Remarks

This method adds one data point to the DataPointCollection object, inserting it into the specified location.

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.

If your data points do not need an X-value (e.g. if you are creating non-scatter plots) then use the InsertY 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:

String

DateTime

Double

Decimal

Single

Int32

UInt32

Int64

UInt64
