    Funnel Charts
    In This Topic

    A funnel chart shows values across multiple stages. The values typically decrease at each stage.

    Funnel charts are useful for sales and other types of data. For example, determining how many web site visits lead to product purchases.

    An example of funnel chart

    You can use the FunnelSeries class and the YPlotArea class to add a funnel chart.

    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

    1. Add data for the chart with the FunnelSeries class.
    2. Specify the plot area.
    3. Add the chart.

    Example

    This example creates a funnel chart.

    C#
    Copy Code
    FarPoint.Web.Chart.FunnelSeries funnel = new FarPoint.Web.Chart.FunnelSeries();
    funnel.Values.Add(200);
    funnel.Values.Add(180);
    funnel.Values.Add(50);
    funnel.Values.Add(30);
    funnel.Values.Add(8);
    funnel.CategoryNames.Add("Leads");
    funnel.CategoryNames.Add("Emails Sent");
    funnel.CategoryNames.Add("Replies");
    funnel.CategoryNames.Add("Quotes");
    funnel.CategoryNames.Add("Purchases");

    funnel.BarFills.AddRange(new FarPoint.Web.Chart.GradientFill[] { new FarPoint.Web.Chart.GradientFill(Color.LightGreen, Color.Yellow), new FarPoint.Web.Chart.GradientFill(Color.LightBlue, Color.Thistle), new FarPoint.Web.Chart.GradientFill(Color.LightGray, Color.LightPink), new FarPoint.Web.Chart.GradientFill(Color.Beige, Color.Orange), new FarPoint.Web.Chart.GradientFill(Color.LightSalmon, Color.RosyBrown) });
    funnel.BarBorders.AddRange(new FarPoint.Web.Chart.Line[] { new FarPoint.Web.Chart.SolidLine(Color.DarkOliveGreen), new FarPoint.Web.Chart.SolidLine(Color.DarkBlue), new FarPoint.Web.Chart.SolidLine(Color.Black), new FarPoint.Web.Chart.SolidLine(Color.DarkOrange), new FarPoint.Web.Chart.SolidLine(Color.Firebrick) });

    FarPoint.Web.Chart.YPlotArea plotArea = new FarPoint.Web.Chart.YPlotArea();
    plotArea.Location = new PointF(0.2f, 0.2f);
    plotArea.Size = new SizeF(0.6f, 0.6f);
    plotArea.XAxis.Reverse = true;
    plotArea.Vertical = false;
    plotArea.Series.Add(funnel);
    FarPoint.Web.Chart.ChartModel model = new FarPoint.Web.Chart.ChartModel();
    model.PlotAreas.Add(plotArea);
    FarPoint.Web.Spread.Chart.SpreadChart chart = new FarPoint.Web.Spread.Chart.SpreadChart();
    chart.Model = model;
    chart.Left = 0;
    chart.Top = 150;
    chart.Height = 600;
    chart.Width = 400;
    FpSpread1.ActiveSheetView.Charts.Add(chart);
