Hi,
I am using chart in delta mode, for my routers interface oid only give me bytes counts, and not rate.
After each reconnexion of equipment, the first data collected leads to a huge delta, for the preceeding value was 0 for the dude.
THat seems logical, but spoiling the scale of the chart, and making them often unreadeable. Of course one can modify the eroneous data directly in the data source, but isn’t any trick to avoid this ?
I tought of a little function to smooth that (like : if value(n-2)=0, then make value(n-1)=value(n)), but do not know how to access the data source values from a function.
Any idea anyone ?
