Client-side GChart 2.4 was just released today, It supports click events, so that might help you. Unfortunately, there are still no client to model coordinate conversion functions. Please consider adding a request for this feature to the GChart issue tracker. In the meantime, looking at the setClientX, setClientY, xToPixel, yToPixel internal methods in GChart.java might help you to implement such conversion functions on your own (I had considered adding a clientToModel method within the Axis class for 2.4, which is where I think this fits into the current API).
Appreciate hearing that you found the product helpful. John C.
