I managed to use
 
allowDrag
	as per example 
	 
 
"dataset": [{
                "seriesname": "Android Devices",
                "data": [{
                    "value": "73",
                    "alpha": "100",
                    "allowDrag": "1"
                }, {
                    "value": "80",
                    "alpha": "100",
                    "allowDrag": "1"
                }]
	My question is, how can I disable this dynamically? Is there a way to apply "allowDrag" on whole chart rather than dataSet? My intension is to set allowDrag depending on other states in application.
