The Memory Map, located at the upper left of the heap analyzer screen,
  displays a graphical representation of memory use in real time.

  Each memory allocation appears as a colored strip, or 'segment'.  By
  searching for segments that seem too large, too numerous, or in other
  ways anomalous, you can identify areas in your application where one of
  the following memory events may be occurring:

   -  Memory leaks

   -  Fragmentation

   -  Repetitive allocations

   -  Insufficient allocation

   -  Inefficient memory use

  For information on Memory Map context-sensitive pop-up menus and
  pull-down menus, see the additional topics below.

  For information on other heap analyzer screen locations and pop-up
  menus, click the 'On Context' menu item in the heap analyzer Help menu,
  then click the location of interest.

  For information on using the heap analyzer, see the 'On Window' menu
  item in the heap analyzer Help menu.
