I'm evaluating using Google Charts/Visualization to display line graphs within an app on an iPad.
I'm able to get the sample charts to display in a UIWebView and it looks great. However, I am unable to get pan, pinch and zoom to work. The browser ends up zooming the entire content of the browser, i.e. Google Charts is not changing the graph. What capabilities are supported for a mobile, touch based browser experience? Ideally in the simple line graph example, it would be nice to support zooming by pinch and zoom gestures. The line graph example supports displaying discrete values when a mouse is hovered over a data value. Ideal equivalent behavior in a mobile, touch based browser would be to allow the user to touch with one finger and have the value associated with that position on the graph displayed, and to display updated values as the user moves their finger. Panning the graph would ideally require a subtly different gesture, either two finger, or maybe by default it pans unless you do a long press to start displaying values. But thats all conjecture. Does Google Chart support touch at all in a mobile browser? Specifically pinch and zoom and some form of panning.
