You mean, at some point T you switched things round, and you want the graph to switch around as well ? Without going and looking stuff up (really busy right now), it's similar to the "I started a new RRD at time T and want to use the old one up to that point. I used something like : CDEF:aa=a,unkn,timestamp,t,lt,if CDEF:bb=b,unkn,timestamp,t,lt,if CDEF:cc=b,unkn,timestamp,t,ge,if CDEF:dd=a,unkn,timestamp,t,ge,if Then plot aa, bb:stack, cc, dd:stack For where I've put "timestamp", you'll need to check the docs, there's a function which returns "the timestamp of the value being processed". _______________________________________________ rrd-users mailing list rrd-users@lists.oetiker.ch https://lists.oetiker.ch/cgi-bin/listinfo/rrd-users
