   itemStyle.color配置了linear渐变颜色，如下：
   ```js
   ...
   color: {
             type: 'linear',
             x: 0,
             y: 0,
             x2: 0,
             y2: 1,
             colorStops: [
                 { offset: 0, color: 'rgba(156,107,211,0.5)' },
                 { offset: 0.2, color: 'rgba(156,107,211,0.3)' },
                 { offset: 1, color: 'rgba(156,107,211,0)' }
             ]
           }
   ...
   ```
   toolTip.formatter中获取的maker是错误的。对象直接转字符串，没有对对象类型，即渐变颜色做处理。获得到的marker如下：
   ```html
   <span style="display:inline-block;margin-right:5px;border-radius:10px;width:10px;height:10px;
   background-color:[object Object];"></span>
   ```
