Problem

ExcelWriter supports creating custom charts, including charts that contain several different chart types. For example, a chart wtih two area series and one line series.

Solution

This code snippet creates a chart with two area series and one line series:

Chart chart = ws.Charts.CreateChart(ChartType.Area.StandardArea,ws.CreateAnchor(5, 0, 0, 0));
chart.SeriesCollection.CreateSeries("A1:A3");
chart.SeriesCollection.CreateSeries("B1:B3", ChartType.Area.StandardArea, AxisType.Primary);
chart.SeriesCollection.CreateSeries("C1:C3", ChartType.Line.StandardLine, AxisType.Primary);
