// ChangeAxis:

// A graph's display properties (axis characteristics, orientation, and
// so on) are general properties that are defined in the graph's model.
// Thus, to change a BarChart's axis characteristics,
//    1) Create an AxisModel and any other objects needed to define
//       axis characteristics (line style, tick intervals, ...)
//    2) Use the BarChart to set the axis definitions on the chart
// This example creates a StrokeLineStyle to define a
// 3pt solid red line for both the Category and Response axes.
// It creates an AxisModel to suppress the axis label and define
// a line style and tick characteristics for the Response axis.
