[Xymon] Graphs on dailup hosts

[Oliver]

Dear All,

if a dailup host is not online, the graphs for the downtime are white. 
Is it possible to clear out that white portion so that an ongoing line 
is shown? Monitored client systems with a low uptime just show some 
small dots, for example on the disk usage graph.

The ongoing line in that graph should show the tracked data for the 
amount of uptime. E.g. the 48h disk usage graph shows the usage for the 
last 48h uptime and not for the real time. How can I easily accomplish this?

Thanks!
Regards
