How to make yAxis stackLabels under yAxis in Highcharts? - highcharts

Question

I am using Stacked and grouped column to display data, I want to show the yAxis stackLabels and let it below yAxis as the picture shown below:
below is my core code and I have created a jsfiddle to show the result:
$(function () {
$('#container').highcharts({
chart: {
type: 'column'
},
title: {
text: 'Total fruit consumtion, grouped by gender'
},
xAxis: {
categories: ['Apples', 'Oranges', 'Pears', 'Grapes', 'Bananas'],
offset:30
},
yAxis: {
allowDecimals: false,
//offset:10,
title: {
text: 'Number of fruits'
},
stackLabels: {
enabled: true,
verticalAlign: 'bottom',
//y:30, //it will won't display labels if y is greater than 0
style: {
fontWeight: 'bold',
color: 'gray'
},
formatter: function() {
return this.stack;
}
}
},
tooltip: {
formatter: function () {
return '<b>' + this.x + '</b><br/>' +
this.series.name + ': ' + this.y + '<br/>' +
'Stack: ' + this.series.options.stack;
}
},
plotOptions: {
column: {
stacking: 'normal'
}
},
series: [{
name: 'John',
data: [5, 3, 4, 7, 2],
stack: 'male'
}, {
name: 'Joe',
data: [3, 4, 4, 2, 5],
stack: 'male'
}, {
name: 'Jane',
data: [2, 5, 6, 2, 1],
stack: 'female'
}, {
name: 'Janet',
data: [3, 0, 4, 4, 3],
stack: 'female'
}]
});
});
I found that if I set the value of y greater than 0 it will not show the stacklabels.
Can anyone help me, thanks a lot!
stackLabels: {
enabled: true,
verticalAlign: 'bottom',
y:30, //it will won't display labels if y is greater than 0
style: {
fontWeight: 'bold',
color: 'gray'
},
formatter: function() {
return this.stack;
}
}

Answer 1

You can simply use CSS (see https://www.highcharts.com/docs/chart-design-and-style/style-by-css):
.highcharts-stack-labels text {
transform: translate(0, 20px);
}

By default It is as you say
I found that if I set the value of y greater than 0,it will not show the stacklabels
To have desired behavior, you have to do following things:
1>Add extra series with negative values in each stack.
series: [{
name: 'test',
data: [-1, -1, -1, -1, -1],
stack: 'male',
color: 'transparent', //transparent color
showInLegend: false, //hide legend
}, {
name: 'tests',
data: [-1, -1, -1, -1, -1],
stack: 'female',
color: 'transparent',
showInLegend: false,
}, {
name: 'John',
data: [5, 3, 4, 7, 2],
stack: 'male'
}, {
name: 'Joe',
data: [3, 4, 4, 2, 5],
stack: 'male'
}, {
name: 'Jane',
data: [2, 5, 6, 2, 1],
stack: 'female'
}, {
name: 'Janet',
data: [3, 0, 4, 4, 3],
stack: 'female'
}]
2> In stackLabel property of yAxis you have to hide positive value stack labels
formatter: function() {
if (this.isNegative) {
return this.stack;
}
}
3>yAxis values should start from 0 show hide negative values,
labels: {
formatter: function() {
console.log(this.value)
if (this.value > -1) {
return this.value
}
}
},
4>Similarly tooltip should not activate on negative values
tooltip: {
formatter: function() {
if (this.y > -1) {
return '<b>' + this.x + '</b><br/>' +
this.series.name + ': ' + this.y + '<br/>' +
'Stack: ' + this.series.options.stack;
} else {
return false;
}
}
},
Applying this output
$(function() {
$('#container').highcharts({
chart: {
type: 'column'
},
title: {
text: 'Total fruit consumtion, grouped by gender'
},
xAxis: {
categories: ['Apples', 'Oranges', 'Pears', 'Grapes', 'Bananas'],
//offset:30
},
yAxis: {
allowDecimals: false,
//offset:10,
labels: {
formatter: function() {
if (this.value > -1) {
return this.value
}
}
},
title: {
text: 'Number of fruits'
},
stackLabels: {
enabled: true,
verticalAlign: 'bottom',
y: 0,
style: {
fontWeight: 'bold',
color: 'gray'
},
formatter: function() {
if (this.isNegative) {
return this.stack;
}
}
}
},
tooltip: {
formatter: function() {
if (this.y > -1) {
return '<b>' + this.x + '</b><br/>' +
this.series.name + ': ' + this.y + '<br/>' +
'Stack: ' + this.series.options.stack;
} else {
return false;
}
}
},
plotOptions: {
column: {
stacking: 'normal'
}
},
series: [{
name: 'test',
data: [-1, -1, -1, -1, -1],
stack: 'male',
color: 'transparent',
showInLegend: false,
tooltip: {
pointFormat: ''
}
}, {
name: 'tests',
data: [-1, -1, -1, -1, -1],
stack: 'female',
color: 'transparent',
showInLegend: false,
tooltip: {
pointFormat: ''
}
}, {
name: 'John',
data: [5, 3, 4, 7, 2],
stack: 'male'
}, {
name: 'Joe',
data: [3, 4, 4, 2, 5],
stack: 'male'
}, {
name: 'Jane',
data: [2, 5, 6, 2, 1],
stack: 'female'
}, {
name: 'Janet',
data: [3, 0, 4, 4, 3],
stack: 'female'
}]
});
