Added missing base.UpdateData() call in DataPointSeries
Added missing base.UpdateData() call in DataPointSeries

Make sure base.UpdateData() is called in DataPointSeries, otherwise XYAxisSeries.WindowStartIndex is not reset to zero in XYAxisSeries.UpdateData() after a data change (because the base method is never called). A (previous) initial guess from WindowStartIndex outside the end of the new array of data points will always produce a (wrong) start index at the end of the array when calling XYAxisSeries.FindWindowStartIndex (for example from LineSeries.RenderPoints).
