// To set bar colors so that they represent a chart variable's values:
//    1) Call the data model's setStyleByVariable() to specify the
//       variable whose values will be represented by the colors
//    2) Call the graph model's setColorPaletteType() method to set
//       a three-color palette
//    3) Get the graph model's DataElementStyles to set start, end, and
//       neutral colors for the bars
