+
+~[700x300](${galleryViewPath}doc-example/bar-drilldown&edit=1&reset=1)
+
+Before `childGroupId` is introduced, developers actually can use `groupId` to
make drilldown and aggregation animation already, but with the limit on the
times that a continious drilldown or aggregation can happen, which is only one
time.
+
+`childGroupId`, together with `groupId`, help to form "parent-child"
relationships between data items of different options, such as:
+
+```text
+data: [ data: [ data: [
+ { { {
+ name: 'Animals', name: 'Dogs', name:
'Corgi',
+ value: 3, value: 3, value: 5,
+ groupId: 'things', groupId: 'animals', groupId:
'dogs'
+ childGroupId: 'animals' childGroupId: 'dogs' },
+ }, }, {
+ { { name:
'Bulldog',
+ name: 'Fruits', name: 'Cats', value: 6,
+ value: 3, value: 4, groupId:
'dogs'
+ groupId: 'things', groupId: 'animals', },
+ childGroupId: 'fruits' childGroupId: 'cats', {
+ }, }, name: 'Shiba
Inu',
+ { { value: 7,
+ name: 'Cars', name: 'Birds', groupId:
'dogs'
+ value: 2, value: 3, }
+ groupId: 'things', groupId: 'animals', ]
+ childGroupId: 'cars' childGroupId: 'birds'
+ } }
+] ]
+```
+
+The 3 groups of data above come from 3 options, and by specifying `groupId`
and `childGroupId` for the data items a relationship of
"parent-child-grandChild" is formed in the 3 options. In this way, after
`setOption` is called, Apache ECharts will try to find the "parent-child" or
"child-parent" relationship of the old option and the new one. If the
relationship exists, the matching data items will be applied to a drilldown
animation or an aggregation one.
+
+If a data item has no child data then there is no need to specify a
`childGroupId` at all.
+If you are using the [dataset](~dataset) component to represent data, you are
recommended to use `encode.itemChildGroupId` to specify the dimension that is
to be encoded as the child group ID.

+
+引入`childGroupId`后，不同`option`的数据项之间就能形成逻辑上的父子关系，例如：
+
+```text

+ value: 2, value: 3, }
+ groupId: 'things', groupId: 'animals', ]
+ childGroupId: 'cars' childGroupId: 'birds'
+ } }
+] ]
+```
+
+上面 3 组 data 分别来自 3 个 option
，通过`groupId`和`childGroupId`，它们之间存在了“父-子-孙”的关系。在`setOption`时，Apache ECharts
会尝试寻找前后`option`数据项间的父子关系，若存在父子关系，则会对相关数据项进行下钻或聚合动画的过渡。
