// To change the line style for needle lines:
//   1) Define a MarkerStyle for the plot markers
//   2) Get the RiskMapPlotModel and call its setInterpolationEnabled()
//      method to enable interpolation
//   3) Call the MarkerStyle's setInterpolation() method to set
//      the interpolation type
//   4) Define a LineStyle and call the RiskMapPlotModel's
//      setNeedleLineStyle() method to set the interpolation type
