A metric visualization displays a single number for each aggregation you select:

为你选择的聚合显示一个单独的数字：

Count 计数

The count aggregation returns a raw count of the elements in the selected index pattern.

索引模式中，元素的原始计数。

Average 平均值

一个数值字段的平均值，从下拉菜单中选择一个字段。

Sum 综合

The sum aggregation returns the total sum of a numeric field. Select a field from the drop-down.

一个数值字段的总和。

Min 最小值

The min aggregation returns the minimum value of a numeric field. Select a field from the drop-down.

一个数值字段的最小值。

Max 最大值

The max aggregation returns the maximum value of a numeric field. Select a field from the drop-down.

一个数值字段的最大值。

Unique Count 单一计数

The cardinality aggregation returns the number of unique values in a field. Select a field from the drop-down.

去重数据值。

Standard Deviation 标准差

The extended stats aggregation returns the standard deviation of data in a numeric field. Select a field from the drop-down.

一个数值字段的标准差

Percentiles 百分比

The percentile aggregation divides the values in a numeric field into percentile bands that you specify. Select a field from the drop-down, then specify one or more ranges in the Percentiles fields. Click the Xto remove a percentile field. Click + Add to add a percentile field.

一个数值字段中，值的百分比分布。使用X来移除一个百分比框，使用+ Add 来添加百分比框。

Percentile Rank 百分比排名

The percentile ranks aggregation returns the percentile rankings for the values in the numeric field you specify. Select a numeric field from the drop-down, then specify one or more percentile rank values in the Values fields. Click the X to remove a values field. Click +Add to add a values field.

一个数值字段中，你指定值得百分比排名。

You can add an aggregation by clicking the + Add Aggregation button. You can click the Advanced link to display more customization options:

Viewing Detailed Information 查看详细信息

To display the raw data behind the visualization, click the bar at the bottom of the container. Tabs with detailed information about the raw data replace the visualization:

想要展现可视化背后的原始数据，可以点击容器底部的条。关于原始数据的详细信息标签将取代可视化。

Table. A representation of the underlying data, presented as a paginated data grid. You can sort the items in the table by clicking on the table headers at the top of each column.

表：对下划线数据的代表，以标页数据格的形式展现。你可以对表中数据线排序，通过点击每个柱顶的表头。

Request. The raw request used to query the server, presented in JSON format.

请求：原始请求被用于请求服务器，以JSON形式展现。

Response. The raw response from the server, presented in JSON format.

响应：来自服务器的原始应答，以JSON形式展现。

Statistics. A summary of the statistics related to the request and the response, presented as a data grid. The data grid includes the query duration, the request duration, the total number of records found on the server, and the index pattern used to make the query.

统计：关于请求和响应统计的摘要，以数据格的形式展现。数据格包括请求持续时间，响应持续时间，服务器创建的总数据记录，被用于请求的索引模式。

To export the raw data behind the visualization as a comma-separated-values (CSV) file, click on either theRaw or Formatted links at the bottom of any of the detailed information tabs. A raw export contains the data as it is stored in Elasticsearch. A formatted export contains the results of any applicable Kibana field formatters.

为了展现以CSV文件存在的可视化背后的原始数据，点击详细信息底部的Raw 或 Formatted 链接。一个原始输出包括保存在ES中的数据。一个格式化的输出包括Kibana格式化应用的结果。
