Highcharts:Grouped and stacked legend - highcharts

Question

I currently have a legend like Joe and John. I am needing to have a legend on Male and Female as well. How to add male and female legend as well to this. kindly help me out.
This is the JSFiddle of the code which I have tried so far.
Have also created a runnable snippet below if it would be of any help.
Highcharts.chart('container', {
chart: {
type: 'column'
},
title: {
text: 'Total fruit consumtion, grouped by gender'
},
xAxis: {
categories: ['Apples', 'Oranges', 'Pears', 'Grapes', 'Bananas']
},
yAxis: {
allowDecimals: false,
min: 0,
title: {
text: 'Number of fruits'
}
},
tooltip: {
formatter: function() {
return '<b>' + this.x + '</b><br/>' +
this.series.name + ': ' + this.y + '<br/>' +
'Total: ' + this.point.stackTotal;
}
},
plotOptions: {
column: {
stacking: 'normal'
}
},
series: [{
name: 'John',
data: [5, 3, 4, 7, 2],
stack: 'male',
color: "#1f77ac",
id: 'John'
}, {
name: 'Joe',
data: [3, 4, 4, 2, 5],
stack: 'male',
color: "#098ebb",
id: 'Joe'
}, {
name: 'John',
data: [2, 5, 6, 2, 1],
stack: 'female',
linkedTo: 'John',
color: "#1f77ac"
}, {
name: 'Joe',
data: [3, 2, 4, 4, 3],
stack: 'female',
linkedTo: 'Joe',

Answer 1

You can add empty series with names: male and female. To handle the click event use legendItemClick function:
series: [..., {
name: 'male',
events: {
legendItemClick: function() {
// hide some series
}
}
}, {
name: 'female',
events: {
legendItemClick: function() {
// hide some series
}
}
}]
