<%// ChangeBarWidth:%>

<%
// A graph's display properties (bar width, orientation, axis characteristics,
// and so on) are general properties that are defined in the graph's model.
// Thus, to change the width of bar elements,
//    1) Get the BarLineChart's graph model
//    2) Call setGrowBarWidthEnabled() to set the boolean to true
//    3) Call setBarWidth() to set a width for the bars
