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
datanumber[][]图表数据数组
type'bar'|'line'|'pie''line'图表类型
widthstring'100%'图表宽度
heightstring'40px'图表高度
colorstring'#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

  1. 虚拟滚动:使用el-table-v2代替el-table处理大数据集
  2. 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()
  }
}
