html 复制代码 
<template>
  <div class="dashboard-container">
    <!-- 顶部标题和全局筛选 -->
    <DashboardHeader />
    <FilterRow />
    
    <!-- 主要图表区域 -->
    <main class="dashboard-main">
      <!-- 全宽性能趋势图 -->
      <div class="full-width-chart">
        <PerformanceTrendChart />
      </div>
      
      <!-- 左右布局：雷达图+直方图 -->
      <div class="chart-row">
        <div class="chart-half">
          <RadarChart />
        </div>
        <div class="chart-half">
          <HistogramChart />
        </div>
      </div>
      
      <!-- 左右布局：热力图+散点图 -->
      <div class="chart-row">
        <div class="chart-half">
          <HeatmapChart />
        </div>
        <div class="chart-half">
          <ScatterChart />
        </div>
      </div>
      
      <!-- 测试任务表格 -->
      <div class="full-width-table">
        <TestTaskTable />
      </div>
    </main>
  </div>
</template>

<style scoped>
.dashboard-container {
  display: flex;
  flex-direction: column;
  min-height: 100vh;
  padding: 20px;
  gap: 24px;
}

.dashboard-main {
  display: flex;
  flex-direction: column;
  gap: 24px;
  flex: 1;
}

.chart-row {
  display: grid;
  grid-template-columns: repeat(auto-fit, minmax(500px, 1fr));
  gap: 24px;
}

.full-width-chart,
.full-width-table {
  width: 100%;
}

/* 响应式调整 */
@media (max-width: 1200px) {
  .chart-row {
    grid-template-columns: 1fr;
  }
}

@media (max-width: 768px) {
  .dashboard-container {
    padding: 12px;
    gap: 16px;
  }
  
  .dashboard-main {
    gap: 16px;
  }
}
</style>

2.2 StatCard统计卡片组件开发

统计卡片用于展示关键指标，需要支持动态数据更新和状态指示。

vue 复制代码 
<script setup lang="ts">
import { computed } from 'vue'

interface StatCardProps {
  title: string
  value: number | string
  unit?: string
  change?: number  // 百分比变化
  trend?: 'up' | 'down' | 'neutral'
  loading?: boolean
}

const props = defineProps<StatCardProps>()

const trendColor = computed(() => {
  switch (props.trend) {
    case 'up': return '#52c41a'
    case 'down': return '#f5222d'
    default: return '#8c8c8c'
  }
})

const formattedValue = computed(() => {
  if (typeof props.value === 'number') {
    return props.value.toLocaleString()
  }
  return props.value
})
</script>

<template>
  <div class="stat-card" :class="{ 'stat-card-loading': loading }">
    <div class="stat-header">
      <span class="stat-title">{{ title }}</span>
      <span 
        v-if="change !== undefined" 
        class="stat-change"
        :style="{ color: trendColor }"
      >
        {{ trend === 'up' ? '↑' : '↓' }} {{ Math.abs(change) }}%
      </span>
    </div>
    
    <div class="stat-content">
      <span class="stat-value">{{ formattedValue }}</span>
      <span v-if="unit" class="stat-unit">{{ unit }}</span>
    </div>
    
    <!-- 加载状态 -->
    <div v-if="loading" class="stat-skeleton">
      <div class="skeleton-line"></div>
    </div>
  </div>
</template>

<style scoped>
.stat-card {
  background: white;
  border-radius: 8px;
  padding: 20px;
  box-shadow: 0 2px 8px rgba(0, 0, 0, 0.08);
  position: relative;
  transition: all 0.3s ease;
}

.stat-card:hover {
  box-shadow: 0 4px 12px rgba(0, 0, 0, 0.12);
}

.stat-header {
  display: flex;
  justify-content: space-between;
  align-items: center;
  margin-bottom: 12px;
}

.stat-title {
  font-size: 14px;
  color: #666;
  font-weight: 500;
}

.stat-change {
  font-size: 12px;
  font-weight: 500;
}

.stat-content {
  display: flex;
  align-items: baseline;
  gap: 4px;
}

.stat-value {
  font-size: 28px;
  font-weight: 600;
  color: #1f1f1f;
  line-height: 1.2;
}

.stat-unit {
  font-size: 14px;
  color: #8c8c8c;
  margin-left: 4px;
}

/* 加载状态 */
.stat-skeleton {
  position: absolute;
  top: 0;
  left: 0;
  right: 0;
  bottom: 0;
  background: rgba(255, 255, 255, 0.8);
  display: flex;
  align-items: center;
  justify-content: center;
}

.skeleton-line {
  width: 60%;
  height: 24px;
  background: linear-gradient(90deg, #f0f0f0 25%, #e0e0e0 50%, #f0f0f0 75%);
  background-size: 200% 100%;
  animation: loading 1.5s infinite;
  border-radius: 4px;
}

@keyframes loading {
  0% { background-position: 200% 0; }
  100% { background-position: -200% 0; }
}
</style>

2.3 筛选条件面板实现

筛选面板支持日期范围、模型类型、测试状态和阈值等多种筛选条件。

vue 复制代码 
<script setup lang="ts">
import { ref, watch } from 'vue'
import { ElDatePicker, ElSelect, ElInput } from 'element-plus'
import type { FilterParams } from '@/types/dashboard'

// 默认筛选条件
const defaultFilters: FilterParams = {
  dateRange: [new Date(Date.now() - 7 * 86400000), new Date()],
  modelTypes: [],
  status: 'all',
  minAccuracy: 0.8,
  maxResponseTime: 1000
}

const filters = ref<FilterParams>({ ...defaultFilters })

// 模型类型选项
const modelTypeOptions = [
  { label: '图像分类', value: 'classification' },
  { label: '目标检测', value: 'detection' },
  { label: '自然语言处理', value: 'nlp' },
  { label: '语音识别', value: 'speech' }
]

// 状态选项
const statusOptions = [
  { label: '全部', value: 'all' },
  { label: '进行中', value: 'running' },
  { label: '已完成', value: 'completed' },
  { label: '失败', value: 'failed' },
  { label: '排队中', value: 'pending' }
]

const emit = defineEmits<{
  'filter-change': [FilterParams]
}>()

// 监听筛选条件变化
watch(
  () => filters.value,
  (newFilters) => {
    emit('filter-change', newFilters)
  },
  { deep: true, immediate: true }
)

// 重置筛选条件
const resetFilters = () => {
  filters.value = { ...defaultFilters }
}
</script>

<template>
  <div class="filter-panel">
    <div class="filter-group">
      <label class="filter-label">时间范围</label>
      <ElDatePicker

3. 图表区域集成与联动

3.1 性能趋势图实现

性能趋势图展示AI模型各项指标随时间的变化趋势，支持多指标对比。

vue 复制代码 
<script setup lang="ts">
import { ref, onMounted, onUnmounted, watch } from 'vue'
import * as echarts from 'echarts'
import type { EChartsType } from 'echarts'

interface PerformanceData {
  timestamp: string[]
  accuracy: number[]
  recall: number[]
  f1Score: number[]
  responseTime: number[]
}

const props = defineProps<{
  data: PerformanceData
  loading?: boolean
}>()

const chartRef = ref<HTMLDivElement>()
let chartInstance: EChartsType | null = null

// 初始化图表
const initChart = () => {
  if (!chartRef.value) return
  
  chartInstance = echarts.init(chartRef.value)
  
  const option = {
    tooltip: {
      trigger: 'axis',
      axisPointer: {
        type: 'cross',
        label: {
          backgroundColor: '#6a7985'
        }
      }
    },
    legend: {
      data: ['准确率', '召回率', 'F1分数', '响应时间'],
      top: 20
    },
    grid: {
      left: '3%',
      right: '4%',
      bottom: '3%',
      top: '80px',
      containLabel: true
    },
    xAxis: {
      type: 'category',
      boundaryGap: false,
      data: props.data.timestamp
    },
    yAxis: [
      {
        type: 'value',
        name: '指标值',
        min: 0,
        max: 1,
        axisLabel: {
          formatter: '{value}'
        }
      },
      {
        type: 'value',
        name: '响应时间(ms)',
        position: 'right',
        axisLabel: {
          formatter: '{value}'
        }
      }
    ],
    series: [
      {
        name: '准确率',
        type: 'line',
        smooth: true,
        data: props.data.accuracy,
        itemStyle: {
          color: '#5470c6'
        }
      },
      {
        name: '召回率',
        type: 'line',
        smooth: true,
        data: props.data.recall,
        itemStyle: {
          color: '#91cc75'
        }
      },
      {
        name: 'F1分数',
        type: 'line',
        smooth: true,
        data: props.data.f1Score,
        itemStyle: {
          color: '#fac858'
        }
      },
      {
        name: '响应时间',
        type: 'line',
        yAxisIndex: 1,
        smooth: true,
        data: props.data.responseTime,
        itemStyle: {
          color: '#ee6666'
        }
      }
    ]
  }

  chartInstance.setOption(option)
}

// 响应式调整
const handleResize = () => {
  if (chartInstance) {
    chartInstance.resize()
  }
}

onMounted(() => {
  initChart()
  window.addEventListener('resize', handleResize)
})

onUnmounted(() => {
  if (chartInstance) {
    chartInstance.dispose()
    chartInstance = null
  }
  window.removeEventListener('resize', handleResize)
})

// 监听数据变化
watch(() => props.data, () => {
  if (chartInstance) {
    const option = chartInstance.getOption()
    option.xAxis[0].data = props.data.timestamp
    option.series[0].data = props.data.accuracy
    option.series[1].data = props.data.recall
    option.series[2].data = props.data.f1Score
    option.series[3].data = props.data.responseTime
    chartInstance.setOption(option)
  }
}, { deep: true })
</script>

<template>
  <div class="chart-container">
    <div v-if="loading" class="chart-loading">
      <div class="loading-spinner"></div>
      <span>图表加载中...</span>
    </div>
    <div ref="chartRef" class="chart" :style="{ height: '400px' }"></div>
  </div>
</template>

3.4 图表配置联动与交互

图表联动可以让用户在多个图表间进行交互分析，ECharts提供了两种主要实现方式：

typescript 复制代码 
import * as echarts from 'echarts'

// 方法1：使用connect方法实现多图联动
export const connectCharts = (chartInstances: echarts.ECharts[]) => {
  // 将所有图表实例连接起来
  echarts.connect(chartInstances)
  
  // 或者通过group属性连接
  chartInstances.forEach(instance => {
    instance.group = 'dashboard-group'
  })
  echarts.connect('dashboard-group')
}

// 方法2：基于事件监听的自定义联动
export const setupChartInteraction = (
  sourceChart: echarts.ECharts,
  targetCharts: echarts.ECharts[]
) => {
  // 监听源图表的点击事件
  sourceChart.on('click', (params) => {
    const { dataIndex, seriesIndex } = params
    
    // 更新目标图表
    targetCharts.forEach(chart => {
      const option = chart.getOption()
      
      // 高亮显示相关数据
      option.series.forEach((series: any, idx: number) => {
        if (series.data) {
          series.data.forEach((item: any, itemIndex: number) => {
            item.itemStyle = itemIndex === dataIndex 
              ? { borderColor: '#ff4d4f', borderWidth: 2 }
              : null
          })
        }
      })
      
      chart.setOption(option, true)
    })
  })
  
  // 监听图例选择变化
  sourceChart.on('legendselectchanged', (params) => {
    const { selected } = params
    
    targetCharts.forEach(chart => {
      chart.dispatchAction({
        type: 'legendSelect',
        name: Object.keys(selected)[0]
      })
    })
  })
}

4. 测试任务管理表格

4.1 分页表格组件封装

vue 复制代码 
<script setup lang="ts">
import { ref, computed, watch } from 'vue'
import { ElTable, ElTableColumn, ElPagination } from 'element-plus'
import type { TestTask } from '@/types/dashboard'

interface Props {
  data: TestTask[]
  loading?: boolean
  pageSize?: number
}

const props = withDefaults(defineProps<Props>(), {
  pageSize: 10,
  loading: false
})

const currentPage = ref(1)
const sortConfig = ref<{ prop: string; order: 'ascending' | 'descending' }>()

// 分页数据计算
const paginatedData = computed(() => {
  const start = (currentPage.value - 1) * props.pageSize
  const end = start + props.pageSize
  return props.data.slice(start, end)
})

// 排序处理
const handleSortChange = ({ prop, order }: any) => {
  sortConfig.value = { prop, order }
}

// 表格列配置
const columns = [
  { prop: 'id', label: 'ID', width: '80' },
  { prop: 'name', label: '任务名称', minWidth: '200' },
  { prop: 'modelType', label: '模型类型', width: '120' },
  { prop: 'status', label: '状态', width: '100' },
  { prop: 'accuracy', label: '准确率', width: '100' },
  { prop: 'startTime', label: '开始时间', width: '180' },
  { prop: 'endTime', label: '结束时间', width: '180' },
  { prop: 'actions', label: '操作', width: '120' }
]

// 状态颜色映射
const statusColorMap = {
  running: 'primary',
  completed: 'success',
  failed: 'danger',
  pending: 'warning'
}
</script>

<template>
  <div class="task-table">
    <ElTable
      :data="paginatedData"
      :loading="loading"
      @sort-change="handleSortChange"
      stripe
      border
    >
      <ElTableColumn
        v-for="col in columns"
        :key="col.prop"
        :prop="col.prop"
        :label="col.label"
        :width="col.width"
        :min-width="col.minWidth"
        :sortable="col.prop !== 'actions'"
      >
        <template #default="scope" v-if="col.prop === 'status'">
          <ElTag :type="statusColorMap[scope.row.status]">
            {{ scope.row.status }}
          </ElTag>
        </template>
        
        <template #default="scope" v-else-if="col.prop === 'actions'">
          <ElButton size="small" @click="$emit('view-detail', scope.row)">
            详情
          </ElButton>
          <ElButton 
            size="small" 
            type="danger" 
            @click="$emit('delete-task', scope.row.id)"
          >
            删除
          </ElButton>
        </template>
