disk partition not shown / global graphs problem

Hi,

I'm running xymon client on a debian linux. Some partitions are not graphed, but i've a dead link instead of additional graph. the test did correctly report all partitions, the only problem is the graph. I deleted the disk*rrd files in ~xymon/data/rrd/my_host/ the rrd file are created again, but my partition is still not on graph. I've same issue with other graphs, some are feeded by my own script, and almost every plugin I use are not correctly reported in graph (some values are in graph, others aren't).

Tks for any help
