How to set Highcharts labels width to 50%

I have a Highcharts' bar chart with long labels.
I would like to allow them to grow up to 50% of the width of the container.
But no matter what I would do, they are not growing to this width.
Here is an example:
https://jsfiddle.net/agex7m0o/1/
Highcharts.chart('container', {
chart: {
type: 'bar'
},
title: {
text: 'Historic World Population by Region'
},
subtitle: {
text: 'Source: Wikipedia.org'
},
xAxis: {
categories: ['Africa Long Name Long Name Long Name Long Name Long Name', 'America', 'Asia', 'Europe', 'Oceania'],
title: {
text: null
},
labels: {
overflow: 'justify'
}
},
yAxis: {
min: 0,
title: {
text: 'Population (millions)',
align: 'high'
},
labels: {
overflow: 'justify'
}
},
tooltip: {
valueSuffix: ' millions'
},
plotOptions: {
bar: {
dataLabels: {
enabled: true
}
}
},
legend: {
layout: 'vertical',
align: 'right',
verticalAlign: 'top',
x: -40,
y: 80,
floating: true,
borderWidth: 1,
backgroundColor:
Highcharts.defaultOptions.legend.backgroundColor || '#FFFFFF',
shadow: true
},
credits: {
enabled: false
},
series: [{
name: 'Year 1800',
data: [107, 31, 635, 203, 2]
}, {
name: 'Year 1900',
data: [133, 156, 947, 408, 6]
}, {
name: 'Year 2000',
data: [814, 841, 3714, 727, 31]
}, {
name: 'Year 2016',
data: [1216, 1001, 4436, 738, 40]
}]
});
As you can see, the width of the left side (with the labels) is clearly narrower than the chart side. The labels are wrapping already, but the left side is not growing.
Do you have any idea ?

You can play with the margin parameter by adding in your chart options:
chart: {
type: 'bar',
margin: [50,10,50,400]
},
see exemple : here

In the below demo the chart yAxis width is set as 50% of the general chart container width. Is that a solution which you have been looking for?
Demo: https://jsfiddle.net/BlackLabel/z0vbcf5x/
events: {
render() {
let chart = this;
if (chartForRender) {
chartForRender = false;
chart.update({
chart: {
marginLeft: chart.chartWidth / 2
}
}, true, false, false)
}
chartForRender = true;
}
}

X-axis interval in Highcharts

I have this highchart graph displayed on my website. How can I set an interval for my x-axis? e.g. I want the fist value to be displayed and then skip the second and display the third.
Can this be done? Or do you always just HAVE to display all the data you're passing to the axis in an array?
My code: (timestamp is a JS array that contains my time. I can get that time in epoch format. act and temps are arrays for data to be plotted along y-axis)
$(function () {
$('#tempactgraph').highcharts({
chart: {
zoomType: 'xy'
},
title: {
text: 'Temperature & Activity Monitoring '
},
subtitle: {
text: 'Source: Cowlar Sensors'
},
xAxis: [{
categories: timestamp,
crosshair: true
}],
yAxis: [{ // Primary yAxis
labels: {
format: '{value}°C',
style: {
color: Highcharts.getOptions().colors[1]
}
},
title: {
text: 'Temperature',
style: {
color: Highcharts.getOptions().colors[1]
}
}
}, { // Secondary yAxis
title: {
text: 'Activity',
style: {
color: Highcharts.getOptions().colors[0]
}
},
labels: {
format: '{value} xx',
style: {
color: Highcharts.getOptions().colors[0]
}
},
opposite: true
}],
tooltip: {
shared: true
},
legend: {
layout: 'vertical',
align: 'left',
x: 120,
verticalAlign: 'top',
y: 100,
floating: true,
backgroundColor: (Highcharts.theme && Highcharts.theme.legendBackgroundColor) || '#FFFFFF'
},
series: [{
name: 'Activities',
type: 'spline',
connectNulls: 1,
yAxis: 1,
data: act,
tooltip: {
valueSuffix: ' xx'
}
}, {
name: 'Temperature',
type: 'spline',
connectNulls: 1,
data: temps,
tooltip: {
valueSuffix: '°C'
}
}]
});
});

You need to Add a tickInterval:2 to your x-axis decleration like so
xAxis: [{
categories: timestamp,
crosshair: true,
tickInterval: 2
}],

Highcharts not plotting series correctly on secondary axis

Hi I am using the Highcharts library to create a bar chart with a cumulative plot line as demonstrated in the jsFiddle below.
CHART DEMO
I am looking to have the cumulative series represented like the red line in the following image (with cumulative values plotted on the right-most axis):
SAMPLE OF DESIRED OUTPUT
As you can see the secondary Y Axis is flipped and is displaying the series index value rather than the actual cumuative values.
Here is the current code:
$('#container').highcharts({
chart: {
type: 'column'
},
title: {
text: 'Historic World Population by Region'
},
subtitle: {
text: 'Source: Wikipedia.org'
},
xAxis: [{
categories: ['Africa', 'America', 'Asia', 'Europe', 'Oceania'],
title: {
text: null,
}
},
{
opposite:true,
title: {
text: "Cumulative"
}
}],
yAxis: {
min: 0,
title: {
text: 'Population (millions)',
align: 'high'
}
},
tooltip: {
valueSuffix: ' millions'
},
plotOptions: {
bar: {
dataLabels: {
enabled: true
}
}
},
legend: {
layout: 'vertical',
align: 'right',
verticalAlign: 'top',
x: -40,
y: 100,
floating: true,
borderWidth: 1,
backgroundColor: ((Highcharts.theme && Highcharts.theme.legendBackgroundColor) || '#FFFFFF'),
shadow: true
},
credits: {
enabled: false
},
series: [{
name: 'Year 1900',
data: [133, 156, 947, 408, 6]
}, {
name: 'Year 2008',
data: [973, 914, 4054, 732, 34]
}, {
name: 'Cumulative',
xAxis:1,
type:"spline",
data: [34, 732, 914, 1973, 4054]
}
]
});
How can I correct this in order to plot the series as intended?
Thanks!

What you can do is after loading add a new series based on the sum of the 2 series added at creation:
events: {
load: function () {
var s1900 = this.series[0].data;
var s2008 = this.series[1].data;
var newData = [];
if (s1900.length == s2008.length) {
for (var i = 0; i < s1900.length; i++) {
newData.push(s1900[i].y + s2008[i].y);
}
}
this.addSeries({
name: 'Cumulative',
xAxis: 0,
type: "spline",
data: newData
});
}
}
I am not sure why you want this on the opposite xAxis or why your curve in the linked image you supplied is not really the cumulative unless that is not what you really want. See live demo.
Note you are going to have to handle cases where not all points have a value or if one category is not in both series, etc etc etc.
Revised answer.
Assuming you want to have the same categories on the alternate xAxis and do not want to share the same yAxis you can do:
...
xAxis: [{
categories: ['Africa', 'America', 'Asia', 'Europe', 'Oceania'],
title: {
text: null
}
}, {
categories: ['Africa', 'America', 'Asia', 'Europe', 'Oceania'],
opposite: true,
title: {
text: null
}
}],
yAxis: [{
min: 0,
endOnTick: false,
title: {
text: 'Population (millions)',
align: 'high'
}
}, {
min: 0,
opposite: true,
reversed: true,
endOnTick: true,
title: {
text: 'Cumulative Population (millions)',
align: 'high'
}
}],
...
This sets it up so that you have identical xAxis categories (other ways to do this). See new demo.

Remove space in bar charts in high charts for undefined values

I'm creating a bar chart using high charts. Here is a sample: http://jsfiddle.net/anishantha87/kfg5c/3/
$(function () {
$('#container').highcharts({
chart: {
type: 'bar'
},
title: {
text: 'Historic World Population by Region'
},
subtitle: {
text: 'Source: Wikipedia.org'
},
xAxis: {
categories: ['Europe', 'Oceania','France'],
title: {
text: null
}
},
yAxis: {
min: 0,
title: {
text: 'Population (millions)',
align: 'high'
},
labels: {
overflow: 'justify'
}
},
tooltip: {
valueSuffix: ' millions'
},
plotOptions: {
bar: {
dataLabels: {
enabled: true
}
},
},
legend: {
layout: 'vertical',
align: 'right',
verticalAlign: 'top',
x: -40,
y: 100,
floating: true,
borderWidth: 1,
backgroundColor: '#FFFFFF',
shadow: true
},
credits: {
enabled: false
},
series: [{
name: 'Year 1800',
data: [ 203, 200,200]
}, {
name: 'Year 1900',
data: [ 408, 60,null]
}, {
name: 'Year 2008',
data: [ 732, 34,null]
}]
});
});
In that I have null value for France. It displays the bar down below the France.(not vertically aligned with the Y axis name)
Any suggestions pls?
