Example
This example creates a chart control.
XYLineSeries series0 = new XYLineSeries();
series0.SeriesName = "Series 0";
series0.XValues.AddRange(new double[] { 1.0, 2.0, 4.0, 8.0 });
series0.YValues.AddRange(new double[] { 2.0, 4.0, 3.0, 5.0 });

XYLineSeries series1 = new XYLineSeries();
series1.SeriesName = "Series 1";
series1.XValues.AddRange(new double[] { 1.0, 3.0, 5.0, 7.0 });
series1.YValues.AddRange(new double[] { 1.0, 2.0, 4.0, 8.0 });

XYPlotArea plotArea = new XYPlotArea();

plotArea.Size = new SizeF(0.6f, 0.6f);
plotArea.Series.Add(series0);
plotArea.Series.Add(series1);

ChartModel model = new ChartModel();
model.PlotAreas.Add(plotArea);

plotArea.Size = New System.Drawing.SizeF(0.6F, 0.6F)
plotArea.Series.Add(series0)
plotArea.Series.Add(series1)
