arcgis 10.1, map display with circles and colors

Discussion created by vadivelan.gis on Jul 10, 2013

I have a point map service, the attributes are Expediture and income of US cities.

I would like to display the map with Circles and Colors, for eg., size of the circle represents the income and color of the circle represents the Expenditure. (based on the zoom level, it has to combine the cities, like clustering)

the examples are based on one field, how to do this with two columns, any example or stub code.,
