The format wasn't the issue alone, there was another reason copying 
fetch instead of xport (which I don't clearly remember) for this.

Anyway, if it provides the same convinience as fetch using rrdtools' 
buit-in intelligence on timeframes, resolution, etc... delivering only 
the data needed for *this* graph -> it sounds good ;)

best regards


BTW: to see this "live" and maybe understand why I care about 50ms (*20 
graphs: its a clearly visbible delay of 1 second):
