run this code & note how the totals are different:

		private void InitializeChart()
		{
			FastLine funcSeries = new FastLine(tChart1.Chart);
			funcSeries.Marks.Visible = true;
			Steema.TeeChart.Functions.Add chartTotalFunction = new Steema.TeeChart.Functions.Add();
			chartTotalFunction.Period = 5; 
			chartTotalFunction.PeriodAlign = Steema.TeeChart.Functions.PeriodAligns.Last;
			chartTotalFunction.PeriodStyle = Steema.TeeChart.Functions.PeriodStyles.NumPoints;
			funcSeries.Function = chartTotalFunction;


			Line series = new Line(tChart1.Chart);
			for (int i = 0; i < 20; i++)
			{
				series.Add(i, i);
			}

			funcSeries.Marks.Visible = true;
			series.Marks.Visible = true;
			funcSeries.DataSource = series;

			double tot1 = funcSeries.YValues.Total;
			double tot2 = series.YValues.Total;
		}
