### 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'
}
}
]
};

### Current Behavior
