Re: [ubuntu-uk] FLOSS solution for graphing in PHP
Thanks to all who responded - it looks like Alan's suggestion of gd is probably what I need. rrdtool looked interesting, but the home is pretty much all xAP/xPL stuff, not least because the HomeVision connector was the first GPL application I ever released :-) Time was (about 2002) when I logged every telemetry event in the house (temp changes, lights on-off, occupancy sensors, etc) for about 2 months into a MySQL database - trouble was, 1: I couldn't work out what to do with the data set, and 2: we had kids :-) I still have a ludicrous amount of home automation hardware sitting on a shelf in the study awaiting the day when I'll get the fabled Round Tuit and set it up in a child-friendly way. Too many interesting projects, not enough time. GD - good call, though. Seems to be what I need. M.

Re: [ubuntu-uk] FLOSS solution for graphing in PHP
There's a perl module that makes graphs - I think it's used in the wifidog system I use for wireless auth to create user stats. http://cpan.uwinnipeg.ca/htdocs/GDGraph/GD/Graph.html Chris -- ubuntu-uk@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-uk https://wiki.kubuntu.org/UKTeam/

But if you want to work at that low level, imagemagick could be what you need. -- Alec Wright -- ubuntu-uk@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-uk https://wiki.kubuntu.org/UKTeam/

An example of rrdtool can be seen if you ever view cacti performance and other resource usage graphs. You can see an example on the front page of the cacti site. http://cacti.net/ Cheers, Al. signature.asc Description: This is a digitally signed message part -- ubuntu-uk@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-uk https://wiki.kubuntu.org/UKTeam/

Have a look at my brother in laws temperature graphs - http://www.hoagieshouse.com/temperature/ Thats the sort of thing you get - you can of course tweak them a bit too. A cron job gets the data every x seconds and adds the next point to your graph. Mark -- ubuntu-uk@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-uk https://wiki.kubuntu.org/UKTeam/

I think imagemagick might help, but I'm not sure...
