我现在实现了鼠标点击显示数据功能，
1现在需要改成鼠标滑动上去就显示数据
2每个柱子顶部最大值全部显示出来
3y轴能定义个单位，比如温度什么的
希望能找到一个类似于MouseIndicator的方法给我用，请各位大神指教啊

我正在学习。dojo目前国内用户应该不是太多。版本变化也太快，中文文档不多是它最大的问题。不过我觉得感觉这个框架很有前途。

看来csdn玩dojo的人不多啊，我的问题已经解决了。
chart.connectToPlot("default", "China",function(args){
switch(args.type){
case "onclick":
if(args.index == 1){
var shape = args.shape;
alert(args.v);
}
break;
case "onmouseover":
var shape = args.shape;
//$("#td1").innerHTML(chartData2[args.index]+" :"+chartData[args.index]);
//alert($("#input1")[0].value);
document.getElementById("test").innerHTML=chartData2[args.index]+" :"+chartData[args.index];
break;
case "onmouseout":
//TODO...
break;
default:
//TODO...
break;
}
});
