[flexcoders] Re: converting a Java object into a chart dataprovider
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 the flex documentation, it shows how to easily create a chart with
mxml and a static Array:
private var expenses:Array = [
{Month:January,Profit:2000,Expenses:1500,Amount:450},
{Month:February,Profit:1000,Expenses:200,Amount:600},
{Month:March,Profit:1500,Expenses:500,Amount:300},
];
mx:ColumnSeries
xField=Month
yField=Profit
displayName=Profit
/
mx:ColumnSeries
xField=Month
yField=Expenses
displayName=Expenses
/
But I am reading my data from the database and want to pass the data
via a
java object. But I don't know the number of fields at runtime. So how
do I
assign the xFields and yFields since I won't be able to create a
variable
named Month or Profit? I'll just have an array of floats or dates
or
whatever. Here's a start put I have no idea how to plug in the missing
pieces or if another route would be preferable.
var lineSeries:LineSeries = new LineSeries();
BindingUtils.bindProperty(lineSeries, dataProvider, ser,
javaArray);
// lineSeries.xField= ???
// lineSeries.yField= ???
The data set is often quite large by the way.

[flexcoders] Re: converting a Java object into a chart dataprovider
In the previous implementation, I would send an ArrayList of custom Objects
containing two values each, variables called point1 (an Object) and point2 (a
float). So for each series, I'd assign this ArrayList (converted into an
ArrayCollection by blazeDS) as the dataProvider for the series and xField =
point1 and yField = point2.
Obviously if I had many series on the same axis, the xField data would be
duplicated for each series (very redundant, I realize). In the new
implementation, I'd like to just have all the xFields point to a single array
of dates for example and then each yfield would point to a different array.
But since I can't create an Object in Java on the fly with variables called
point1, point2, point3, etc, I'm at a loss as how to get flex to
recognize where my data is when I assign the dataProvider.
I hope that makes more sense.

Re: [flexcoders] Re: converting a Java object into a chart dataprovider
Assuming Blaze or LiveCycle to create an object that is rendered as an
actionscript object with subobjects use a map. Maps are serialised as
simple objects.

Re: [flexcoders] Re: converting a Java object into a chart dataprovider
The last poster beat me to it, but yes, the answer is an array of Maps in
Java, should come through as a simple assosciative object in ActionScript.
