This SWC flex component based on Open Flash Chart 2 (Kvasir) .

Other working example [Open Flash Chart 2 (Kvasir) - Explorer] Any feedback would be welcome.  

Bug fixed from previous version:

  • Stack Bar Chart  

Things not working in this component:

  • Pie Chart Tooltip

How to included SWC files:

In Flex 3.3 SDK – the files are included at flex-install-dir/frameworks/libs directory.

Note: I patched against the latest Open Flash Chart Version 2 Kvasir (16th, June 2009).

You can get more information about changes from previous posts.

Let me know if you need any help.

Open Flash Chart 2 as a SWC component - source code

Here is the source code for Open Flash Chart 2 as a SWC component.

Download [OFC2library-src] source code by WebASP.

Things i modified from original Open Flash Chart 2 (Jörmungandr-2)

Modified Files:

  • Loading.as
  • Tooltip.as
  • BackGround.as
  • Keys.as Title.as
  • YAxisBase
  • YAxisLeft
  • YAxisRight
  • XLegend.as
  • YLegendBase
  • YLegendLeft.as
  • YLegendRight.as
  • Menu.as

so what i modified, add new two extra parameter to all classes that using “stageWidth” and “stageHeight”(pWidth:Number,pHeight:Number). Open Flash Chart 2 used lot of “stageWidth” and “stageHeight” to draw chart. As it only get size of main drawing area (EG: most times we need chart less than the size of the container and we have other elements around). Above modicifation accept width/height values from the parent container and size itself accordingly.

  1. pWidth —— Parent Width
  2. pHeight —- Parent Height

New Added File :

Chart.as(as it only work as to generate flex component) : From main.as with some changes. I didn’t add any comments in it, most things are understandable.

    Stack Bar Chart Pie Chart Tooltip

How to included SWC files:

In Flex 3.3 SDK – the files are included at flex-install-dir/frameworks/libs directory.

Sample code: 

<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" xmlns:ofc="*" width="100%" height="100%">
   <mx:Script> <![CDATA[
   [Bindable]
   private var dataJSON:String='{ "elements": [ { "type": "bar","alpha":0.8,"colour":"#663366", "values": [ 9.5, 9, 8.5,8, 7.5, 7, 6.5, 6, 5.5,5, 4.5, 4, 3.5, 3, 2.5, 2, 1.5, 1 ] } ], "title": { "text": "Wed May 20 2009" },"bg_colour":"#fcfcfc" }';
   ]]></mx:Script>
   <mx:Panel id="chartContainer" title="Flex Chart" width="100%" height="100%">
    <ofc:Chart id="myChart" width="900" height="600" loadingString="Loading..." chartData="{dataJSON}"/>
   </mx:Panel>
</mx:Application>

Note:

  • If you change the chartData it will automatically reload the chart.
  • If you change width and height after chart load you need to call “myChart.load();” to reload the chart to right size.
