Is there any opensourse, free set of components for creating Flex mxml graphs?
like aviary Peacock style ones
with at least Drag, drop, and connect generators
so each graph element could have
or something like that.
Framework should be opensource (like GPL, LGPL etc)
BTW: I found one wary bacic made by Erno Aapa with Degrafa but I would really love to see something much more Flex 4 - mxml oriented and frienfdly.
So blog articles, Google code projects, anything - please help
I don't have a specific answer for you; but just some places to go look.
Have you looked at the Advanced Charting and Visualization package from Adobe? They are part of the open source SDK with the release of Flex 4.
You already mentioned Degra. I understood that Degrafa stands for Declarative Graphics. I'm surprised you'd say it is not MXML friendly.
Have you looked at Axiss? It is another project out there, and I believe it relies heavily on Degrafa.
You said open source, but didn't say free. So, I believe source code is available if you purchase a license to iLog. I'm not sure about FusionCharts, but I've heard very positive things about it from other Flex Developers.
Moccasin and Flex Wires combined should get you most of the way there.
