I believe the reason so many things are styles in charting is so that you can use a styleFunction to set properties on a chart embedded in an AdvancedDataGrid. IMO they should have overloaded things we expect to see as proprties so that they would act consistently with the rest of the framework but could still be set up via styleFunction. -Amy
Re: [flexcoders] Re: Getting a reference to a itemRenderer of a chart series
The question here is not if charts uses styles for itemRenderers or not - it´s fact, it really uses it. It´s working like this: I created my CustomItemRenderer extending BoxItemRenderer and I´m setting the series itemRenderers with setStyle method, like this: //For each columnSeries series.setStyle(itemRenderer, new ClassFactory(mx.charts.renderers.CustomtemRenderer)); See also: http://livedocs.adobe.com/flex/3/html/help.html?content=charts_formatting_12.html It´s working, I repeat. But the question was how can I get a reference for the series itemRenderes. On execution time, I have to modify an attribute of the itemRenderes than, when the updateDisplayList is executed again, the renderer will modify the draw made on each column (based on the attribut setted). If I use serie.getStyle(itemRenderer), it will return the ClassFActorty, not the itemRenderer. So, any idea people? -- Fernando Benedet Ghisi
[flexcoders] Re: Getting a reference to a itemRenderer of a chart series
Not arguing with you, but why would you use setStyle instead of: mx:ColumnSeries id=mySeries itemRenderer=mx.charts.renderers.CustomtemRenderer/ Does mySeries.items[0] not give you a reference? -TH --- In flexcoders@yahoogroups.com, Fernando Ghisi [EMAIL PROTECTED] wrote: The question here is not if charts uses styles for itemRenderers or not - it´s fact, it really uses it.

Re: [flexcoders] Re: Getting a reference to a itemRenderer of a chart series
When you do this in a MXML, I almost sure that it will be transformed on a setStyle(itemRenderer, ...) in actionscript. There is no other way of doing this on actionscript. To apply a renderer to a series in ActionScript, you use the setStyle() method. In that method, you create a new ClassFactory and pass the renderer to its constructor. Flex generates an instance of this class to be the renderer. Be sure to import the appropriate classes when using renderer classes. But you gave me a solution - when I set the itemRenderer for one serie, in fact I´m setting the itemRenderer for all items of this serie. So, I can really get a reference using the serie´s items array, like you said or, more especificaly, like this: CustomItemRenderer(ColumnSeriesItem(ColumnSeries(chart.series[index]).items[index]).itemRenderer That was easier than I thought it was.
