I have a parent chart that I need to drill down to a child chart with multiple series. Here is a toy example of what I would like to do. (I know this does not work)
Notice I'm trying to pass in an array of ids to display in the child chart.
Does anybody know a way to do this? If someone from Highcharts reads this, can this be added as a feature?
$(function () {
// Create the chart
$('#container').highcharts({
chart: {
type: 'column'
},
title: {
text: 'Basic drilldown'
},
xAxis: {
type: 'category'
},
plotOptions: {
column : {
stacking : 'normal'
}
},
series: [{
name: 'Yearly Orders',
data: [{
name: 'Location 1',
y: 100,
drilldown: ['l1-wa', 'l1-wb']
}, {
name: 'Location 2',
y: 150,
drilldown: ['l2-wa', 'l2-wb']
}]
}],
drilldown: {
series: [{
name: 'Widget A',
type: 'line',
id: 'l1-wa',
data: [
{name: 'Qtr 1', y: 5},
{name: 'Qtr 2', y: 25},
{name: 'Qtr 3', y: 25},
{name: 'Qtr 4', y: 20}
]
},{
name: 'Widget B',
type: 'line',
id: 'l1-wb',
data: [
{name: 'Qtr 1', y: 10},
{name: 'Qtr 2', y: 5},
{name: 'Qtr 3', y: 5},
{name: 'Qtr 4', y: 5}
]
}, {
name: 'Widget A',
type: 'line',
id: 'l2-wa',
data: [
{name: 'Qtr 1', y: 25},
{name: 'Qtr 2', y: 5},
{name: 'Qtr 3', y: 5},
{name: 'Qtr 4', y: 15}
]
},{
name: 'Widget B',
type: 'line',
id: 'l2-wb',
data: [
{name: 'Qtr 1', y: 30},
{name: 'Qtr 2', y: 30},
{name: 'Qtr 3', y: 15},
{name: 'Qtr 4', y: 25}
]
}
]
}
})
});
Here is a JSFiddle of this drilling down to just one series http://jsfiddle.net/F7z3D/2/
EDIT - I extended Highcharts to give me some enhanced changes when drilling down. This is probably not the best code, but gets the point across. This allows for changing of the x and y axes, changing the subtitle, and multiple series.
