Flex 4 - Axis Title Bug

Question

When the verticalAxisTilteAlignment is 'vertical', the title will 'move' down and left off of the chart each time new line series are created.  The problem code is in ChartLabel:
            var p:AxisRenderer = AxisRenderer(parent);
            if (p.getStyle('verticalAxisTitleAlignment') == 'vertical')
                _label.rotation = 180;
                _label.y = _label.y + _label.height;
                _label.x = _label.x + _label.width;
After the first time through, the x and y are added to continuously causing the title to 'move' off the chart.  My (admittedly hackish) work-around is a TitleRenderer that extends ChartLabel with an overridden 'updateDisplayList' like so:
getChildAt(0).x = 0;
getChildAt(0).y = 0;
super.updateDisplayList(unscaledWidth, unscaledHeight);

Answer 1

I'm running into the same problem. Any chance you can show your code showing the TitleRenderer that extends ChartLabel, as well as how it's called? I've never done something like that before in Flex.
UPDATE:
I found a nice tutorial here:

The workaround, thanks to vsimons (really -- thank you!!!):
package path.to.this.file
          import flash.display.*;
          import flash.geom.Matrix;
          import mx.charts.*;
          import mx.charts.chartClasses.ChartLabel;
          public class MyTitleRenderer extends ChartLabel {
                    public functionMyTitleRenderer() {
  super();
                    override protected function updateDisplayList(w:Number, h:Number):void { 
                              getChildAt(0).x = 0;
                              getChildAt(0).y = 0;
                              super.updateDisplayList(unscaledWidth, unscaledHeight);
