This example shows how to create a chart with a data series of the waterfall view.

  • Add a series to a chart.
  • Specify the series data members.
  • Use the WaterfallSeriesView object to configure the series view options.
  • Specify value options. If data source stores value differences, use the WaterfallRelativeValueOptions. Use the WaterfallAbsoluteValueOptions class if the data source stores absolute data values.

    private void Form1_Load(object sender, EventArgs e) {
        chartControl1.DataSource = LoadDataTableFromXml("../../Data/carbon.xml", "CarbonContribution");
        Series series = new Series("Carbon Balance", ViewType.Waterfall);
        series.SetDataMembers("Year", "Contribution");
        series.ArgumentScaleType = ScaleType.Qualitative;
        chartControl1.Series.Add(series);
        ((WaterfallSeriesLabel)series.Label).Position = WaterfallSeriesLabelPosition.OutsideEnd;
        series.LabelsVisibility = DevExpress.Utils.DefaultBoolean.True;
        WaterfallSeriesView view = series.View as WaterfallSeriesView;
        if (view != null) {
            view.RisingBarColor = Color.FromArgb(218, 88, 89);
            view.FallingBarColor = Color.FromArgb(146, 206, 181);
            view.SubtotalBarColor = Color.Gray;
            view.TotalBarColor = Color.DarkGray;
            view.StartBarColor = Color.LightGray;
            view.ConnectorColor = Color.Black;
            view.ConnectorStyle.Thickness = 1;
            WaterfallRelativeValueOptions valueOptions = view.ValueOptions as WaterfallRelativeValueOptions;
            if (valueOptions != null) {
                valueOptions.StartBarLabel = "1989";
                valueOptions.StartBarValue = 2766D;
                valueOptions.ShowTotal = true;
                valueOptions.TotalLabel = "2018";
                valueOptions.Subtotals.Add(new Subtotal { PointIndex = 16, Label= "February 16, 2005" });
            }
        }  
    }
