Right. I'd like to basically return an array of arrays, visually organized like a spread sheet. So the xField might point to column 0 (the first array) and yField to column 1. For then next series, xField would still be column 0 and yField would be column 2, etc.
As far as the actual way to pull this off in java, I'm not sure how to do it in a way that flex will recognize as an associative array (like the Month:"January", Profit:2000, Expenses:1500, Amount:450 from the first example). --- In [email protected], Josh McDonald <j...@...> wrote: > > But what will the objects be that you're sending back?
