What you probably want to use is the 'select' event, not 'regionClick'. When the select event fires, you call the #getSelection method of the chart, which returns and object with row and/or column information so you can reference the DataTable to find out what the user clicked on. You can then emulate a clicked link if you so desire (by setting window.location to whatever your desired destination is). You would use the same method for both BarCharts and GeoMaps.
As an aside, the Flashed-based GeoMaps have been replaced with the SVG-based GeoCharts (which have less compatibility issues). They don't * quite* support the same feature set, but almost anything you can do in the GeoMaps, you can do in the GeoCharts. I would recommend switching if there isn't anything you specifically need from the GeoMaps that the GeoCharts don't have. -- You received this message because you are subscribed to the Google Groups "Google Visualization API" group.
