If you dont' see "graphics" under examples directory, it usually means
the MPE's graphics subpackge isn't configured for some reasons.  If you
check MPE's configure output, you should see reason why graphics subpackage
failed to configure.  In typical linux box, X11 headers or libraries are not
always installed that would prevent graphics subpackage from being built.

The most recent version of MPE user guide is the README file
https://svn.mcs.anl.gov/repos/mpi/mpich2/trunk/src/mpe2/README

Check MPE_CaptureFile and MPE_Update.
The visualization stuff has not been updated for years,
so it may not be able to do what you want.
