使用统计图

在新建的 /source/charts/index.md 文件中添加以下内容

<!-- 文章发布时间统计图 -->  
<div id="posts-chart" data-start="2024-01" style="border-radius: 8px; height: 300px; padding: 10px;"></div>  
<!-- 文章标签统计图 -->  
<div id="tags-chart" data-length="10" style="border-radius: 8px; height: 300px; padding: 10px;"></div>  
<!-- 文章分类统计图 -->  
<div id="categories-chart" data-parent="true" style="border-radius: 8px; height: 300px; padding: 10px;"></div>

当然也可以在其他页面引入文章统计图，如果出现图表显示不全的现象可以修改 div 的 height 属性。。

  • posts-chart 的 data-start="2021-01" 属性表示文章发布时间统计图仅显示 2021-01 及以后的文章数据。
  • tags-chart 的 data-length="10" 属性表示仅显示排名前 10 的标签。
  • categories-chart 的 data-parent="true" 属性表示 有子分类 时以旭日图显示分类，其他 无子分类 或 设置为false 或 不设置该属性 或 设置为其他非true属性 情况都以饼状图显示分类。
