Chris, here's an example that uses your data format (in a file called "alldata.xml"). It uses e4x syntax to extract an array of names from the file, then creates a series for each of those names...
<?xml version="1.0"?> <!-- charts/XMLFileDataProvider2.mxml --> <mx:Application xmlns:mx="http://www.adobe.com/2006/mxml"; creationComplete="initApp();"> <mx:Script><![CDATA[ import mx.charts.series.LineSeries; import mx.charts.CategoryAxis; public function initApp():void { var wholist:Array = new Array(); for each(var property:XML in results.item.who) { wholist[property] = property; } for (var s:String in wholist) { trace(wholist[s]); var localXML:XMLList = results.item.(who==s); var localSeries:LineSeries = new LineSeries(); localSeries.dataProvider = localXML; localSeries.yField = "hours"; localSeries.displayName = s; var hAxis:CategoryAxis = new CategoryAxis(); hAxis.dataProvider = localXML; hAxis.categoryField = "when"; myChart.horizontalAxis = hAxis; var currentSeries:Array = myChart.series; currentSeries.push(localSeries); myChart.series = currentSeries; trace(localXML); } } ]]></mx:Script> <mx:XML id="results" source="alldata.xml"/> <mx:Panel title="Line Chart with Variable Number of Series"> <mx:LineChart id="myChart" showDataTips="true"/> <mx:Legend dataProvider="{myChart}"/> </mx:Panel> </mx:Application> hth, matt horn flex docs > -----Original Message----- > From: [email protected] > [mailto:[EMAIL PROTECTED] On Behalf Of Chris Alvarado > Sent: Tuesday, September 26, 2006 11:41 AM > To: [email protected] > Subject: [flexcoders] Line Chart > > Hello all, > > > > First time posting to the list here. > > > > I am working with the Line Chart component and having some problems. > > > > I am delivering the data through an XML document. > > > > I have: > > > > Employees > > Date > > Hours > > > > The selected dataset changes based on some input criteria > such as which employees to show. > > > > Ideally what I am wanting is to have a line that represents > each employee with a separate line. > > > > The x-axis will be the dates I have data for. > > > > And the y-axis will represent number of hours. > > > > At the moment my xml doc's format looks like this: > > > > <dataset> > > <item> > > <who>Some Person</who> > > <when>Some Date</when> > > <hours>Some Hours</hours> > > </item> > > </dataset> > > > > dataProvider="{myServiceGraph.lastResult.dataset.item}" > > > > First, I cannot seem to figure out how to get the graph to > display a dynamic number of lines based on how many <who> > elements I have. > > > > Second, it seems like I might even have the data arranged > incorrectly for what im trying to accomplish. > > Any ideas? > > > > Thanks for any help and im looking forward to some great > conversation on this list. > > ________________________________ > > I've stopped 4,856 spam and fraud messages.
