PHP charting library

Question

I'm looking for a PHP chart library, with a few specific criteria:

• I can't use Google charts because, in at least one case, I need to be able to run on a private network with no internet access (ergo no Google).
• I need to be able to produce bitmapped images (png, etc). SVG would also be nice, and Flash is acceptable as an extra, but the static bitmapped images are necessary (so a completely Flash chart would be unusable).
• Open source preferred but commercial is acceptable.

Answer 1

Take a look at:

Answer 2

I would recomment Flot - it's a client-side (javascript) charting library, but it does not requite an internet connection (you can host everything on the intranet). If you want a PHP wrapper for it, many frameworks come with it - for example, here's one for QCubed, the framework that I use: http://examples.qcu.be/assets/plugins/QFlot/example/qflot-timeseries.php

Answer 3

Try this new stuff: http://www.highcharts.com/ written in javascript

Answer 4

• Open Flash Chart
• Google Chart API
