After you generate histograms or tables, you can
  examine the results by interpreting the information
  collected from the perspective of your program's
  structure. You can navigate, or traverse, around
  the program's structure to view the areas with the
  most data points (the "hotspots") along with their
  corresponding source lines.

  The following are the navigation buttons:

  o  Next Hotspot

  o  Previous Hotspot

  o  First Hotspot

  o  Last Hotspot
