你好，目前提供选中图形的方法有两种，一种是`select`方法，参见[select文档](https://echarts.apache.org/zh/option.html#series-bar.select)。
 
第二种是用on监听'click'事件，然后监测到click之后对option进行改变，参考[鼠标事件](https://echarts.apache.org/handbook/zh/concepts/event)。
   Hi, currently there are two ways to highlight the column. The first one is 
to use `select`, referring to 
[documentation](https://echarts.apache.org/zh/option.html#series-bar.select). 
The second one is to use 'on' to add listener for 'click' event, and alter 
`option` when 'click' is dispatched, referring to [mouse 
event](https://echarts.apache.org/handbook/zh/concepts/event).
   
   以下提供一种select的方案，可供参考

   ```
   option = {
     xAxis: {
       type: 'category',
       data: ['Mon', 'Tue', 'Wed', 'Thu', 'Fri', 'Sat', 'Sun']
     },
     yAxis: {
       type: 'value'
     },
     series: [
       {
         data: [120, {value: 200,name:'data'}, 150, 80, 70, 110, 130],
         type: 'bar',
         name: 'but',
         selectedMode: 'single',
         select: {
           itemStyle: {
             shadowBlur: 30,
             shadowColor: 'rgba(255,0,0,0.8)'
           }
         }
       }
     ],
     legend: {},
   
     tooltip: {
       trigger:'axis',
       axisPointer: {
         type: 'shadow',
         shadowStyle: {
           color: 'blue',
           opacity: 0.1
         }
       }
     }
   };
   ```
