Remarks
The DataPoint class stores properties associated with data as well as data point values. For example, a data point has a value, but it also has a color property, background image property, background gradient property, and so forth. For more information about data point properties, see the DataPointCustomProperties class overview topic.
Each data point consists of an X-value and one or more Y-values. The X-value can be zero, or you can set this explicitly.
Only one Y-value per point is required for all chart types except bubble, candlestick and stock charts. These chart types require more than one Y-value because one data point consists of multiple values. For example, to plot one stock chart column, four values are required: high, low, open and close values.
Data can be added at either design time or run time; you can also use data-binding at run time.
Constructors
