DataPointCollection::AddY Method (array<Object>)
Adds a DataPoint object to the end of the collection, with the specified Y-value(s).
Assembly: System.Web.DataVisualization (in System.Web.DataVisualization.dll)
Parameters
- yValue
- Type: array<System::Object>
A comma-separated list of Y-value(s) of the DataPoint object added to the collection.
Return Value
Type: System::Int32An integer that represents the location in zero-based index where the item was inserted into the collection.
This method adds one DataPoint object to the DataPointCollection; the data point is always added to the end of the collection.
You must provide at least one (1) Y-value, otherwise an exception will be thrown. This method also checks the ChartType property of the DataPoint object this data belongs to; if too many Y-values are specified, an exception will be thrown.
The X-value will always be set to zero (0), resulting in non-scatter plots. If you want the data points to use an X-value, call one of the AddXY methods instead.
In order for DateTime formatting to have an effect, a value must be a DateTime object.
