Following up on my own posting. I got curious myself and did some testing. The result is attached to this message and will be stripped by listar. It should be possible to retrieve the files, they are: - grapher a bash script doing the work - numbers.rrd resulting RRD - index.html small but effective - allnumbers.png showing y=sqrt(x) for x = 0 .. 24 - lownumbers.png showing both y=sqrt(x) and y=x for x = 0 .. 5 The script is bash, it needs gnu-date. It should be easy to port it to, for instance, perl. Many comments, absolutely no warranty. cheers, Alex -- Attached file removed by Ecartis and put at URL below -- -- Type: application/octet-stream -- Size: 2k (2720 bytes) -- URL : http://www.ee.ethz.ch/~slist/p/grapher -- Attached file removed by Ecartis and put at URL below -- -- Type: application/octet-stream -- Size: 4k (4380 bytes) -- URL : http://www.ee.ethz.ch/~slist/p/numbers.rrd -- Attached file removed by Ecartis and put at URL below -- -- Type: text/html -- Size: 363 bytes -- URL : http://www.ee.ethz.ch/~slist/p/index.html -- Attached file removed by Ecartis and put at URL below -- -- Type: image/png -- Size: 55k (56792 bytes) -- URL : http://www.ee.ethz.ch/~slist/p/allnumbers.png -- Attached file removed by Ecartis and put at URL below -- -- Type: image/png -- Size: 63k (65124 bytes) -- URL : http://www.ee.ethz.ch/~slist/p/lownumbers.png -- 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
