How to handle tags and hierarchies in ag-grid table data structure? - ag-grid

Question

I would like to use the pivot feature, but since my data has a lot of tags (1-level nested), I'm not sure how to make ag-grid parse this data and recognize it.
Here's the data for example:
[
{
"_id": "1",
"symbol": "sym1",
"open_date": "2019-04-23",
"_type": "t1",
"currency": "USD",
"quantity": 456,
"tags": [
{
"tag": "G_TAG1",
"group_name": "Group_1",
},
{
"tag": "G_TAG2",
"group_name": "Group_1",
}
],
},
{
"_id": "2",
"symbol": "sym2",
"open_date": "2029-01-11",
"_type": "t2",
"currency": "EUR",
"quantity": 312,
"tags": [
{
"tag": "G3_TAG-ABC",
"group_name": "Group_3",
},
{
"tag": "G2_TAG-DEF",
"group_name": "Group_2",
},
{
"tag": "G_TAG3",
"group_name": "Group_1",
}
],
},
{
"_id": "3",
"symbol": "sym3",
"open_date": "2010-12-01",
"_type": "t3",
"currency": "AUD",
"quantity": 123,
"tags": [
{
"tag": "G_TAG3",
"group_name": "Group_1",
}
],
}
]
In columnDefs, I defined tags column like this:
{field:'tags',
enablePivot: true,
children: [
{
headerName: "Tag", valueGetter: params => params.data.tags.map(x => x.tag),
enablePivot: true,
},
{
headerName: "Tag Group", valueGetter: params => params.data.tags.map(x => x.group_name),
enablePivot: true,
},
]
},
Each data point has a list of tags and each tag can belong to a group or not. So the top-most hierarchy is the tag group and below that are the individual tags.
Is there a way aggrid can recognize this or a way I can transform the data so visualize per-tag or per-group statistics? For example, can I view stats grouped by tag group > tag > symbol?
