DataPoint::SetValueY Method
Sets the Y-value(s) of a single data point.
Assembly: System.Web.DataVisualization (in System.Web.DataVisualization.dll)
The SetValueY property is used to set the Y-value(s) of a data point at run time.
Only one Y-value per point is required for all chart types except for 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.
This property returns an array of double values when used to retrieve multiple Y-values.
