ProfileData Property

Use this property to return/set the x & y data point values for a specific Profile.

Syntax

[Visual Basic]
Property ProfileData(ProfileIndex As Integer) As Object

[C#]
object XYChartNETCtl.get_ProfileData(int ProfileIndex)
void XYChartNETCtl.set_ProfileData(int ProfileIndex, object Value)

[C++]
property System::Object ^ XYChartNet::XYChartNETCtl::ProfileData[int]

Parameters

ProfileIndex: The index of the profile to set/get the x & y data point values of. Valid values are 0..(NumProfiles - 1).

Remarks

ProfileData is a two-dimensional array (Number of Rows - 1, Number of Columns - 1) of double. The number of rows is Profile(idx).NumSamples, where idx is the profile index to set/get the x & y values for. The number of columns is 2, one to store the x-data and one to store the y-data.

Initially, all data values are 0. Two common methods to populate the ProfileData array are:

Set ProfileData equal to a two-dimensional array.
Read data from a CSV text file into a two-dimensional array, and then set ProfileData equal to the array.

Example 1: Set ProfileData equal to an array
