quick-sort opened a new issue #10578: 雷达图不支持数据集 encode方式
URL: https://github.com/apache/incubator-echarts/issues/10578
 
 
   ### Version
   4.2.1
   
   ### Steps to reproduce
   ```
   {
       backgroundColor: '#161627',
       title: {
           text: 'AQI - 雷达图',
           left: 'center',
           textStyle: {
               color: '#eee'
           }
       },
       dataset: {
         source: [
             ['date', 'AQI', 'PM25', 'PM10', 'CO', 'NO2', 'SO2'],
             [200, 100,100,100,100,100,100]
             ],
           sourceHeader: true
       },
       legend: {
           bottom: 5,
           data: ['北京', '上海', '广州'],
           itemGap: 20,
           textStyle: {
               color: '#fff',
               fontSize: 14
           },
           selectedMode: 'single'
       },
       // visualMap: {
       //     show: true,
       //     min: 0,
       //     max: 20,
       //     dimension: 6,
       //     inRange: {
       //         colorLightness: [0.5, 0.8]
       //     }
       // },
       radar: {
           indicator: [
               {name: 'AQI', max: 400},
               {name: 'PM25', max: 400},
               {name: 'PM10', max: 400},
               {name: 'CO', max: 400},
               {name: 'NO2', max: 400},
               {name: 'SO2', max: 400}
           ],
           shape: 'circle',
           splitNumber: 4,
           name: {
               textStyle: {
                   color: 'rgb(238, 197, 102)'
               }
           },
           splitLine: {
               lineStyle: {
                   color: [
                       'rgba(238, 197, 102, 0.1)', 'rgba(238, 197, 102, 0.2)',
                       'rgba(238, 197, 102, 0.4)', 'rgba(238, 197, 102, 0.6)',
                       'rgba(238, 197, 102, 0.8)', 'rgba(238, 197, 102, 1)'
                   ].reverse()
               }
           },
           splitArea: {
               show: false
           },
           axisLine: {
               lineStyle: {
                   color: 'rgba(238, 197, 102, 0.5)'
               }
           }
       },
       series: [
           {
               name: '北京',
               type: 'radar',
               encode: {
                   value: 'date'
               },
               symbol: 'none',
               itemStyle: {
                   normal: {
                       color: '#F9713C'
                   }
               },
               areaStyle: {
                   normal: {
                       opacity: 0.1
                   }
               }
           }
       ]
   }
   ```
   
   ### What is expected?
   encode.value =  ['AQI', 'PM25', 'PM10', 'CO', 'NO2', 'SO2']时正常画出雷达图
   
   ### What is actually happening?
   encode.value=['date']时才画出雷达图
