It is your interpretation. What the manual tries to tell you is: You can stack on top of an AREA or on top of a LINE. The STACK will behave as if you repeated your last command (i.e. AREA or LINE) but with an offset. > Because I don't understand how a STACK can be "either a LINE? or an AREA". > (Does it make sense to stack lines ??) If you do DEF:ifin_min= ... DEF:ifin_max= ... CDEF:ifin_diff=ifin_max,ifin_min,- LINE1:ifin_min#00CC00 STACK:ifin_diff#FF0000 then you're really doing nothing more than graphing ifin_min and ifin_max. In *this* example, it is completely useless of course. It is nothing more than: DEF:ifin_min= ... DEF:ifin_max= ... LINE1:ifin_min#00CC00 LINE1:ifin_max#FF0000 I'm sure someone can come up with an example that's less useless. The developers release knows how to do what you want; it can stack an AREA on top of a line. Please try it out if you dare and do give feedback. cheers, Alex -- Unsubscribe mailto:[EMAIL PROTECTED] Help mailto:[EMAIL PROTECTED] Archive http://www.ee.ethz.ch/~slist/rrd-users WebAdmin http://www.ee.ethz.ch/~slist/lsg2.cgi
