Use this property along with the Column and Row properties to return/set any data point value for a specific Profile.

Syntax

[Visual Basic]
Property Data() As Double

[C#]
double XYChartNETCtl.Data

[C++]
property double XYChartNet::XYChartNETCtl::Data

Remarks

Initially, all data values are 0.

An error is generated when reading/writing the Data value if the Row value is not valid for the specified profile.

Example 1
