You can use GPRINT and COMMENT fields to place text into window beneath
the graph. You can't point to a peak with them, but it's appropriate
for longer text bits.
You can insert a VRULE in the graph to mark a point in time, and it can
be referenced in the graph legend. I wouldn't want to put a paragraph
in the legend, but maybe a short description ("May outage"), and then a
comment in the graph about the "May outage" would work.
