Property Value

Type: System::Int32
An integer value that represents the index of a data point returned by a hit test. The default value is negative one (-1).

If a data point is at the location that is checked by a hit test, the PointIndex property will return the zero-based index of that data point, otherwise it will return a negative one (-1).

All data points are stored in a DataPointCollection, which is exposed as the Points collection property of a Series object; the index of the DataPointCollection is zero-based.

Use the Series property to determine the series to which the data point belongs.
