ChSeriesCollection Collection Object
Multiple objects
A collection of all the ChSeries objects on a chart. A chart can contain up to 256 series.
Using the ChSeriesCollection Collection Object
The ChChart object’s SeriesCollection property returns a ChSeriesCollection collection.
Use the Add method to create a new series and add it to the chart.
Use SeriesCollection(index), where index is the series index number or name, to return a single ChSeries object. The following example sets the color of the interior for the first series in the first chart of ChartSpace1.
ChartSpace1.Charts(0).SeriesCollection(1).Interior.Color = "Red"
