Hello Dan, Thanks for your quick response. I really appretiate that. I included an attach with two files inside:
the RRD called 379.framerelay1.rrd a perl script called graph.pl This file generate the graphs for the tests. The small graph use (500x150) and the big graph use (800x300) I used "step=300:reduce=MAX" and "step=300" alone with no success, but the graphs is a little bit better than with or widthout "reduce=MAX". reduce=MAX is used for pixel reduction technique and is not related to consolidation function used to fetch data; am I right ? Is this a Bug ? Thanks, Alejandro Galue.
