  @hawu this gives the following compilation warning with clang:

  ../UT/UTCheckers/src/UTDigitMonitor.cpp:88:73: warning: implicit conversion from 'double' to 'unsigned long' changes value from 764.8 to 764 [-Wliteral-conversion]	
      plot2D( hitX, hitY, "UTDigits X vs. Y", 4, -908.6, 908.6, -764.8, 764.8, 76, 32 );	
      ~~~~~~                                                            ^~~~~

  Are you sure the arguments of plot2D are correct? I think the ID argument (4) should be before the title?
