You could quite easily create a year graph and use a imagemap to divide it into 12 sections. If one of the sections gets clicked you could generate a zoomed in version, again divided by an imagemap. And so on.
Thiss way you have an easy interface and you can zoom in on any part you're interested in. Place a zoom out and reset button under the graph and bingo, you're there! Serge. (basic setup: use epoch timestamps to define start and end of the graph. Use hidden fields in the form to store them. If timespan is a year (31536000 secs), divide the graph in 12 parts, if it's a month, divide in 4 parts, week=7 parts, day=24 parts, hour=4 parts...) -----Original Message----- From: Reinhard Weissenbrunner [mailto:[EMAIL PROTECTED] Sent: vrijdag 22 maart 2002 4:15 To: [email protected] Subject: [rrd-users] Defining the time range via HTML Form hi folks, Is someone graphing a "customized" time range from rrd-files ? I am thinking of a "HTML-Form where you can select "start" and "end" time and then, generating and displaying the png file as "result".. in fact, "end" will be equal "now" in most cases, but the "start" value could easily defined, since rrdtool graph accepts values like "-4h, -4d, -4w".. the RRDTool backend is working fine, and a html-form based frontend would be great, especially for "zooming" in to interestning time segments.. It seems to be the right challenge for a perl-newbie like me... Every hint or tip is highly apreciated.. <swoosh - perl-books crashing against my head>.... ok ok. :-) a few examples: http://www.access.at/reinitest/ cheers Reini -- 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 -- 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
