// Basic requirements for creating a waterfall chart:
//   1) Create a WaterfallChart instance and a data source 
//   2) Create a data model and attach the data source to it
//   3) Assign the Category variable role, and optionally the
//      Response variable role, to appropriate variable(s)
//   4) Assign the data model to the WaterfallChart
// To set a title or footnote, get the appropriate WaterfallChart
// title or footnote, and then set the returned object's text.

   // 3) Assign the Category variable role, and optionally the
   // Response variable role, to appropriate variable(s).
   // This sample sorts category values in descending order, and
   // it applies the NLMNLUSD format to the response variable so
   // that Transaction amounts in the output are displayed in an
   // internationalized representation of US dollars.
     
      dataModel.setCategoryVariable(

      dataModel.setResponseVariable(

  // 4) Assign the data model to the WaterfallChart
     waterfallChart.setDataModel(dataModel);

  // Set a graph title
     waterfallChart.getTitle1().setText("BIP Waterfall Chart");

  // 5) Set HTTP-specific response and request functionality
     waterfallChart.setResponse(response);
     waterfallChart.setRequest(request);

  // Set a graph size and write the chart to the display
     waterfallChart.setWidth(600);
     waterfallChart.setHeight(450);
     waterfallChart.write(out);
