Description

Steps to reproduce:
1. Run attached sample, chart shows
2. Click remove
3. Click Add

Actual Results:
When chart is added back to stage with addElement, the chart series does not show

Expected Results:
Chart added back onto stage correctly.

Workaround (if any):
Override this function in a subclass of CartesianChart:

override mx_internal function removeElements(parent:UIComponent,hasMask:Boolean):void
{
var n:int = parent.numChildren;
var stopIndex:int = hasMask ? 1 : 0;
for (var i:int = n - 1;
i >= stopIndex;
i--)
{
var c:DisplayObject = parent.removeChildAt;
var g:IChartElement = (c as IChartElement);
if (g && !(g is Series))
g.dataTransform = null;
}
}
