   **TITLE**
   
   [Bug] The trigger condition of the highlight event in echarts
   
   **BODY**
   
   ### Version
   
   5.4.4
   
   ### Link to Minimal Reproduction
   
   https://echarts.apache.org/examples/zh/editor.html?c=bar-background
   
   ### Steps to Reproduce
   
   Official example using https://echarts.apache.org/examples/zh/editor.html?c=bar-background
   
   ### Current Behavior
   
   My understanding is that when the mouse enters a graph (such as a histogram, pie chart), the inserted part will be highlighted, so should the highlight event be triggered at this time?
   The fact is that the histogram I need to configure as follows:
   `import * as echarts from 'echarts';
   
   var chartDom = document. getElementById('main');
   var myChart = echarts.init(chartDom);
   var option;
   
   option = {
     // tooltip: {
     // show: true,
     // trigger: 'axis'
     // },
     xAxis: {
       type: 'category',
       data: ['Mon', 'Tue', 'Wed', 'Thu', 'Fri', 'Sat', 'Sun'],
       axisPointer: {
         show: true,
         type: 'shadow'
       }
     },
     yAxis: {
       type: 'value'
     },
     series: [
       {
         data: [120, 200, 150, 80, 70, 110, 130],
         type: 'bar',
         showBackground: true,
         backgroundStyle: {
           color: 'rgba(180, 180, 180, 0.2)'
         }
       }
     ]
   };
   
   myChart.on('highlight', function (e) {
     console.log('highlight pull', e);
   });
   
   option && myChart.setOption(option);`
   The axisPointer must be configured to trigger the highlight event. How to trigger the pie chart and the map has not been tried.
   I don't know if it's a bug or it's designed like this, or I understand it wrong
   
   
   ### Expected Behavior
   
   No other configuration is required, when the mouse enters the element, the corresponding highlight event is triggered
   
   ### Environment
   
   ```markdown
   - OS: windows 11
   - Browser: any version of chrome
   - Framework: Vue2 or applet
   ```
   
   
   ### Any additional comments?
   
   Beginners, if there is something wrong, please forgive me!
