I am now using e4x as you suggest. I wrote a custom dataTipFunction to display the correct information.
I have tried many things, but I have not been able to get the X - axis labels working. How can I write a custom axis label rendering for the below code ? <?xml version="1.0"?> <!-- charts/HTTPServiceToXMLListCollection.mxml --> <mx:Application xmlns:mx="http://www.adobe.com/2006/mxml"; creationComplete="srv.send()"> <mx:Script><![CDATA[ import mx.utils.ArrayUtil; ]]></mx:Script> <mx:HTTPService id="srv" url="data.xml" resultFormat="e4x" /> <mx:XMLListCollection id="myAC" source="{srv.lastResult.result}" /> <mx:Panel title="Line Chart"> <mx:LineChart id="chart" dataProvider="{myAC}" showDataTips="true"> <mx:horizontalAxis> <mx:CategoryAxis categoryField="month"/> </mx:horizontalAxis> <mx:series> <mx:LineSeries yField="apple" name="Apple"/> <mx:LineSeries yField="orange" name="Orange"/> <mx:LineSeries yField="banana" name="Banana"/> </mx:series> </mx:LineChart> </mx:Panel> </mx:Application> On Thu, Jul 3, 2008 at 7:41 AM, Stephen More <step.........om> wrote: > On Wed, Jul 2, 2008 at 6:29 PM, Tracy Spratt <tsp.......com> wrote: >> I advise using resultFormat="e4x", a result handler function, and an >> instance variable to hold the xmlResult. > > I started out using e4x until I ran into what I think is a bug: > https://bugs.adobe.com/jira/browse/SDK-15976 > > DataTips in mx:LineChart does not like the e4x format. > > I guess I should go back to using e4x and write a custom > dataTipFunction that actually works. > > > -Steve > > >> The best performance, especially in a multi-renderer DataGrid, will be if >> you manually convert the XML node data ino an ArrayCollection of strongly >> typed value objects. >> >> >> >> Tracy >> >> >> >> ________________________________ >> >> From: [email protected] [mailto:[EMAIL PROTECTED] On >> Behalf Of Sean Clark Hess >> Sent: Wednesday, July 02, 2008 4:05 PM >> To: [email protected] >> Subject: Re: [flexcoders] Inspecting data from HTTPService result to an >> ArrayCollection >> >> >> >> Ah, got it. >> >> The <mx:Model> tag converts everything to a flat object.
