Open Flash Chart
Support This Project :: Home - Downloads
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.

Open Flash Charts is open source. So you get the source code of the chart to keep, this means that if you find bugs and need to fix them, you can. Or if you are worried that this website may dissapear, even if it does (don't worry, it won't), you have the code and can hire a flash programmer to fix any problems you have.

Don't forget to clear your browser cache when you have downloaded the Open Flash Chart files. This will remove any cruft that may cause you problems.

Open Flash Chart Licence:

Open Flash Chart is released under the GNU General Public License.

For a bit more info on copyleft and don't forget to check out Richard Stallmans, his ideals behind Copyleft: Pragmatic Idealism. And finally the GPL FAQ, should answer all your questions on what you can and can not do with the source. And lets face it, with it licenced under GNU GPL you can do a lot with it.

Commercial ventures may be interested in this question and answer.

PHP classes Licence:

The PHP classes are released under the GNU Lesser General Public License.

What does the LGPL mean? Well, lets start with the GPL. A commercial product may interact with a GPL product 'at arms length', this means you can not include GPL libraries in your code.

Open Flash Chart is a compiled flash object which communicates with the world by downloading a data file. This is 'at arms length' and means you can use it in a commercial product, so long as you inform your users that Open Flash Chart is GPL and provide access (e.g. a link) to the source code.

The LGPL allows you to include libraries of code into your commercial product. That is why I chose the LGPL for the PHP libraries.

Price:

Don't worry, Open flash Chart is free :-) but in return for all the hard work the development team have put into the code please, please take time to return the favor by doing one of the following:
  • Send us a message saying hello. Please include a photo of you in your local pub enjoying a beer.
  • Blog about Open Flash Chart. Help those of us who aren't very good at art by providing some beautiful example charts for us to copy.
  • Use the money you saved by downloading Open Flash Chart to take your [girlfriend|wife|boyfriend|husband] out for a beer and kebab.
  • Get involved! Send us code changes, ideas, bug reports or feature requests!
  • Use Open Flash Chart. Integrate it in other open source projects. Get it working on your blog showing visitor numbers, database activity, the number of comments by week, most popular stories and stuff like that. Show other people how to integrate it into their blogs. Write a plugin for your blogging software, then open source the plugin :-)
Thanks!


What is in the .zip file?

In the .zip file is the flash movie (which displays the chart) and the PHP library which is used in all the examples on this site. You also get the full source code for Open Flash Chart, these are the .fla files. I suggest you ignore them unless you are extremely curious.

To use Open Flash Chart upload the open-flash-chart.swf to your website. Then upload the PHP library folder to your website. Make sure all the permissions are set to allow the PHP to run OK. Then take a look at the examples on this site and make your own wonderful charts! Good luck!


If you like the charts, don't forget to Support This Project or buy advertising space.


The next version of Open Flash Chart is in alpha. But we need your help to find bugs and hack the libraries. Help us get it released faster! Open Flash Chart 2 alpha
Thanks!

Version 1.9.5

Changes since 1.9.4

This has some new charts:

  • candle (or whisker)
  • high, low, close
  • scatter (you can plot x,y points)

The new chart types do not have PHP libraries written yet. I have asked a few people to help me out and I will be coding too :-)

I have also given the pie charts some love, they now re-size themselves to make the most of the space available. The PIE used to be 60% and the labels just had to fit in, sometimes they fell off the chart area, and other times the chart had big blank areas. Now the PIE chart re-sizes its self so everything is 'just right' (tm) ;-)

We also have some .NET libraries which I AM SO HAPPY ABOUT!! This was the last major platform that we didn't support - so thanks to Raghunath T. (light .NET library) and Keith J. Kikta (big C# library).

Big thanks to:

  • Igor Antolic - high low close, advice and being so nice about my shoddy code :-)
  • Mayowa Akinyemi - Sponsored the candle chart
  • Ralph Daniel Tapac - PHP code

Changes since 1.9.2

I have broken the AJAX examples :-( this is because of the swfobject. I will try to fix these in the next release. If anyone can help I'd appreciate it :-) thanks.

  • Added clickable slices to the pie chart.
  • Bug report from Allan Cochrane: Fixed some bugs in the AJAX reload function.

  • We now have two Ruby libraries, one from Charlie at pullmonkey and the other from Arnold Cano, Director of Systems Development at www.mcmservice.com. Thanks guys!
  • Must mention sa0 who sent lots of bugs to me about the right Y axis - thanks dude!
