css - 未应用 Flex ColumnSeries CSS 填充

Question

我正在尝试使用 CSS 在 Flex (v4.6) ColumnChart 中设置系列的填充颜色。我目前正在使用 setStyle，因为我还设置了 alpha 值，但我知道这是相当耗费资源的，所以我正在考虑不设置 alpha，只使用 CSS 设置颜色。但是，我无法使用类似以下的 CSS 声明让它工作:

mx|ColumnSeries {
fills: #FFCC33, #FF0033, #FF3333, #FF6633, #FF9933;

如果我定义以下样式，它工作正常:

    <fx:Style>
        @namespace s "library://ns.adobe.com/flex/spark";
        @namespace mx "library://ns.adobe.com/flex/mx";

        .anotherColour { fill: #CCFFB3; }

        .andAnotherColour { fill: #BBFF99; }

    </fx:Style>

并应用如下:

                <mx:ColumnSeries 
                    xField="Month" 
                    yField="Profit" 
                    displayName="Profit"
                    styleName="anotherColour"
                    />
                <mx:ColumnSeries 
                    xField="Month" 
                    yField="Expenses" 
                    displayName="Expenses"
                    styleName="andAnotherColour"
                    />

有人可以帮忙吗？

谢谢。丹.

试试这个:

 mx|ColumnSeries {
                fills: [0xFFCC33,0xFF0033,0xFF3333,0xFF6633,0xFF9933];
            }
