So I effectively have a image I'd like to zoom horizontally but also be able to respect the location of the pinch. So if you pinched on the left, It'd zoom into the left. Ideally, the points where you pinch would stay with your fingers.
My case is a little more specific, I'm plotting data on a graph, so I instead will be manipulating an array of data and taking a subset. However, I'm sure the math is similar. (BUT, I can't just use an Affinetransform as most examples I've found does)
Any ideas?
The default pinch gesture handler scales the graph around the point of the gesture. Use a plot space delegate to limit the scaling to only one axis.
