

See `UIPanGestureRecognizer` in this case – beryllium Nov 16 '11 at 10:45

Just check what direction was dragging. Something like this: if endPoint.x-startPoint.x>10 and endPoint.y-startPoint.y<10 then rotate it to left/right. There is no existing solution with gesture recognizers for get it, try yourself. – beryllium Nov 16 '11 at 10:52
