Info: Open Flash Chart 2 is out. Version 1.x and these pages will
never disappear and the charts will continue working forever, but further
development on 1.x has stopped. Take a look at version 2 here
Open Flash Chart 2.
Hello, this is the Open Flash Chart project.

How does it work?
User browses to your web site.
The browser downloads the web page which contains the Open Flash Chart.
Open Flash Chart downloads the data file and displays the chart.
When you add Open Flash Chart to your web page, you tell it where to find the data file.
When the user downloads the web page, Open Flash Chart requests the chart data from the server. The server
knows who the user is so it can generate a chart for that particular user showing up to the minute data.
You will need to include the Open Flash Chart in your HTML, and you
also need to provide the data file on the server. The data file is either a text file, or a .php, Perl, Python, Java (or another flavour of dynamic) page.
For a simple chart you would just drop the data.txt file on your website and point the Open Flash Chart to this URL.
But what we really want is dynamic data that is pulled from a database or calculated or something. To do this
you need to create the data file when it is requested. To do this we point the Open Flash Chart to a .php page and this PHP
page does your calculations and/or database lookups, then outputs the data file.
To make this a bit easier there are PHP, Perl, Python and Java classes to write the data file for you.
Why only these languages? Well any scripting language will do the same job. But I don't have access to anything but PHP. If anyone wants to translate the PHP class into a different language, then email me and I'll post your code and a link to your web site here.
The link to your site will be great for your page rank!
Yes. Once upon a time I had to deal with a company who sell flash charting components, their component
had a bug that I needed fixing, so I emailed them about it asking when it'd be fixed. (Remember that I had paid real money for this software.)
They were so incompetent, rude and obnoxious that after three or four weeks of emails I thought to myself "I could learn Flash and Actionscript and write
my own charting component, release it as Open Source, host it on sourceforge and build up a community of helpful coders faster than they can fix
a single bug." And that is what I did. And that is why it is free. I guess the moral of the lesson is: don't piss off your customers.

I am stuck with Flash 8 which is a bit naff. I would love to upgrade to Flash 9 with Actionscript 3.0 but I am
skint. So if you are rich and are looking to help out with this project click here!
