Question

Highcharts, Can you change the chart type for drilldowns?

I would like to present a standard "column" chart initially and then drilldown to a "bar" chart, I have tried everything I could think of....

I assumed it would be set in the drilldown code, but doesnt seem to work this way. As in...

drilldown: {
    type: 'pie',
    name: 'Chart1',
    categories ['1','2','3','4','5','6','7','8','9','10','11','12','13','14','15','16','17','18','19','20','21','22','23','24','25','26','27','28'],
    data: [1,2,3,4,5,6,7,8,9,10,1,2,3,4,5,6,7,8,9,10,1,2,3,4,5,6,7,8],
    color: colors[0]
}

I don't know what have you tried, but you can do it.
Take a look my example.

$(function () {
    var chart;
    $(document).ready(function() {

        var colors = Highcharts.getOptions().colors,
            categories = ['MSIE', 'Firefox', 'Chrome', 'Safari', 'Opera'],
            name = 'Browser brands',
            data = [{
                    y: 55.11,
                    color: colors[0],
                    drilldown: {
                        name: 'MSIE versions',
                        categories: ['MSIE 6.0', 'MSIE 7.0', 'MSIE 8.0', 'MSIE 9.0'],
                        data: [10.85, 7.35, 33.06, 2.81],
                        color: colors[0]
                    }
                }, {
                    y: 21.63,
                    color: colors[1],
                    drilldown: {
                        name: 'Firefox versions',
                        categories: ['Firefox 2.0', 'Firefox 3.0', 'Firefox 3.5', 'Firefox 3.6', 'Firefox 4.0'],
                        data: [0.20, 0.83, 1.58, 13.12, 5.43],
                        color: colors[1]
                    }
                }, {
                    y: 11.94,
                    color: colors[2],
                    drilldown: {
                        name: 'Chrome versions',
                        categories: ['Chrome 5.0', 'Chrome 6.0', 'Chrome 7.0', 'Chrome 8.0', 'Chrome 9.0',
                            'Chrome 10.0', 'Chrome 11.0', 'Chrome 12.0'],
                        data: [0.12, 0.19, 0.12, 0.36, 0.32, 9.91, 0.50, 0.22],
                        color: colors[2]
                    }
                }, {
                    y: 7.15,
                    color: colors[3],
                    drilldown: {
                        name: 'Safari versions',
                        categories: ['Safari 5.0', 'Safari 4.0', 'Safari Win 5.0', 'Safari 4.1', 'Safari/Maxthon',

                    }
                }, {
                    y: 2.14,
                    color: colors[4],
                    drilldown: {

                        color: colors[4]
                    }
                }];

        function setChart(options) {
            chart.series[0].remove(false);
            chart.addSeries({
                type: options.type,
                name: options.name,
                data: options.data,

            }, false);
            chart.xAxis[0].setCategories(options.categories, false);
            chart.redraw();
        }

        chart = new Highcharts.Chart({
            chart: {

});

Make sure you don't have a type defined for all your series. Reference

Answer 2

Well, I think it's enought if you define each serie's type

$(function () {
// Create the chart
Highcharts.chart('container', {
    title: {
        text: 'Browser market shares. January, 2015 to May, 2015'
    },
    subtitle: {
        text: 'Click the columns to view versions. Source: <a href="http://netmarketshare.com">netmarketshare.com</a>.'
    },
    xAxis: {
        type: 'category'
    },
    yAxis: {
        title: {
            text: 'Total percent market share'
        }

    },
    legend: {
        enabled: false
    },
    plotOptions: {
        series: {
            borderWidth: 0,
            dataLabels: {
                enabled: true,
                format: '{point.y:.1f}%'
            }
        }
    },

    tooltip: {
        headerFormat: '<span style="font-size:11px">{series.name}</span><br>',
        pointFormat: '<span style="color:{point.color}">{point.name}</span>: <b>{point.y:.2f}%</b> of total<br/>'
    },

    series: [{
        name: 'Brands',
        type: 'column',
        colorByPoint: true,
        data: [{
            name: 'Microsoft Internet Explorer',
            y: 56.33,
            drilldown: 'Microsoft Internet Explorer'
        }, {
            name: 'Chrome',
            y: 24.03,
            drilldown: 'Chrome'
        }, {
            name: 'Firefox',
            y: 10.38,
            drilldown: 'Firefox'
        }, {
            name: 'Safari',
            y: 4.77,
            drilldown: 'Safari'
        }, {
            name: 'Opera',
            y: 0.91,
            drilldown: 'Opera'
        }, {
            name: 'Proprietary or Undetectable',
            y: 0.2,
            drilldown: null
        }]
    }],
    drilldown: {
        series: [{
            type: 'line',
                name: 'Microsoft Internet Explorer',
            id: 'Microsoft Internet Explorer',
            data: //your drill data
        }, {

            id: 'Firefox',
            data: //your drill data
        }, {
            name: 'Safari',
            id: 'Safari',

            name: 'Opera',
            id: 'Opera',
            data: //your drill data
        }]
    }
});
