title: Is it possible to stop my labels disappearing on my flex pie chart between segment selections whilst interpolating?
body: <p>I have a flex pie chart:</p>
  
  <pre><code>    &lt;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)"&gt;
          &lt;mx:series&gt;
              &lt;mx:PieSeries id="QPieSeries" labelField="Answer" field="Value" labelPosition="callout"
                            showDataEffect="QSeriesInterpolate" alpha="1"
                            reserveExplodeRadius="0.05"/&gt;
          &lt;/mx:series&gt;
      &lt;/mx:PieChart&gt;
  </code></pre>
  
  <p>where the <code>QSeriesInterpolate</code> is a simple interpolation given in the declaration: </p>
  
  <pre><code>&lt;fx:Declarations&gt;       
      &lt;mx:SeriesInterpolate id="QSeriesInterpolate" duration="500" /&gt;
  &lt;/fx:Declarations&gt;
  </code></pre>
  
  <p>and the item click event looks like:</p>
  
  <pre><code>protected function QPieChart_itemClickHandler(event:ChartItemEvent):void
          {
                  var ExAr:Array = [];
                  ExAr[event.hitData.chartItem.index] = 0.05;
                  QPieSeries.perWedgeExplodeRadius = ExAr;
          }
  </code></pre>
  
  <p>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??</p>
  
  <p>ALSO! Another thing: Is it obvious to anyone why my dataTipFunction doesnt work? It looks as follows:</p>
  
  <pre><code>            public function QdataTipFunction(hitData:HitData):String
          {
              var a:String = "abc"
              return a;
          }
  </code></pre>
  
  <p>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? </p>
  
  <p>Thanks!</p>
