I want to implement drilldown for heatmap or heatstock of highcharts

Question

I am not able to add drilldown for heatmap or heatstock of highcharts. There are examples present for drilldown where only one data is required.

E.g:
enter code hereenter code here`data: [5, 7, 3]

But not for 2D or 3D data.

E.g:

1. data: [[1479220200000, 107.11],
        [1479306600000, 109.99],
        [1479393000000, 109.95]]

2. data: [[0, 0, 10], [0, 1, 19], [0, 2, 8], [0, 3, 24]]

Can anyone please check if this can be implemented or its a bug in highcharts.?

Answer 1

You can add drilldown functionality to heatmap in the same way as to other series types. Example:

series: [{
    data: [{
        x: 0,
        y: 0,
        value: 10,
        drilldown: 'animals'
    }, {
        x: 0,
        y: 0,
        value: 10
    }, {
        x: 0,
        y: 1,
        value: 19
    }, {
        x: 1,
        y: 0,
        value: 92
    }, {
        x: 1,
        y: 1,
        value: 58
    }],
    dataLabels: {
        enabled: true,
        color: '#000000'
    }
}],
drilldown: {
    series: [{
        id: 'animals',
        data: [
            [0, 9, 7],
            [1, 10, 4],
            [2, 6, 3]
        ]
    }]
}
