当我通过覆盖updateDisplayList函数在Flex中自定义ColumnChart时,图例中的颜色不再显示。正如您将在下面的图片中看到的那样:

我错过了什么吗?
感谢。

如果你想查看源代码,这就是我所做的。
覆盖受保护的功能 的updateDisplayList(参数unscaledWidth:编号,unscaledHeight属性:编号):无效 { super.updateDisplayList(unscaledWidth,unscaledHeight);
var fill:IFill;
var state:String = "";
if (_data is ChartItem && _data.hasOwnProperty('fill'))
{
state = _data.currentState;
fill = _data.fill;
}
else
fill = GraphicsUtilities.fillFromStyle(getStyle('fill'));
var color:uint;
var adjustedRadius:Number = 0;
color = ColorUtil.adjustBrightness2(GraphicsUtilities.colorFromFill(fill),-20);
fill = new SolidColor(color);
adjustedRadius = getStyle('adjustedRadius');
if (!adjustedRadius)
adjustedRadius = 0;
var stroke:IStroke = getStyle("stroke");
var w:Number = stroke ? stroke.weight / 2 : 0;
var rc:Rectangle = new Rectangle(w - adjustedRadius, w - adjustedRadius, width - 2 * w + adjustedRadius * 2, height - 2 * w + adjustedRadius * 2);
var g:Graphics = graphics;
g.clear();
g.moveTo(rc.left,rc.top);
if (stroke)
stroke.apply(g);
if (fill)
fill.begin(g,rc);
g.lineTo(rc.right-5,rc.top);
g.lineTo(rc.right-5,rc.bottom);
g.lineTo(rc.left+5,rc.bottom);
g.lineTo(rc.left+5,rc.top);
if (fill)
fill.end(g);
}

您可以使用legendMarkerRenderer格式化图例标记。本文将向您展示如何走向最底: http://livedocs.adobe.com/flex/3/html/help.html?content=charts_formatting_13.html
您还可以通过创建自己的LegendItem来自定义您的LegendItem: http://livedocs.adobe.com/flex/3/langref/mx/charts/LegendItem.html
