Each graphic on the chart represents a ChartSeries object. It holds data, which is used for calculating the coordinates of the graphics as well various style and appearance properties. All ChartSeries for a chart are kept in the Series property.
Each ChartSeries has a Title property, which shows as a label in the ChartLegend should you use one.
The ChartSeries defines the Fills and Strokes used for painting the chart graphics that corresponds to this series. It also holds properties for labels drawn at the series - LabelFontFamily, LabelFontSize etc.
Line and Bar charts can contain unlimited number of LineSeries, BarSeries and CandlestickSeries objects. Pie and doughnut charts have just one, which is an instance of PieSeries. The order in which the series are added may influence the appearance of the chart.
Radar and polar charts use the RadarSeries object. They is no limit to the number of series you can add. Each series defines properties for the data of the chart, the labels and the scatter for the graphic, if scatters will be drawn.
Pie and doughnut charts use the PieSeries class. They can have only one PieSeries.
3D surface charts use SurfaceSeries. This class, as well all 3D series class derive from AxesSeries3D.
3D bar charts and 3D pie charts use the same ChartSeries objects as their 2D counterparts - BarSeries and PieSeries. That's because the location of the series in 3D bar and pie charts along the Z-axis is done automatically by the control depending on the type of the chart and its settings.
