Hello, this is the Open Flash Chart project. Get graphs like this for free: 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. We also do pie charts. Why is that great? When the user downloads the web page, Open Flash Chart requests the chart data from the server. Add a bit of pizzazz to your bar charts! Is it complicated to set up? You will need to include the Open Flash Chart in your HTML, and you also need to provide the data file on the server. 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 make this a bit easier there are PHP, Perl, Python and Java classes to write the data file for you. Get started! Yes.
