问题

HeatMap的y轴分类标签未显示在左侧外部，而是偏移至最后一个单元格内部。代码预览时显示正常，但实际渲染后出现异常（如图所示）。

异常效果

HeatMap异常效果

原因分析

错误使用StockChart构造器：HeatMap属于Highcharts标准图表类型，却用了为股票时序数据设计的StockChart构造器，两者布局逻辑不兼容，导致坐标轴空间计算异常。
边距设置为0：chart.margin = [0,0,0,0]完全移除了图表左侧边距，y轴标签没有足够空间显示在外部，被挤压到绘图区域内。
容器高度未明确：图表设置height: "100%"但父容器无明确高度，渲染时高度计算偏差进一步加剧标签偏移问题。

解决方案

1. 替换构造器为标准Chart

修改MainHeatMap.vue中的构造器类型，使用Highcharts通用的Chart构造器：

<highcharts
  :constructor-type="'chart'"
  class="hc"
  :options="chartOptions"
  ref="chart"
></highcharts>

2. 调整图表边距，预留标签空间

修改chart.margin，给左侧留出足够空间容纳y轴标签：

chart: {
  backgroundColor: "#fbfcf8",
  type: "heatmap",
  plotBorderWidth: 1,
  height: "100%",
  margin: [10, 10, 10, 80], // 左侧边距设为80，可根据标签长度调整
},

3. 明确父容器高度

给MainTab.vue中的HeatMap容器添加固定高度，避免图表高度计算异常：

<div style="width: 100%; height: 500px;" class="d-flex flex-column">
  <HeatMap id="heatMap" style="width: 100%; height: 100%" />
</div>

4. 可选：优化y轴标签位置

如果标签仍有偏移，可通过y轴配置调整标签对齐和位置：

yAxis: {
  categories: ["Jun 16, 2024", "Jun 23, 2024", "Jun 30, 2024", "Jul 7, 2024", "Jul 14, 2024"],
  reversed: false,
  labels: {
    align: 'right',
    x: -10, // 向左偏移标签位置
    style: {
      whiteSpace: 'nowrap'
    }
  }
},
