Problem fixed. Here is the code. It seems a little stupid but it
works. var colors value is same with the value in chart series
render, so we can get the same color.
<mx:Legend dataProvider="{countryList}" initialize="initLegend()"
direction="horizontal" markerHeight="5" markerWidth="5" width="100%"/>
function initLegend() {
var fill : SolidColor;
var stroke : Stroke = new Stroke(0x001100);
var label : String;
var keyItems = new Array();
var colors =
[0x550000,0x660000,0x770000,0x880000,0x990000,0xAA0000,0xBB0000,0xCC00
00,0xDD0000,0xEE0000,0xFF0000,
0x005500,0x006600,0x007700,0x008800,0x009900,0x00AA00,0x00BB00,0x00CC0
0,0x00DD00,0x00EE00,0x00FF00,
0x000055,0x000066,0x000077,0x000088,0x000099,0x0000AA,0x0000BB,0x0000C
C,0x0000DD,0x0000EE,0x0000FF];
for (var i = 0; i < csaRO1.getElements.result.length;
i++) {
fill = new SolidColor(colors[i]);
keyItems[i]={label:csaRO1.getElements.result
[i].name,fill:fill,stroke:stroke};
}
countryList = keyItems;
}
