Pareto Charts

In This Topic

A pareto chart contains both bars and a line graph. Individual values are represented in descending order by bars and the cumulative total is represented by the line. The pareto chart is used to highlight the most important items in a set of values.

For information about creating charts in the Spread Designer or the Chart Designer, refer to Using the Spread Designer or Using the Chart Designer.

Using Code

Add data to the control.
Add a chart to the Spread control using the ParetoSeries class.

Example

The following example creates a pareto chart.

C#	Copy Code
FpSpread1.ActiveSheetView.RowCount = 30; FpSpread1.ActiveSheetView.ColumnCount = 10; FpSpread1.ActiveSheetView.Cells[0, 1].Text = "Test Score"; FpSpread1.ActiveSheetView.SetClipValue(1, 0, 13, 1, "Class1\r\nClass1\r\nClass2r\nClass2\r\nClass3\r\nClass2\r\nClass3\r\nClass2\r\nClass3\r\nClass2\r\nClass2\r\nClass3"); FpSpread1.ActiveSheetView.SetClipValue(1, 1, 13, 1, "20\r\n35\r\n40\r\n55\r\n80\r\n60\r\n61\r\n85\r\n60\r\n60\r\n64\r\n75"); FpSpread1.ActiveSheetView.AddChart(new FarPoint.Web.Spread.Model.CellRange(0, 0, 13, 2), typeof(FarPoint.Web.Chart.ParetoSeries), 400, 300, 150, 0);
