Automatic legend creation for Range Maps(Thematic maps)

[sb82]

I have data for more than 100 world indicators(like Population, Birth rate etc) for different years.

Presently I use Google Geomaps to display them. http://code.google.com/apis/visualization/documentation/gallery/geomap.html

I am looking forward to use FusionMaps...and have a question regarding the legend.

In google geomap I send all the values to Google server and it calculates the legend and color range by itself...is it possible to achieve such automatic functionality...my data is dynamic..and so am not sure how will I achieve this. 

Thanks

Hello,

You can use JavaScript to do so. You fetch the values using JavaScript, build the XML and the use setDataXML method to update the map after a specific interval.
