Newbie just starting on charting with PHP - and seeking advice on options/approaches

Hello,

I am looking at options to chart dynamic data held in the PostgreSQL database pushed out to the web ‘pages’ via PHP, time series data in a scientific setting such as groundwater levels from a transducer…

I was seeking any input anyone might care to offer…

Initial searching found these:

• http://www.maani.us/charts/index.php (with newbie tutorial I found at http://www.developer.com/lang/php/article.php/3714046 )

• http://quimby.gnus.org/circus/chart/chart-manual.php

• http://www.amcharts.com/

• http://naku.dohcrew.com/libchart/pages/introduction/

• http://code.google.com/apis/chart/ (simple example explained here à http://james.cridland.net/code/google-chart.html )

• Or any other thoughts??

(I guess I could maybe pull together US$100 for licence if needed…)

I don’t need anything fancy, as the technical data analysis will be done inside the network with ODBC, etc… this is more for the less-technical web page user to see the data graphically… (much like they can see it spatially via MapServer…)

Thanks in advance!
