The Visualization API does not have good support for touch events. From your description, I suspect that the browser is treating the tap as a mouseover, not a click. You can map touch events to mouse events, which I have heard works for fixing these kinds of problems. There is a good post on StackOverflow with an example: http://stackoverflow.com/a/1781750/613559
