   ### Steps to Reproduce
   
     // 5000个数据点的柱状图
     const bigDataBarChartOption = {
       title: {
         text: '大数据量柱状图 (5000个数据点)',
         left: 'center'
       },
       tooltip: {
         trigger: 'axis',
         axisPointer: {
           type: 'shadow'
         }
       },
       legend: {
         data: ['数据序列A', '数据序列B', '数据序列C']
       },
       xAxis: {
         type: 'category',
         data: Array.from({ length: 5000 }, (_, i) => `Point${i + 1}`),
         axisTick: {
           alignWithLabel: true
         },
         axisLabel: {
           show: false // 隐藏x轴标签以提高性能
         }
       },
       yAxis: {
         type: 'value'
       },
       dataZoom: [
         {
           type: 'inside',
           start: 0,
           end: 10
         },
         {
           start: 0,
           end: 10
         }
       ],
       series: [
         {
           name: '数据序列A',
           type: 'bar',
           data: Array.from({ length: 5000 }, () => Math.floor(Math.random() * 
1000) + 100),
           itemStyle: {
             color: '#5470c6'
           },
           emphasis: {
             focus: 'series',
             blurScope: 'coordinateSystem'
           }
         },
         {
           name: '数据序列B',
           type: 'bar',
           data: Array.from({ length: 5000 }, () => Math.floor(Math.random() * 
800) + 200),
           itemStyle: {
             color: '#91cc75'
           },
           emphasis: {
             focus: 'series',
             blurScope: 'coordinateSystem'
           }
         },
         {
           name: '数据序列C',
           type: 'bar',
           data: Array.from({ length: 5000 }, () => Math.floor(Math.random() * 
600) + 300),
           itemStyle: {
             color: '#fac858'
           },
           emphasis: {
             focus: 'series',
             blurScope: 'coordinateSystem'
           }
         }
       ]
     };
