DataPointCollection::AddXY Method (Object, array<Object>)
Adds a DataPoint object to the end of the collection, with the specified X-value and Y-value(s).
Assembly: System.Web.DataVisualization (in System.Web.DataVisualization.dll)
Parameters
- xValue
- Type: System::Object
The X value of the data point.
- yValue
- Type: array<System::Object>
One or more comma-separated values that represent the Y-value(s) of the data point.
Return Value
Type: System::Int32An integer value that represents the 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 YValueType property of the DataPointCollection object that this data belongs to; if too many Y-values are specified, an exception will be thrown.
In order for DateTime formatting to have an effect, a value must be a DateTime object.
If your data points do not need an X-value—that is, if you are creating non-scatter plots—use the AddY method instead
