# 分图统计

上一节我们展示了 sub aggs 在饼图上的效果。不过这多层 agg，其实用的是同一类数据。如果在聚合中，要加上一些完全不同纬度的数据，还是在单一的图片上继续累加就不是很直观了。比如说，还是上一节用到的 PHP 慢函数堆栈。我们可以根据机房做一下拆分。由于代码部署等主动变更都是有灰度部署的，一旦发现某机房有异常，就可以及时处理了。

同样还是新建 sub aggs，但是在开始，选择 split chart 而不是 split slice。

从 URL 里可以看到，分图的 aggs 是 `schema:split`，而饼图分片的 aggs 是 `schema:segment`：

```

# Agent Instructions: Querying This Documentation

If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter:

```
GET https://hezhiqiang.gitbook.io/elkstack/kibana/examples/terms-split.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
