[ubuntu-uk] FLOSS solution for graphing in PHP

[Mark Harrison]

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.
