[flexcoders] Animating line series chart in actionscript

[jonbehr]

I'm creating chart series in AS, which is working fine - the chart and all 
series are rendered perfectly. However, the animation doesnt seem to work at 
all.

private function createChart():void {
        
  var mySeries:Array = new Array();
  var myInterpolate:SeriesInterpolate = new SeriesInterpolate();
  myInterpolate.duration = 1000;
                                                        
  for(var item:String in model.bank_summary_chart[0]) {
    if (item != 'date_trans') {                                 
      var myLineSeries:LineSeries = new LineSeries();
      myLineSeries.yField = item;
      myLineSeries.xField = 'date_trans';
      myLineSeries.displayName = item;
      myLineSeries.setStyle('form','curve');
      myLineSeries.setStyle('showDataEffect', myInterpolate); //This line 
doesnt work at all                                    
      mySeries.push(myLineSeries);
      }
    }
    myChart.invalidateSeriesStyles();
    myChart.series = mySeries;
    callLater(setDataProvider);
}                                       

private function setDataProvider():void {
    myChart.dataProvider = model.bank_summary_chart;
}

Am I missing something really obvious here? Thanks for any help that you can 
provide.
