Multiple RRD graphs and text instance

Hi,

When creating custom graph from multiple RRD, every GPRINT and COMMENT are repeated for each FNPATTERN.
Is there a way to have text only written once.
Something like:
	(...)
	COMMENT:@RRDPARAM@ title
	GPRINT:val at RRDIDX@:LAST:%4.0lf
	GPRINT:val at RRDIDX@:MIN:%4.0lf
	GPRINT:val at RRDIDX@:MAX:%4.0lf
	GPRINT:val at RRDIDX@:AVERAGE:%4.0lf\l
	COMMENT:Last comment written only once
That will graph:
	param0 title 0 0 0 0
	param1 title 0 0 0 0
	param2 title 0 0 0 0
	Last comment written only once

TIA,
	Jo

It should only print once, but it depends on where you put it in the graph-definition.

Should be OK, if you write it *after* all of the DEF/CDEF/LINE/AREA definitions.

At least, that is how I think it works. Please post the full graphs.cfg definition.

What I would like is the "Cur/min/Avg/Max" line to appear only once at the beginning and the "new line" t appear only once at the end. Moving "COMMENT" section doesn't seem to do anything. Xymon is 4.3.9, compiled from sources on OpenBSD.

The graph is attached.

Henrik
