area stack不能接收series做为参数吗?

area stack不能识别config中的series参数啊啊. 官方示例: http://echarts.baidu.com/demo.html#area-stack

我把示例中的series拷贝到了config中, 不识别..

 <area-chart config="vm.ac_config" data="vm.ac_data"></area-chart>

 vm.ac_config = {
    title: '件数推移',
    subtitle: '',
    yAxis: { scale: true },
    debug: true,
    stack: true,
    series : [
      {
        name:'邮件营销',
        type:'line',
        stack: '总量',
        areaStyle: {normal: {}},
        data:[120, 132, 101, 134, 90, 230, 210]
      },
      {
        name:'联盟广告',
        type:'line',
        stack: '总量',
        areaStyle: {normal: {}},
        data:[220, 182, 191, 234, 290, 330, 310]
      },
