If you set a breakpoint in the debugger in your myFillFunction method
below and you inspect element:ChartItem, what is in the item property?
It should be the object corresponding to that datum in the data
provider you have attached to the chart. From there you should be
able to get at whatever you want in your domain model.
Not wishing to sound didactic, but how about having a copy of the Flex
language reference on your desktop? If you don't already have it as
part of your install then you should be able to download it from the
web. If you can't find it send me a message at simon dot palmer at
gmail dot com and I'll zip it up and send it to you. I find it a real
shortcut.
I also really recommend spending a day or two poring over the code on
sites like Ely Greenfield's quietlyscheming.com, Peter Ent's blog at
Macromedia, Alex Harui's Flex Closet and the flexlib at google. There
are a million resources free on the web with clever ideas and code
samples.
