Example

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.

  C#

  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" });
          }
      }  
  }
