In Adobe's dashboard sample app, http://www.adobe.com/devnet/flex/samples/dashboard/ it assigns a charting component's dataProvider to an ArrayCollection's source (e.g. revenueData="{slicedRegionData.source}") In the regionChange() function it sets the array regionData and assigns it to slicedRegionData.source My question is, the delivered code slicedRegionData.source = regionData.slice(slider.values[0], slider.values[1] + 1); Alert.show(ObjectUtil.toString(slicedRegionData.source)); and slicedRegionData.source = regionData; Alert.show(ObjectUtil.toString(slicedRegionData.source)); Without the .slice, output the exact same data, but the region detail does not auto update without using the .slice code. WHY??? Thanks for any insight on this. Robert
