LabelFormatString to display other values other than x/y coordinates

I'm plotting points on WPF OxyPlot based on a defined set of point indexes.
For example, I have a file containing two sections:

Section 1 (x, y, width, temperature)
0.00000 8008.00000 303.89111
2.07055 8007.72754 286.60547
4.00000 8006.92822 274.70264
etc


Section 2 (vertexes)
1, 44, 45, 2
2, 45, 46, 3
3, 46, 47, 4
etc

Section 2 tells me in what order to plot the x/y coordinates from Section 1, so the first line in Section 2 says to plot points in line 1, then points in line 44, then points in line 45, then points in line 2 (of Section 1), etc.

I need to use LabelFormatString to display the vertex values, ie 1, 44, 45, 2, etc rather than the x/y coordinates.

Is this possible and how?

Is it for the tracker? If it's so you can use "Tag" property of LineSeries and bind it in XAML. See Tracker examples.

Good luck

Thanks for the reply.
Actually, it's NOT for the Tracker. I need to show the Index number for each vertex, AND, hopefully bind it's visibility in XAML to allow user to show/hide it.
If that's not possible, I could resort to the Tracker.

Then why you just do something like this:

for(int i=0; i<s2.Points.Count(); i++)
{
s1.Points.Add(new DataPoint(myList1X[i],myListY[i] );
s1.LabelFormatString = (s2.Points[i].X, s2.Points[i].Y)
}

Please note that I haven't tested this (you would probable need ToString() that).
For disabling that you could put a condition before LabelFormatString and redraw the LineSeries whenever the user clicks on that particular CheckBox. Good luck
