Dynamic data inside a chart's dataProvider

Question

Dear Members,
I am adding some extra touches to my application, it's basically a tool to give online presentations so I would like to add some charts for a more visual experience.
I am using the Flex Pie Chart that I create dynamically with actionscript:
private function createChart():void
     series = new PieSeries();
     series.nameField = "label";
     series.field = "data";
     series.filters = [];
     chart = new PieChart();
     chart.percentWidth =100;
     chart.percentHeight = 100;
     chart.showDataTips = true;
     chart.dataProvider = medalsAC;
     chart.series = [series];
     charts.addElement(chart);
The above code works fine, the problem is with providing the data for my chart. Below you can see that I created some variables in which I store data. Now the problem is that when I assign these variables like you see below, the chart won't show them. It only shows the static data (200) from the first product.
So I wonder what I am possibly doing wrong? I guess it's something very simple, but without those dynamic vars I can't use the charts.
private function setChartData():void
     var data2:uint = 200;   
     var data3:uint = 300;
     var data4:uint = 200;
     var arr:Array = [];
     arr.push({label:"Product 1", data: 200});
     arr.push({label:"Product 2", data:data2)});
     arr.push({label:"Product 3", data:data3});
     arr.push({label:"Product 4", data:data4});
     medalsAC = new ArrayCollection(arr);
     createChart();

I don't think Wayne is kidding at all.
You stated earlier: "But it is clear that Numbers resembles Excel."
In the very general sense (both are spreadsheet applications), that's true. But it is also clear that a Smart car resembles a Peterbilt tractor unit. Both have two axles, limited passenger seating and engines that require Diesel fuel. I wouldn't use either to do what the other is intended to do, nor would I expect each to behave exactly like the other.
You describe what you want to do as "something simple." It may well be "simple" (it certainly looks simple, and requires simple actions on the part of the user—in either application), but unless you have programmed that function, you have nothing on which to base the assumption that it is "simple."
Your original question was: "What is the equivalent in numbers?"
In the "simplest" terms possible: There is no equivalent in Numbers.
Wayne has described for you how to accomplish a similar result. You have explored and found  way to make the result closer to the result in Excel.
He has also given you the information on steps to take to suggest to Apple (rather that to the users in this community) that the method of achieving this result be improved.
That's about as far as it can go in this forum.
