Extjs4.0.7在用chart绘制图标时无法在IE中显示

在使用chart绘制图表时可以在chorme和FireFox中 正常的显示 但是在IE9中却无法显示 只是显示出一个图表的标题

这个是在chorme中显示的效果



以下是在FireFox中显示的效果



以下是在IE9中显示的效果 (只显示出图表的标题 以及X轴的标题)



 一下是源代码

Ext.onReady(function(){
    var dataStore = new Ext.data.JsonStore({
        fields:['name','percentAge','xxoo'],
        data:[
            {name:'A',percentAge:3,xxoo:9},
            {name:'B',percentAge:3,xxoo:6},
            {name:'C',percentAge:2,xxoo:4},
            {name:'D',percentAge:2,xxoo:3}
        ]
    });
    Ext.create('Ext.panel.Panel',{
        title:'XXOO图',
        height:'600',
        width:'600',
        renderTo:Ext.getBody(),
        layout:'fit',
        animate:true,
        shadow: true,
        items:[{
                xtype:'chart',
                store:dataStore,
                legend:{
                    position:'right'
                },
                axes:[{
                        type:'Numeric',
                        fields:['percentAge','xxoo'],
                        title:'百分比',
                        position:'left',
                        minimum:0,
                        maximum:10
                    },
                    {
                        type:'Category',
                        position:'bottom',
                        fields:['name'],
                        title:'XXOO'
                    }],
                series:[{
                    type:'line',
                    xField:'name',
                    yField:'percentAge'
                },{
                    type:'line',
                    xField:'name',
                    yField:'xxoo'
                }]
            }]
    })
})

你看下IE9 是否可以正常显示。若是不能显示就是bug,若是可以显示的话,可以点击查看源码。
