Question

I have a flex pie chart:

    <mx:PieChart alpha="0.9" fontSize="{QPieSeries_font}" width="100%" top="20" height="320" id="QPieChart" 
                 dataProvider="{dataObj}" horizontalCenter="0" color="0xFFFFFF" fontFamily="MyriadWebPro" 
                 showDataTips="true" dataTipFunction="QdataTipFunction" 
                 dataTipItemsSet="true" itemClick="QPieChart_itemClickHandler(event)">
        <mx:series>
            <mx:PieSeries id="QPieSeries" labelField="Answer" field="Value" labelPosition="callout"
                          showDataEffect="QSeriesInterpolate" alpha="1"
                          reserveExplodeRadius="0.05"/>
        </mx:series>
    </mx:PieChart>

where the QSeriesInterpolate is a simple interpolation given in the declaration:

<fx:Declarations>       
    <mx:SeriesInterpolate id="QSeriesInterpolate" duration="500" />
</fx:Declarations>

and the item click event looks like:

protected function QPieChart_itemClickHandler(event:ChartItemEvent):void
        {
                var ExAr:Array = [];
                ExAr[event.hitData.chartItem.index] = 0.05;
                QPieSeries.perWedgeExplodeRadius = ExAr;
        }

Basically, what annoys me is that when I click a segment to activate the interpolated event, the datatips disappear for it’s duration. Whilst this is only half a second, it still detracts from user experience. Is there anything I can do to avoid it??

ALSO! Another thing: Is it obvious to anyone why my dataTipFunction doesnt work? It looks as follows:

            public function QdataTipFunction(hitData:HitData):String
        {
            var a:String = "abc"
            return a;
        }

Yes it’s simple but I was just trying to persuade it to work… to no avail. I think it might be some sort of font issue?

Thanks!

You might consider looking into Axiis. It is a flex data visualization framework, and has some awesome example charts. The main deal though is you have full control over EVERTHING! Probably overkill for what you are doing, but it really is awesome.
