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[3],
drilldown: {
name: 'Safari versions',
categories: ['Safari 5.0', 'Safari 4.0', 'Safari Win 5.0', 'Safari 4.1', 'Safari/Maxthon',
'Safari 3.1', 'Safari 4.1'],
data: [4.55, 1.42, 0.23, 0.21, 0.20, 0.19, 0.14],
color: colors[3]
}
}, {
y: 2.14,
color: colors[4],
drilldown: {
name: 'Opera versions',
categories: ['Opera 9.x', 'Opera 10.x', 'Opera 11.x'],
data: [ 0.12, 0.37, 1.65],
color: colors[4]
}
}];
function setChart(options) {
chart.series[0].remove(false);
chart.addSeries({
type: options.type,
name: options.name,
data: options.data,
color: options.color || 'white'
}, false);
chart.xAxis[0].setCategories(options.categories, false);
chart.redraw();
}
chart = new Highcharts.Chart({

dataLabels: {

formatter: function() {
return this.y +'%';
}
}
}
},
tooltip: {
formatter: function() {
var point = this.point,
s = this.x +':<b>'+ this.y +'% market share</b><br/>';
if (point.drilldown) {
s += 'Click to view '+ point.category +' versions';
} else {
s += 'Click to return to browser brands';
}
return s;
}
},

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