Remarks

This method adds one data point to the DataPointCollection object, always adding it 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 Series object this data belongs to, and 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 your data points to use an X-value call the AddXY method instead.

For DateTime formatting to have an effect a value must be a DateTime object.

Refer to the following for a complete listing of valid .NET types that can be used for the object type parameters:
