This would be possible but please consider the more generic approach: DEF:week1=rrdfile:ds:CF:time-range:steptime DEF:week2=rrdfile:ds:CF:time-range:steptime DEF:week3=rrdfile:ds:CF:time-range:steptime [... etcetera ...] LINE1:week3#FF0000:"Current week\n" SHIFT:604800 <--------------- this shifts the graphing, not the data LINE1:week2#00FF00:"Last week\n" SHIFT:1209600 LINE1:week1#0000FF:"Week before\n" This approach would also allow for: DEF:januari=rrdfile:ds:CF:time-range:steptime DEF:februari=rrdfile:ds:CF:time-range:steptime DEF:march=rrdfile:ds:CF:time-range:steptime PRINT:januari:AVERAGE:"Januari average: %6.2lf\n" PRINT:februari:AVERAGE:"Februari average: %6.2lf\n" PRINT:march:AVERAGE:"March average: %6.2lf\n" and, last but not least: DEF:januari=rrdfile:ds:CF:time-range:steptime DEF:februari=rrdfile:ds:CF:time-range:steptime DEF:march=rrdfile:ds:CF:time-range:steptime VDEF:percjan=95,januari,PERCENT VDEF:percfeb=95,januari,PERCENT VDEF:percmar=95,januari,PERCENT LINE1:januari#0000FF:"Januari data in\n" LINE1:februari#00FF00:"Februari data in\n" LINE1:march#0000FF:"March data in\n" LINE1:percjan#FF0000:"95th percentile for januari\n" LINE1:percfeb#FFFF00:"95th percentile for februari\n" LINE1:percmar#FF0000:"95th percentile for march\n" (possibly combined with SHIFTs to overlay last year) cheers, -- __________________________________________________________________ / [EMAIL PROTECTED] [EMAIL PROTECTED] \ | work private | | My employer is capable of speaking therefore I speak only for myself | +----------------------------------------------------------------------+ | Technical questions sent directly to me will be nuked.
