Seiwert<mailto:r...@vcaglobal.com> Subject: [GRAYMAIL] RE: Re: Re: RE: RE: Question about trend line I somehow ended up with desired output and used your way for equation for getting a number a process it in CDEF to get the final line. CDEF:trend=dt_month,POP,$COEF,COUNT,* \ $COEF is my final previously calculated number that is close to "24" when you print it, but I still have doubts about that number. How to get "step width" that you mentioned? Playing with numbers I found that "19500" as step width, gives proper line direction, but gives me no clue why 19500. This is rather match question but I would still appreciate your comment on that. thanks [http://rrd-mailinglists.937164.n2.nabble.com/file/n7583100/trend3_rrd.png] ________________________________ If you reply to this email, your message will be added to the discussion below: http://rrd-mailinglists.937164.n2.nabble.com/Question-about-trend-line-tp7583077p7583100.html To start a new topic under RRDtool Users Mailinglist, email ml-node+s937164n937053...@n2.nabble.com To unsubscribe from RRD Mailinglists, click here<http://rrd-mailinglists.937164.n2.nabble.com/template/NamlServlet.jtp?macro=unsubscribe_by_code&node=937164&code=cm9iQHZjYWdsb2JhbC5jb218OTM3MTY0fC0yMTE0MzU4MzIz>.
