// SetInsideLabel:

// A graph's display properties (labels, bar width, orientation, and
// so on) are general properties that are defined in the graph's model. Thus,
// to set the contents for an inside label,
//    1) Get the BarChart's graph model
//    2) Call setInsideLabelContent() to set the label content
