Area series views are intended to show filled areas on a diagram. In these series, values are represented by heights of peaks and hollows in each data point. Values can be used either separately (simple areas) or in an aggregated manner (stacked and full-stacked areas). To see the entire list of available area views or to switch your current view to another, please use the View Type combo-box on the top of this demo.
Also you can show or hide series labels by toggling the Show Labels checkbox in this demo's options.
