   你們範例中
   splitData()
   有誤
   錯誤:
       volumes.push([i, rawData[i][4], rawData[i][0] > rawData[i][1] ? 1 : -1]);
   
   應改為:
     
   if(i == 0)
        volumes.push([i, rawData[i][4], 0]);
   else if( rawData[i-1][1] < rawData[i][1] )
        volumes.push([i, rawData[i][4], 1]);
   else if( rawData[i-1][1] == rawData[i][1] )
        volumes.push([i, rawData[i][4], 0]);
   else
        volumes.push([i, rawData[i][4], -1]);
   
   visualMap中加入:
   
   {
     value: 0,
     color: flatColor
   },
   
   並定義
   const flatColor = '#5B5B5B';
   
   以上
