Hi,
I am trying to understand the pinch zoom feature here. i had added the graph class with two touch handlers and swipe touch handler, with this i am able to detect two finger touch events. I had added 100 data points to create a graph and trying to zoom it. As i had zoomed it, it is observed that the graph is expanding in x-axis direction, but not on y-axis. Can anyone point out what's need to be done to achieve two-dimensional zoom.
