Let's see...
1) If you're going to use binding to assign the dataprovider, and you
want to swap in a different one at runtime, you either need to a) change
the value of the thing you're binding to, or b) don't use binding. i.e.,
you could do this:
<Script>
[Bindable] public var currentDP:Array;
public function changeDP() {
currentDP = someOtherDP;
}
// Adding a series:
Function addSeries()
{
var newSeries:ColumnSeries = new ColumnSeries();
newSeries.yField = "newYField";
chartSeries.push(newSeries);
myChart.series = chartSeries;
}
</Script>
<ColumnChart id="myChart" dataProvider="{currentDP}" >
<series>
<Array id="chartSeries">
<ColumnSeries ... />
</Array>
</series>
</ColumnChart>
I'm not sure exactly what you mean by dragging a column. You mean
drag-select a group of columns to then drag/drop? Could be done, but it
would be non-trivial work. Selection unfortunately didn't make it into
this release. But you could extend the ColumnSeries and CartesianChart
to support it.
Additional Types: Yes, in theory, although nothing specific is planned
at this point. PieChart is built on PolarChart, which could serve as
the basis for any type of Polar Coordinate based chart. Which means a
RadarSeries shouldn't be too hard to build on the shipping Flex2 charts
(think of it as a LineSeries based on a PolarChart).

Subject: [flexcoders] Re: [Flex 2b2] Changing a Chart's dataProvider at
runtime?
Change it to a different one. (See below) For example:
change dataProvider (via AS3) for summaryChart to
"{model.marketSummary}"
add a ColumnSeries where yField equals "mktQTY" and categoryField equals
"mktLabel"
Thanks Ely! Also, while I've got you...
Any suggestion on how to drag a column as a way to select a group of
data to drop?
Are there any plans for additional chart types in the future? Radar
Chart?
