HTTPService in ActionScript

Question

I'm writing a service call in Actionscript (httpservice) and
it doesnt seem to work as expected. I've looked around and haven't
found anything that really explains this seemingly simple task, but
some that come close. I'd appreciate some help.
I have a php call that will pass an XML data file.
First my imports:
import mx.events.*;
import mx.rpc.events.*;
NOTE: I cant seem to get mx.rpc.http.httpservice to import...
weird error occurs... anyone know why?
Next, my service call, which occurs in a for loop (that seems
to matter to the posts I've been reading):
var DBService:HTTPService = new HTTPService;
DBService.url = "
http://192.168.11.12/getdata.php?length=day";
var DB_data:Object = new Object();
DBService.send(DB_data);
Then I try to use the data:
var _newChart:LineChart = new LineChart;
_newChart.percentHeight = 92;
_newChart.percentWidth = 100;
_newChart.showDataTips = true;
_newChart.x = 0;
_newChart.y = 0;
_newChart.dataProvider = DB_data.lastResult.data.point;
_newPanel.addChild(_newChart);
I've tried using both the service call and the object as that
data provider, but it errors every time. Anyone have some
experience with this? Seems like thistype of thing would be a
fairly common tool, but I haven't seen it used.
Thanks.

Okay, so I've tried to simplfy my code (taking out for loops
for a proof of concept) and the graphs still don not populate...
My code is below:
public var obj:Object = new Object;
private function
useHTTPservice(param:Object,URL:String,result_fxn:Function=null,result_format:String="e4x "):void
var contact:HTTPService = new HTTPService();
contact.resultFormat = result_format;
contact.url = URL;
contact.method = "POST";
if (result_fxn != null ) {
contact.addEventListener("result", result_fxn);
contact.addEventListener("fault", httpFault);
contact.send(param);
private function dataReceived(evt:ResultEvent):void
obj = evt.result.data.point;
Alert.show("succss");
//_newChart.dataProvider = evt.result.data.point;
private function httpFault(evt:FaultEvent):void
Alert.show("fail");
private function configkiosk(event:ResultEvent):void
// sets up the base page
MainCanvas = new Canvas();
MainCanvas.id = "Main Canvas";
MainCanvas.width = 860;
MainCanvas.height = 800;
MainCanvas.setStyle("backgroundColor","white");
MainCanvas.setStyle("horizontalCenter","0");
MainCanvas.setStyle("verticalCenter","0");
this.addChild(MainCanvas);
var _newPanel:Panel = new Panel;
_newPanel.percentHeight = 100;
_newPanel.percentWidth = 100;
_newPanel.x = 0;
_newPanel.y = 0;
_newPanel.setStyle("borderStyle","none");
_newPanel.setStyle("horizontalAlign","center");
MainCanvas.addChild(_newPanel);
var _newChart:LineChart = new LineChart;
_newChart.percentHeight = 100;
_newChart.percentWidth = 100;
_newChart.showDataTips = true;
_newChart.x = 0;
_newChart.y = 0;
_newPanel.addChild(_newChart);
var DB_Connect:Object = new Object;
var URL:String = new String;
URL = "
http://192.168.11.12/getdata.php?length=day"
useHTTPservice(DB_Connect,URL,dataReceived);
//horizontal axis
_newChart.dataProvider = obj;
var _newSeries:Series = new Series;
var line:LineSeries = new LineSeries;
_newChart.addChild(_newSeries);
var lineStroke:Stroke = new Stroke();
lineStroke.color = 0xFF9900;
lineStroke.alpha = 1;
lineStroke.weight = 2;
line.setStyle("linestroke",lineStroke);
line.yField = "CO2_BDROOM";
_newSeries.addChild(line);
}
