Hi, I've added a simple BarChart component to the ActionScript FlexJS SDK; it is modeled on the MX Charts package. I also included an example of using it, located in the FlexJS examples directory.
I developed the BarChart in ActionScript but it can be cross-compiled into JavaScript and produces the same chart. The BarChartExample has the sources in the project so that you can compile it for either ActionScript or JavaScript. I've included a README in that project with more information. The intent, as with the DataGrid, is to develop more complex components in ActionScript and cross-compile them into JavaScript, saving a lot of time. While doing this project I had to hand-craft a JavaScript component to display the bars since the ActionScript version relies on the Flash Player's Shape class and that is not available in HTML. I think this really illustrates the potential of FlexJS where you can have a good set of fundamental components that are environment specific (e.g., Button, Label, and TextInput) which must be crafted for all environments, but complex components can be written in ActionScript and just cross-compiled into JavaScript. My next task is add some simple axis labeling. Regards, Peter Ent Adobe Systems
