当数值为负数时，areaStyle会出现在上方，如下图：

option = {
        
      xAxis: {
        
        type: 'category',
        boundaryGap: false,
        data: ['Mon', 'Tue', 'Wed', 'Thu', 'Fri', 'Sat', 'Sun']
      },
      yAxis: {
        
        type: 'value'
      },
      series: [
        {
        
          data: [-820, -932, 901, 934, -1290, 1330, 1320],
          type: 'line',
          areaStyle: {
        
          }
        }
      ]
    };

想areaStyle一直位于折线图下方，在 areaStyle 属性中增加属性： origin: ‘start’
