Interface IChartSeriesIndexedModel

Interface that is to be implemented if you want the ChartControl to be able to display your indexed data (X value is not needed). The ChartControl is totally agnostic about the data it displays. Even the default series store is an implementation of IChartSeriesModel. When you implement this interface, you can set it as the data underlying any ChartSeries object using the SeriesIndexedModelImpl. When you use this model for a series, you have to set ChartControl's Indexed property to be True.
