Removing a single point from an OxyPlot Series

My question is simple. If you can add a point using OxySeries.Points.Add, is it possible to remove a single point from the series?

Yes, use the Points.RemoveAt method.
Remember to invalidate/redraw the plot afterwards (the model is not listening to changes in the Points collection).

Thanks, would you mind providing me with an example of the syntax. Is Points.RemoveAt(0) mean that it would remove the last point of the series?

No, index 0 is the first point, see http://msdn.microsoft.com/en-us/library/5cw9x18z.aspx

Thanks for the fast reply. So I've created a line series called hrseries and a plotmodel called hrtmp. When I call HR=hrtmp, it triggers the RaisePropertyChanged which I confirmed works correctly. Currently I'm clearing the lineseries and adding all the points to the lineseries every time I add a new point, which is slow. So I changed the code to remove one point at index 0 when its longer than 1000 points. Now my graph is empty. Is the code correct?

if (hrseries.Points.Count > 1000)
{
     hrseries.Points.RemoveAt(0);
}
hrseries.Points.Add(new DataPoint(xval, yval));
hrtmp.RefreshPlot(true);
HR = hrtmp;

Actually I found my mistake. Forgot to add:

hrtmp.Series.Add(hrseries);
