DataPoint.SetValueY Method (Object[])

.NET Framework (current version)
 

Sets the Y-value(s) of a single data point.

Namespace:   System.Web.UI.DataVisualization.Charting
Assembly:  System.Web.DataVisualization (in System.Web.DataVisualization.dll)

public void SetValueY(
	params object[] yValue
)

Parameters

yValue
Type: System.Object[]

The Y-value(s) of a DataPoint object in the collection. Formatted as one or more values separated by commas.

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.

System_CAPS_importantImportant

The YValuesPerPoint property determines the maximum number of Y-values that all data points in a Series can have. If you specify more than the allowable number of Y-values, an exception will be raised.
