graphs not showing on column but are in trends

I've got a strange problem with a new graph. I've added the graphs.cfg entry
and it's named the same as the column on the Xymon display

 
[vs_stat]

        FNPATTERN vs_stat.(.*).rrd

        TITLE Connections

        YAXIS Connections

        DEF:conn at RRDIDX@=@RRDFN@:ds0:AVERAGE

        LINE1:conn at RRDIDX@#@COLOR@:@RRDPARAM@ Conn

        GPRINT:conn at RRDIDX@:LAST: %8.2lf %s (cur)

        GPRINT:conn at RRDIDX@:MAX: %8.2lf %s (max)

        GPRINT:conn at RRDIDX@:MIN: %8.2lf %s (min)

        GPRINT:conn at RRDIDX@:AVERAGE: %8.2lf %s (avg)\n

        -l 0

 
I've added it to TEST2RRD and GRAPHS in xymonserver.cfg (TEST2RRD entry is
vs_stat=devmon and GRPAHS is vs_stat::1)

 
All is working as expected except that the graphs are only showing in the
trends column and not in the vs_stat column. I based all this work on the
if_load definitions for a cisco 6509 from the standard devmon templates and
that does show on the of_load column as well as the trends column but my new
on doesn't. 

 
Has anyone any idea what the issue might be?
