One last comment: I don't know what you mean by "get rejected for the 
plots" -- you mean empty bins? Again, this is best done direct from the 
YODA data objects rather than what did or didn't result in a line being 
drawn on our plot, which depends on all sorts of details, like the 
aesthetic tastes of the make-plots author *and* the various .plot file 
authors.
