// ColorBars:

    // 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
