Hi Peter. About findDataPoints() - various series types optimize under the assumption that their data never overlaps (i.e., a columnSeries assumes its columns don't sit on top of each other, so you never need to see tips for multiple columns at once). As far as accessing the chart items...Tom is right, subclassing and exposing the charItems out of the renderData is the way to go. Ely. From: flexcoders@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of Peter Demling Sent: Friday, June 08, 2007 8:41 AM To: flexcoders@yahoogroups.com Subject: [flexcoders] Help - need to access all chartItems! (bug in findDataPoints()?) I'm trying to refer to all of my ColumnChart's chartItems at runtime, but findDataPoints() only ever returns 1 object in its hitData array, no matter how large I set the mouseSensitivity with dataTipMode="multiple" (I also get a compile-time error when trying to directly refer to the "items" array of my ColumnSeries, even though this array of chartItems exists at run time). So first off, any suggestions for how to refer to all currently displayed chartItems - without using findDataPoints - would be immensely helpful (it's the final piece in a quick-and-easy way to turn column highlights on and off, so I can post that when I solve this!). The larger issue is that there might be a bug in findDataPoints(), since - except for PlotChart - no chart I've found will display multiple dataTips in the same series. Below is the example from the Developer's Guide on dataTipMode, where I've set the mouseSensitivity to 10000 and replaced one of the BarSeries with a PlotSeries: you can see how it will only show multiple dataTips (as returned from findDataPoints) for the PlotSeries. Thanks for any advice! -Peter Demling Lexington, MA <?xml version="1.0"?> <!-- charts/DataTipsMultiple.mxml --> <mx:Application xmlns:mx="http://www.adobe.com/2006/mxml";> <mx:Script><![CDATA[ import mx.collections.ArrayCollection; [Bindable] public var expenses:ArrayCollection = new ArrayCollection([ {Month:"Jan", Profit:2000, Expenses:1500}, {Month:"Feb", Profit:1000, Expenses:200}, {Month:"Mar", Profit:1500, Expenses:500} ]); ]]></mx:Script> <mx:Panel title="Bar Chart"> <mx:CartesianChart id="myChart" dataProvider="{expenses}" showDataTips="true" mouseSensitivity="10000" dataTipMode="multiple" > <mx:verticalAxis> <mx:CategoryAxis dataProvider="{expenses}" categoryField="Month" /> </mx:verticalAxis> <mx:series> <mx:BarSeries yField="Month" xField="Profit" /> <mx:PlotSeries yField="Month" xField="Expenses" /> </mx:series> </mx:CartesianChart> <mx:Legend dataProvider="{myChart}"/> </mx:Panel> </mx:Application>
