// ReverseAxis:

// To reverse the axis, do both of the following:
// 1) Set the axis ranges in reverse order for the reverse axis values
// 2) Set the appropriate color values for the risk map
// 3) Use the RiskMapPlotModel to get the axis model, and then call the 
//    returned model's setReverseDirection() method with the value true
