Method: XRelation for AssignmentChannel <Data>

Method: XRelation for AssignmentChannel <Data>

Specifies the x-channel for an xy-channel. The x-channel must be in the same channel group as the y-channels. You cannot convert waveform channels into xy-channels because waveform channels already contain the x-part.

Set oChannel = Object.XRelation()

The following example displays the associated x-channel for an xy-channel.

Dim oMyChn 
Set oMyChn = Data.Root.ChannelGroups(1).Channels(2)
Dim oMyXChn

If (oMyChn.IsKindOf(eDataChannelPair))Then
  Set oMyXChn = oMyChn.XRelation 
  Call MsgBox(oMyXChn.Name)
End If 

oMyChn = dd.Data.Root.ChannelGroups(1).Channels(2) 
if (oMyChn.IsKindOf(dd.eDataChannelPair)): 
    oMyXChn = oMyChn.XRelation() 
    print(oMyXChn.Name) 

The following example specifies the first channel of the first group as x-channel of the second channel of the first group:

Dim oMyChnX, oMyChnY
Set oMyChnX = Data.Root.ChannelGroups(1).Channels(1)
Set oMyChnY = Data.Root.ChannelGroups(1).Channels(2)
Set oMyChnY.XRelation = oMyChnX 

oMyChnX = dd.Data.Root.ChannelGroups(1).Channels(1) 
oMyChnY = dd.Data.Root.ChannelGroups(1).Channels(2) 
oMyChnY.XRelation = oMyChnX 

The following example deletes the xy-relationship of the second channel in the first group:

Dim oMyChnY
Set oMyChnY = Data.Root.ChannelGroups(1).Channels(2)
Set oMyChnY.XRelation = Nothing 

oMyChnY = dd.Data.Root.ChannelGroups(1).Channels(2) 
oMyChnY.XRelation = None
