[Xymon] custom graph advice

Hello All,

I want to create a graph that plots a % based on a couple of entries
in a log file.  That, in itself, is not the problem.

My issue is that a new log file is generated each day but the java
garbage collection (which creates the log entries) doesn't run on a
schedule.

Therefore there will be times (from 00:00 most obviously) when no data
is returned.

When data is missing, should I leave it null, literally set it to NaN
or something else entirely?  For example, which of these is
recommended?

configured_max:
post_GC:

or

configured_max:NaN
post_GC:NaN

If something else, what should it be?
