Dynamic Polygon circle Radius calculations based on Perticular fact/value

var currentVal:Number = Number(ObjectUtil.toString(arryAll[i][‘revenue’]).toString());
var revenueDifference:Number = maxVal – minVal;
var radiusDifference:Number = radiusMax – radiusMin ;
var factorValue:Number = radiusDifference/revenueDifference;
var calculatedResult:Number = radiusMin +( currentVal – minVal) * factorValue;

Finaly pass the ‘calculatedResult’ into the Radius of the Polygon
