Hey guys, I'm having a problem I think may be a bug.. It has to do with the category axis on a column chart when using XMLListCollection as a dataProvider.
Basically what I see is that if I use an actual data set (one of the data providers from a series) as the category Axis dataProvider, the labels show correctly. However if I pass an XMLList containing a list of Simple elements containing the strings (or even just an array of strings) for the category axis dataProvider, the labels don't show at all. The documentation for CategoryAxis says: "The dataProvider property can accept either an array of strings or an array of records (objects) with a property specifying the category name. If you specify a categoryField property, the CategoryAxis assumes the dataProvider is an array of Objects. If cateogryField is null, the CategoryAxis assumes dataProvider is an array of Strings." It seems like this should work. I cannot seem to make it work. Below you can find a sample application and populateChart function which demonstrates the problem. I have commented out the working two lines, and the other two lines which exibit the problem are below it. Thanks in advance, Thunder __________________________ <?xml version="1.0" encoding="utf-8"?> <mx:Application width="100%" height="100%" xmlns:mx="http://www.macromedia.com/2005/mxml"; xmlns:root="*"> <mx:ColumnChart id="mainChart" width="403" height="232" /> <mx:Button label="Fetch" click="populateStaticChart()"/> <mx:Script> <![CDATA[ import mx.collections.ArrayCollection; import mx.collections.XMLListCollection; import mx.charts.series.ColumnSeries; import mx.charts.CategoryAxis; public function populateStaticChart():void { var oData:XMLList = null; var oXML:XML = <data> <row> <Platform>Convergence</Platform> <Year>2005</Year> <PageConvergenceMSMUnits>3.654</PageConvergenceMSMUnits> </row> <row> <Platform>Convergence</Platform> <Year>2006</Year> <PageConvergenceMSMUnits>4.3</PageConvergenceMSMUnits> </row> <row> <Platform>Convergence</Platform> <Year>2007</Year> <PageConvergenceMSMUnits>4.972</PageConvergenceMSMUnits> </row> <row> <Platform>Convergence</Platform> <Year>2008</Year> <PageConvergenceMSMUnits>16.117</PageConvergenceMSMUnits> </row> <row> <Platform>Convergence</Platform> <Year>2009</Year> <PageConvergenceMSMUnits>27.248</PageConvergenceMSMUnits> </row> <row> <Platform>Convergence</Platform> <Year>2010</Year> <PageConvergenceMSMUnits>29.56</PageConvergenceMSMUnits> </row> </data>; oData = oXML.row; var oXMLCol:XMLListCollection = new XMLListCollection(oData); var aYears:Array = [ "2005","2006","2007","2008","2009","2010" ]; // add the category axis to the chart var hAxis:CategoryAxis = new CategoryAxis(); // ***** this works ***** //hAxis.categoryField = "Year" ; //hAxis.dataProvider = oXMLCol; // ***** this doesn't ***** hAxis.categoryField = null ; hAxis.dataProvider = aYears; hAxis.name = "Year" ; mainChart.horizontalAxis = hAxis; // add a series to the chart and try to use the XMLListCollection as the DP var sa:Array = mainChart.series var cSeries:ColumnSeries = new ColumnSeries(); cSeries.yField = "PageConvergenceMSMUnits" ; cSeries.name = "Convergence"; cSeries.dataProvider = oXMLCol; // cSeries.stackField = "PageConvergenceMSMUnits"; sa.push( cSeries ); mainChart.series = sa; } ]]> </mx:Script> </mx:Application> -- Flexcoders Mailing List FAQ: http://groups.yahoo.com/group/flexcoders/files/flexcodersFAQ.txt Search Archives: http://www.mail-archive.com/flexcoders%40yahoogroups.com Yahoo!
