使用Kibana在同一条形图上显示两个字段

Question

我想做一个这样的图表：

所以我想在同一个条形图上显示两个字段“rest_of_the_world”和“china”。 Y轴应该是包含X值（计数）的文档的数量。

因此，例如，我有150份文件在“rest_of_the_world”字段中有“1996”，“15”文件在“中国”字段中有“1996”。

可以用Kibana做这样的图表吗？是否可以绘制两者之间的差异？

Answer 1

这是一个老问题，但我正在寻找一个教程或其他东西来绘制这种图表。这是你要做的：

-Go to [Visualize] menu, then click on the [ + ] button to add a [Vertical bar] chart
-Choose your index
-On the Metrics panel expand the [Y-Axis] options (witch selected type should be Count)
-Change the [Aggregation] to Sum
-In [Field] choose the index field/column representing the number of documents

-On the Buckets panel expand [X-Axis] options
-Put on [Aggregation] the field/colum representing the year 
 (or, if there are many records with date choose {Date histogram}, select the 
 field with that date and choose {Yearly} in the [Interval])

-Then click on the [Add sub-buckets] button on the bottom of Buckets panel
-On [Sub Aggregations] choose Terms
-On [Field] choose the field/column representing the place of document

就是这样！
