   可以配合hideTip事件清空lastTipIndex
   ```javascript
       var lastTipIndex = null;
       chart .on('showTip', function(event) {
         lastTipIndex = event.dataIndex;
       });
       chart .on('hideTip',  function(event) {
         lastTipIndex = null;
       });
       chart .getZr().on('click', function() {
           if (dataIndex != null) {
             // 执行点击事件动作
           }
       });
   ```
