Did you mean DrillDown to work with stacked column/bar chart or something else?

You can use the following example for Drilldown with stacked column chart:

https://www.koolreport.com/examples/reports/drilldown/drilldown/

Change the single series column chart to a multi-series stacked one and replace the following drill down command:

            saleDrillDown.next({year:params.selectedRow[0]});

to using your column name, row value, etc. You can show value structure of params with this to know how to get needed parameters:

            // saleDrillDown.next({year:params.selectedRow[0]});
            console.log("params:", params);

Here's an example of multi-column ColumnChart in DrillDown:

                    ColumnChart::create(array(
                        ...
                        "columns"=>array(
                            "year"=>array(...),
                            "sale_amount"=>array(...),
                            "sale_amount2"=>array(...),
                        ), 
                        "clientEvents"=>array(
                            "itemSelect"=>"function(params){
                                console.log('params: ', JSON.stringify(params, null, 2));
                            }",
                        ),

And here's the params when a column is clicked:

{
  "selectedRowIndex": 0,
  "selectedColumnIndex": 2,
  "selectedValue": 6500435.400000001,
  "selectedRow": [
    "2003",
    3250217.7000000007,
    6500435.400000001
  ],
  "columnName": "Sale Amount 2",
  ...
}

Based on this you can pass the column name, index, or value to the next chart/table in DrillDown.
