Hi Chris. Currently this is not yet implemented using the visualization API.
If you want you can implement some of these interactions yourself using html image map and two calls to the charts api. When adding the parameter &chof=json to the charts api you will get a json structure which represent the locations of most of the visual objects in the image. Hope this helps, Viz Kid On Thu, Jan 14, 2010 at 7:55 PM, Chris Lowe <[email protected]> wrote: > There's a nice example of a clickable annotation which has been added > to an image chart on the Google AppEngine status page, for example: > > > http://code.google.com/status/appengine/detail/datastore/2009/12/09#ae-trust-detail-datastore-get-latency > > The main graph appears to make two calls to the chart API - one to > render the image and another to fetch chart data points in a JSON > format.
