Hi Deepak, I didn't test, but since Datatips are managed at the chart level, not at the renderers level, (check ChartBase.mouseOverHandler() ), then it likely that simply adding click/tap listeners to the renderer will not work.
Did you try setting mouseSensitivity property for the chart ? http://help.adobe.com/en_US/FlashPlatform/reference/actionscript/3/mx/charts/chartClasses/ChartBase.html#mouseSensitivity Maurice -----Message d'origine----- De : Deepak MS [mailto:megharajdee...@gmail.com] Envoyé : mercredi 27 août 2014 11:46 À : users@flex.apache.org Objet : Lineseries tooltip on mobile Hi there, I'm using a columnchart with a lineseries in it for an ipad app. I have enabled tooltip for it. But unfortunately its too difficult to get the tooltip on the device when we move the finger over it. Hence I planned to add a custom circleitemrenderer with width and height of 20 to get the custom tooltip by adding a click\touchtap event on it. But unfortunately, it is not triggering the click\touchtap event at all. My code: myLineSeries.setStyle('itemRenderer', new ClassFactory(DataPointRenderer)); public class DataPointRenderer extends CircleItemRenderer { public function DataPointRenderer() { super(); width = 20; height = 20; addEventListener(MouseEvent.CLICK, onClick); addEventListener(TouchEvent.TOUCH_TAP, onClick); addEventListener(MouseEvent.MOUSE_OVER, onOver); } private var model:ApplicationModelLocator = ApplicationModelLocator.getInstance(); private function onOver(event:MouseEvent):void { model.showAlert('over'); /// This function is not at all called even after clicking(both on simulator as well as on device) } private function onClick(event:MouseEvent):void { model.showAlert('clicked'); /// This function is not at all called even after mouse hover (on desktop simulator) } override protected function updateDisplayList(unscaledWidth:Number,unscaledHeight:Number):void { super.updateDisplayList(unscaledWidth, unscaledHeight); var currentFill:uint; var g:Graphics = graphics; g.clear(); if (data is ChartItem && data.hasOwnProperty('fill')) { currentFill = data.fill.color; g.beginFill(currentFill); g.drawCircle(5,5,20); g.endFill(); } } } Am I missing something here?
