   ### One-line summary [问题简述]
   用到柱状图,块状的,希望达到如下效果:
   1)鼠标左键点击柱状块,高亮显示被点击块
   2)鼠标右键点击取消高亮。
   我是按照echarts官网API加的监听事件,但是感觉没效果,可是console.log是有效果的。
       let that = this;
       // 点击高亮
       that.StackBarChart.on('click', (params) => {
         console.log('click params:', params);
         that.StackBarChart.dispatchAction({
           type: 'highlight',
           // 使用数据
           dataIndex: params.dataIndex,
           // name: params.name,
           seriesIndex: params.seriesIndex,
           // seriesName: params.seriesName,
         });
         if (that.props.onClick) {
           let dataFromClick = {
             value: params.value,
             xAxis: params.name,
             legendType: params.seriesName,
           };
           that.props.onClick(dataFromClick);
         }
       });
   
       // 右键取消高亮
       that.StackBarChart.on('contextmenu', (params) => {
         console.log('contextmenu params:', params);
         that.StackBarChart.dispatchAction({
           type: 'downplay',
           // 使用数据
           dataIndex: params.dataIndex,
           // name: params.name,
           seriesIndex: params.seriesIndex,
           // seriesName: params.seriesName,
         });
       });
