Map charts support the highlighting of countries/states, not regions. In order to highlight North America, you would have to highlight all the countries in encompasses.
The first examples within the Supported Parameters section of the documentation shows how to add markers/labels: http://code.google.com/apis/chart/docs/gallery/new_map_charts.html#supported_params You would have to attach the label to a specific country within the region. Not what you wanted to hear, but I hope it helps - Cheers, Keith -- You received this message because you are subscribed to the Google Groups "Google Chart API" group.
