asrol,
If you look at the Plot Styles example in the folder I mentioned in the previous post there is a section of code there that you might want to refer to in order to recreate your data.
'=============================================================================
' Plot Curve Button Handler
'=============================================================================
Private Sub PlotCurve_Click()
    ' Create curve data
    Dim x(40)
    Dim y(40)
    Dim z(40)
    For i = 0 To 40
        x(i) = Sin(i / 3#)
        y(i) = Cos(i / 3#)
        z(i) = i
    Next i
In this example they create 3 arrays to represent the three dimensions of the array. For your case if you were to plug your data into two of the array (axes) that would give you the data for the channels, then you can simply input a constant for the third array it would produce a single line of your data as shown in your example GIF.  You can then repeat this process for each set of data, with a new constant value for that third axis, and it should manually create a graph that will look something like you desire.
