Thanks Akhilesh!!! I dont want two maps on view with both years. There should be one map. User should select if he wants to see month wise, quarter wise or year wise comparison.Now if the user selects month and selects Feb, which would be passed through parameters. the map should show the percent increase in profit from Jan to Feb. Hope you get my point here.
