   yData is usually a string by default. No matter whether I set the type of the y axis to value or category, the first data is missing.
   
   
   echarts.registerTransform(ecStat.transform.regression);
   option = {
     dataset: [
       {
         source: [
           ['aa', '4862'],
           ['bb', '5294'],
           ['vv', '5934'],
           ['ff', '7171'],
           ['dd', '8964'],
         ]
       },
     ],
     title: {
       text: '1981 - 1998 gross domestic product GDP (trillion yuan)',
       subtext: 'By ecStat.regression',
       sublink: 'https://github.com/ecomfe/echarts-stat',
       left: 'center'
     },
     tooltip: {
       trigger: 'axis',
       axisPointer: {
         type: 'cross'
       }
     },
     xAxis: {
       type:'category',
       splitLine: {
         lineStyle: {
           type: 'dashed'
         }
       }
     },
     yAxis: {
       type:'value',
       splitLine: {
         lineStyle: {
           type: 'dashed'
         }
       }
     },
     series: [
       {
         name: 'scatter',
         type: 'scatter',
         datasetIndex: 0
       },
     ]
   };
