项目初始化
# 克隆仓库
git clone https://gitcode.com/gh_mirrors/vu/vue-echarts
# 安装依赖
cd vue-echarts && npm install element-plus @element-plus/icons-vue
基础组件引入
// main.ts
import { createApp } from 'vue'
import ElementPlus from 'element-plus'
import 'element-plus/dist/index.css'
import { use, registerTheme } from 'echarts/core'
import { BarChart, LineChart, PieChart } from 'echarts/charts'

import App from './App.vue'
// 按需引入ECharts模块
use([BarChart, LineChart, PieChart, GridComponent, TooltipComponent])
createApp(App)
.use(ElementPlus)
.mount('#app')
迷你图表组件封装
核心组件设计
创建MiniChart.vue组件,封装迷你图表基础功能:
<template>
<div
class="mini-chart"
:style="{ width: width, height: height }"
ref="chartRef"
/>
</template>
<script setup lang="ts">
import { ref, onMounted, onBeforeUnmount, watch } from 'vue'
import { init as initECharts, EChartsType } from 'echarts/core'
import type { Option } from 'echarts'
const props = defineProps({
data: {
type: Array as PropType<number[]>,
required: true
},
type: {
type: String as PropType<'bar' | 'line' | 'pie'>,
default: 'line'
},
width: {
type: String,
default: '100%'
},
height: {
type: String,
default: '40px'
},
color: {
type: String,
default: '#409eff'
}
})
const chartRef = ref<HTMLDivElement>(null)
let chartInstance: EChartsType | null = null
// 图表初始化
const initChart = () => {
if (!chartRef.value) return
// 销毁已有实例
if (chartInstance) {
chartInstance.dispose()
}
// 创建新实例
chartInstance = initECharts(chartRef.value, null, {
renderer: 'canvas',
useDirtyRect: true // 启用脏矩形渲染优化
})
// 设置迷你图表通用配置
const baseOption: Option = {
grid: {
top: 0,
right: 0,
bottom: 0,
left: 0,
containLabel: true
},
tooltip: {
trigger: 'axis',
axisPointer: {
type: 'line'
},
padding: 5,
confine: true // 限制tooltip在图表内显示
},
series: []
}
// 根据类型设置具体配置
switch (props.type) {
case 'bar':
baseOption.xAxis = { show: false }
baseOption.yAxis = { show: false }
baseOption.series.push({
type: 'bar',
data: props.data,
itemStyle: { color: props.color },
barWidth: 4,
silent: true // 关闭交互以提升性能
})
break
case 'line':
baseOption.xAxis = { show: false }
baseOption.yAxis = { show: false }
baseOption.series.push({
type: 'line',
data: props.data,
lineStyle: { width: 2, color: props.color },
symbol: 'none',
silent: true
})
break
case 'pie':
baseOption.series.push({
type: 'pie',
data: props.data.map((value, index) => ({
value, name: `data${index}`
})),
radius: ['80%', '90%'],
itemStyle: {
color: props.color,
borderWidth: 0
},
silent: true
})
break
}
chartInstance.setOption(baseOption)
}
// 响应式处理
watch(
() => props.data,
() => chartInstance?.setOption({
series: chartInstance.getOption().series
})
)
onMounted(initChart)
onBeforeUnmount(() => {
chartInstance?.dispose()
})
</script>
<style scoped>
.mini-chart {
display: inline-block;
vertical-align: middle;
overflow: hidden;
}
</style>
组件API设计
| 属性 | 类型 | 默认值 | 说明 |
|---|---|---|---|
| data | number[] | [] | 图表数据数组 |
| type | 'bar'|'line'|'pie' | 'line' | 图表类型 |
| width | string | '100%' | 图表宽度 |
| height | string | '40px' | 图表高度 |
| color | string | '#409eff' | 图表主色调 |
表格集成实现
基础表格配置
使用Element Plus的el-table组件构建基础表格:
<template>
<el-table
:data="tableData"
border
stripe
style="width: 100%"
:cell-style="{ padding: '8px 5px' }"
>
<el-table-column prop="name" label="产品名称" width="180" />
<el-table-column prop="sales" label="销售额" width="120" />
<el-table-column prop="trend" label="销售趋势" width="200">
<template #default="scope">
<mini-chart
:data="scope.row.trend"
type="line"
height="40px"
/>
</template>
</el-table-column>
<el-table-column prop="distribution" label="渠道分布" width="120">
<template #default="scope">
<mini-chart
:data="scope.row.distribution"
type="pie"
width="40px"
height="40px"
/>
</template>
</el-table-column>
<el-table-column prop="growth" label="增长率" width="180">
<template #default="scope">
<mini-chart
:data="scope.row.growth"
type="bar"
:color="scope.row.growth[4] > 0 ? '#67c23a' : '#f56c6c'"
/>
</template>
</el-table-column>
</el-table>
</template>
数据结构设计
// 表格数据类型定义
interface ProductData {
name: string
sales: number
trend: number[] // 趋势数据,5个时间点
distribution: number[] // 分布数据,最多5个类别
growth: number[] // 增长率数据,5个时间点
}
// 模拟数据生成
const generateMockData = (count: number): ProductData[] => {
return Array.from({ length: count }).map((_, i) => ({
name: `产品${i + 1}`,
sales: Math.floor(Math.random() * 100000) + 10000,
trend: Array.from({ length: 5 }).map(() => Math.floor(Math.random() * 100)),
distribution: [
Math.floor(Math.random() * 40) + 30,
Math.floor(Math.random() * 30) + 20,
Math.floor(Math.random() * 20) + 10
],
growth: Array.from({ length: 5 }).map(() =>
Math.floor(Math.random() * 200) - 100 // -100到100之间的随机数
)
}))
}
// 在组件中使用
const tableData = ref<ProductData[]>(generateMockData(10))
渲染效果增强
添加条件格式化与交互效果:
<template>
<!-- 增长率单元格增强 -->
<el-table-column prop="growth" label="增长率" width="180">
<template #default="scope">
<div class="growth-cell">
<span
class="growth-text"
:class="scope.row.growth[4] > 0 ? 'positive' : 'negative'"
>
{{ scope.row.growth[4] > 0 ? '+' : '' }}{{ scope.row.growth[4] }}%
</span>
<mini-chart
:data="scope.row.growth"
type="bar"
:color="scope.row.growth[4] > 0 ? '#67c23a' : '#f56c6c'"
/>
</div>
</template>
</el-table-column>
</template>
<style scoped>
.growth-cell {
display: flex;
align-items: center;
gap: 8px;
}
.growth-text {
min-width: 40px;
text-align: right;
}
.positive {
color: #67c23a;
}
.negative {
color: #f56c6c;
}
</style>
高级功能实现
响应式与动态加载
实现表格滚动时的图表懒加载:
<template>
<el-table
v-infinite-scroll="loadMore"
infinite-scroll-disabled="loading"
infinite-scroll-distance="100"
>
<!-- 表格列定义 -->
</el-table>
</template>
<script setup lang="ts">
import { ref } from 'vue'
import type { ProductData } from './types'
const tableData = ref<ProductData[]>([])
const loading = ref(false)
const page = ref(1)
// 初始加载
const loadInitialData = () => {
loading.value = true
// 模拟API请求延迟
setTimeout(() => {
tableData.value = generateMockData(10)
loading.value = false
}, 500)
}
// 滚动加载更多
const loadMore = () => {
if (loading.value) return
loading.value = true
page.value++
setTimeout(() => {
tableData.value.push(...generateMockData(5))
loading.value = false
}, 800)
}
loadInitialData()
</script>
图表与表格联动
实现行展开时显示详细图表:
<template>
<el-table
:data="tableData"
@expand-change="handleExpandChange"
>
<!-- 其他列定义 -->
<el-table-column type="expand">
<template #default="scope">
<div class="expanded-chart-container">
<v-chart
v-if="expandedRow === scope.row.name"
:option="generateDetailedOption(scope.row)"
style="width: 100%; height: 300px;"
/>
</div>
</template>
</el-table-column>
</el-table>
</template>
<script setup lang="ts">
import VChart from '@/src/ECharts'
import { ref } from 'vue'
const expandedRow = ref('')
const handleExpandChange = (row: ProductData, expanded: boolean) => {
expandedRow.value = expanded ? row.name : ''
}
// 生成详细图表配置
const generateDetailedOption = (row: ProductData) => {
return {
tooltip: { trigger: 'axis' },
legend: { data: ['销售额', '增长率'] },
grid: { top: 30, right: 30, left: 0, bottom: 0 },
xAxis: { type: 'category', data: ['1月', '2月', '3月', '4月', '5月'] },
yAxis: [{ type: 'value', name: '销售额' }, { type: 'value', name: '增长率(%)' }],
series: [
{
name: '销售额',
type: 'bar',
data: row.trend.map(v => v * 1000)
},
{
name: '增长率',
type: 'line',
yAxisIndex: 1,
data: row.growth
}
]
}
}
</script>
性能优化策略
- 虚拟滚动:使用
el-table-v2代替el-table处理大数据集 - 图表复用:实现图表实例池管理
// chartPool.ts
import { EChartsType } from 'echarts'
const chartPool = new Map<string, EChartsType[]>()
// 获取图表实例
export const acquireChart = (type: string): EChartsType | null => {
if (!chartPool.has(type)) {
chartPool.set(type, [])
}
const pool = chartPool.get(type)!
return pool.pop() || null
}
// 释放图表实例
export const releaseChart = (type: string, instance: EChartsType) => {
if (!chartPool.has(type)) {
chartPool.set(type, [])
}
// 清空实例内容但保留DOM
instance.clear()
chartPool.get(type)!.push(instance)
// 限制池大小,防止内存溢出
if (chartPool.get(type)!.length > 20) {
chartPool.get(type)!.shift()?.dispose()
}
}
