Disclaimer, I wrote Open Flash Chart with the help of lots of very kind people.
To generate the data for the chart to show you probably want a script on the server to grab data and format it. There are a number of these libraries, including:
Text file :-) the simplest way to show a chart is to point it at a text file on your server.
.NET (VB and C#)
Perl (in the download file and check on CPAN)
and we hope that we'll have an .asp one soon.
So please don't think this is a PHP application. It is a Flash movie that loads data from a file. This file can be generated by any of the above languages with about 5 lines of code.
Hope that helps, dudes.
