Drilldown for grouped column chart in highcharts

问题

I'm trying to make drilldown for a grouped column chart in highcharts. My chart is here:

$(function () {

    // Create the chart
    $('#container').highcharts({
        chart: {
            type: 'column'
        },
        title: {
            text: 'Basic drilldown'
        },
        xAxis: {
            type: 'category',
            categories: [
                          "2011-12",
                          "2012-13",
                          "2013-14",
                          "2014-15",
                          "2015-16"
                        ]
            
        },

        legend: {
            enabled: false
        },

        plotOptions: {
            series: {
                borderWidth: 0,
                dataLabels: {
                    enabled: true,
                }
            }
        },

        series: [
                  {
                    "name": "First",
                    "data": [

Grouped Column Chart

I want to have a drilldown for every column in the chart. But I don't understand how to do that ?

回答1:

This is a great question!

In your series data, what you'll need to is define a y value and an associated drilldown id for each data point, such as: { y: 40351.62, drilldown: 'test' }.

Then, you can set up items in the drilldown attribute for the expanded data.

The beauty of this method is that you can specify drilldowns for only the columns you want (say, for only one series).

Here's the code I modified for this example:

drilldown : {
    series: [{
        name: 'Test Drilldown',
        id: 'test',
        data: [
            [ 'data A', 24.13 ],
            [ 'data B', 17.2 ],
            [ 'data C', 8.11 ],
            [ 'data D', 5.33 ]
        ]
    }]
},
series: [
      {
        "name": "First",
        "data": [
          { y: 40351.62, drilldown: 'test' },
          51506.83,
          68566.23,
          80596.9228,
          94329.31
        ]
      },
      // ... other series
]

I hope this is helpful for you!
