Not natively, as Xymon is designed more around thresholding for alerting.
However as metrics are stored in rrd files, a separate task could be built
that read in rrds, calculates trends, and triggers status changes (man
xymon | grep modify) for those tests based solely on future expectations.

Long term, visual options like those at

useful as well.
