考慮下面的代碼在（對不起，我無法把它放在的jsfiddle）：變化軸線顏色的graphael圖表
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js"></script>
<script src="raphael.js"></script>
<script src="g.raphael.js"></script>
<script src="g.bar.js"></script>
<script src="g.line-min.js"></script>
<body>
<div style="width:500px;height:150px" id="div"></div>
<script>
var r = Raphael("div",400,150),
fin = function() {
this.flag = r.popup(this.x, this.y, this.value || "0").insertBefore(this).attr([{fill: "#bbbbbb"}]);
},
fout = function() {
this.flag.animate({opacity: 0}, 300, function() {this.remove();});
},
txtattr = { font: "12px sans-serif" };
var rr=r.linechart(0, 0, 400, 125, [0,1,2,3,4],[250,200,350,100,300], {axis: '0 0 1 0',axisxstep:4,symbol:'circle',width:1}).hoverColumn(fin, fout);
rr.axis[0].attr([{fill: "#bbbbbb"}]);
</script>
</body>
我想改變從黑x軸線的顏色爲灰色。我該怎麼做？
