I am new to the mailing list and to PostgreSQL.
I am currently running PostgreSQL 9.0.4 on a Windows XP laptop.
I am successfully logging sensor data to a database (temperature, humidity, voltage, etc…), I would like to display the data in a chart on a web site. Currently I am have everything on the same Windows system, PostgreSQL, data acquisition system, Apache Web server, pgAdmin III, and pgAgent....
If you are running PHP you can check out JpGraph. Not free but not too
expensive either and there are lots of chart options.
Sparklines might be just the ticket - especially for mobile devices. One
implementation is at http://sparkline.org/
Both the above are in PHP so you would need that on your system.
You could do something in JavaScript. gRaphaël is pretty cool:

And RRDtool makes nice graphs of sensor-type data:
