关于echarts中极坐标系的问题

[没影响]

关键代码：
ChartOption:
"{polar: { center:['50%','45%'],},grid :{ top: 100},
tooltip:{ show: true,formatter:function (params) {var id = params.dataIndex; return '连续报警次数：'+['1','6','7','9',][id] + '次' + '<br>出现次数：' + [[0,5],[0,1],[0,1],[0,1],][id][1] + '次' },},
angleAxis: {type: 'category',data:['1','6','7','9',]},
radiusAxis: {},
series:[{
name: 'ESD连续报警监控',
type:'bar',
stack: 'a',
data:[[0,5],[0,1],[0,1],[0,1],].map(function (d) { return d[1] - d[0];}),coordinateSystem:'polar'},
]
}"
报错如下：
Uncaught Error: Bar only support cartesian2d coordinateSystem
