How to prevent an ApexCharts chart label from being slanted

I am working on my project with Django where I need to use Javascript and a chart library. I have two charts that I made with ApexCharts, but I don't know how to prevent the label text to being slant and overflow. I can't find anything about this problem in the documentation or I'm not enough familiar to find what I need. :)
var options07 = {
series: [{
name: 'SOHA',
data: [ {{i.szervkult07a}} ]
}, {
name: 'RITKÁN',
data: [ {{i.szervkult07b}} ]
}, {
name: 'IDŐNKÉNT',
data: [ {{i.szervkult07c}} ]
}, {
name: 'GYAKRAN',
data: [ {{i.szervkult07d}} ]
}, {
name: 'MINDIG',
data: [ {{i.szervkult07e}} ]
}],
chart: {
type: 'bar',
height: 350,
stacked: true,
stackType: '100%'
},
responsive: [{
breakpoint: 480,
options: {
legend: {
position: 'bottom',
offsetX: -10,
offsetY: 0
}
}
}],
xaxis: {
categories: ['A cég gondot fordít az ügyfelek igényeinek minél jobb megismerésére'
],
},
fill: {
opacity: 1
},
legend: {
position: 'right',
offsetX: 0,
offsetY: 50
},
};
var chart = new ApexCharts(document.querySelector("#chart_szk07"), options07);
chart.render();
var options07b = {
series: [{
name: 'SOHA',
data: [{{i.szervkult07a}}]
}, {
name: 'RITKÁN',
data: [{{i.szervkult07b}}]
}, {
name: 'IDŐNKÉNT',
data: [{{i.szervkult07c}}]
}, {
name: 'GYAKRAN',
data: [{{i.szervkult07d}}]
}, {
name: 'MINDIG',
data: [{{i.szervkult07e}}]
}],
chart: {
type: 'bar',
height: 350
},
plotOptions: {
bar: {
horizontal: false,
columnWidth: '55%',
endingShape: 'rounded'
},
},
dataLabels: {
enabled: false
},
stroke: {
show: true,
width: 2,
colors: ['transparent']
},
xaxis: {
categories: ['A cég gondot fordít az ügyfelek igényeinek minél jobb megismerésére'],
},
yaxis: {
title: {
text: 'fő'
}
},
fill: {
opacity: 1
},
tooltip: {
y: {
formatter: function (val) {
return val + " fő"
}
}
}
};
var chart = new ApexCharts(document.querySelector("#chart_szk07b"), options07b);
chart.render();

From the docs, You should be able to add rotate: 0 to the labels section of xaxis. I suggest trying to shorten those. I imagine a long label will not look as good as a shorter one.
xaxis: {
categories: ['A cég gondot fordít az ügyfelek igényeinek minél jobb megismerésére'],
labels: {
rotate: 0
}
}

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
link to the API: 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;
}
}

How to show xAxis categories up to the each chart in Bar-Highcharts library?

I want to show my categories on the top of each bar chart. like the image.
for this i set bar-chart option as below without any xAxis categories label.
options: {
title: null,
chart: {
type: 'bar'
},
colors: ['#9696b2', '#ff058d'],
xAxis: {
categories: ['Tokyo', 'Fukuoka', 'Hiroshima', 'Osaka', 'Nagoya'],
visible: false,
},
yAxis: {
visible: false,
},
tooltip: {
valueSuffix: ' '
},
plotOptions: {
bar: {
dataLabels: {
enabled: true
}
}
},
legend: {
enabled: false
},
credits: {
enabled: false
},
series: [{
name: 'Compliant',
data: [1300, 1121, 1700, 1121, 700]
}, {
name: 'Non-Compliant',
data: [60, 30, 50, 20, 0]
}]
}
how can i make this one with stacked horizontal bars?

You can align labels to left and position them by x and y properties:
xAxis: {
...,
lineWidth: 0,
labels: {
align: 'left',
x: 0,
y: -24
}
}

How to do a data overlap independently column in Highcharts

I would like to have something similar to the image below, but the columns representing the classes all stack together now. How do I separate them and allow them to load dynamically as well?
Also I need a legend that says green is band 1, yellow is band 2, orange is band 3 and red is band 4, how do i do that as well? My code is in the JS Fiddle page. I am not allowed to use jQuery, need to use pure JavaScript.
var options = {
chart: {
renderTo : 'container',
type: 'column'
},
title: {
text: 'Topic & Subtopic Mastery'
},
subtitle: {
text: 'Average Level-Stream Mastery vs Average Class Mastery'
},
xAxis: {
categories: topics
},
yAxis: {
min: 0,
max: 100,
title: {
text: 'Mastery'
}
},
legend: {
layout: 'vertical',
backgroundColor: '#FFFFFF',
align: 'left',
verticalAlign: 'top',
x: 100,
y: 70,
floating: true,
shadow: true
},
tooltip: {
shared: true,
valueSuffix: ' %'
},
plotOptions: {
column: {
grouping: false,
shadow: false
}
},
series: resultsData
};

I came up with a solution you are looking for with specifying x and y axis data for level and giving appropriate width to the point.
$(function() {
var chart;
$(document).ready(function() {
var i = 0;
Highcharts.getOptions().colors = Highcharts.map(Highcharts.getOptions().colors, function(color) {
if (i == 0) {
i++;
return Highcharts.Color(color)
.setOpacity(1)
.get('rgba');
} else {
i++;
return Highcharts.Color(color)
.setOpacity(0.5)
.get('rgba');
}
});
var colors = Highcharts.getOptions().colors;
chart = new Highcharts.Chart({
chart: {
renderTo: 'container',
type: 'column',
plotBackgroundColor: null,
plotBorderWidth: null,
plotShadow: false,
borderColor: null
},
title: {
text: 'Mailboxes over Quota'
},
subtitle: {
text: 'Mailbox Size in MB'
},
exporting: {
enabled: false
},
credits: {
enabled: false
},
xAxis: {
categories: ["Overall Topic", "Topic 1", "Topic 2"],
title: {
text: null
}
},
yAxis: {
min: 0,
title: {
text: 'Total',
align: 'high'
},
allowDecimals: false,
},
tooltip: {
formatter: function() {
return '' +
this.series.name + ': ' + Highcharts.numberFormat(this.y, 0, '.', ',');
}
},
legend: {
enabled: true
},
credits: {
enabled: false
},
series: [{
name: 'Level',
color: colors[0],
data: [{
y: 86,
x: 0.25
}, {
y: 80,
x: 1.25
}, {
y: 95,
x: 2.25
}],
pointWidth: 80
}, {
name: '4A',
data: [90, 88, 97]
}, {
name: '4B',
data: [95, 78, 92]
}, {
name: '4C',
data: [80, 69, 84]
}]
});
});
});
To show in label inside your column you can use below code.
plotOptions: {
column: {
dataLabels: {
enabled: true,
formatter: function() {
return this.series.name;
},
y: 25,
}
}
}

Highcharts dataLabel positioning issue in FF and IE

I'm trying find how to position the labels inside the bars in this case.
<script src="http://code.highcharts.com/highcharts.js"></script>
<script src="http://code.highcharts.com/modules/exporting.js"></script>
<div id="container" style="min-width: 310px; height: 400px; margin: 0 auto">
</div>
$(function () {
$('#container').highcharts({
chart: {
type: 'bar'
},
title: {
text: 'Stacked bar chart'
},
subtitle: { text: 'Some syubtext' },
xAxis: [{ categories: ['2009','2010','2011','2012','2013'] }],
yAxis: {
min: 0,
title: {
text: 'Total fruit consumption'
}
},
legend: {
reversed: true
},
plotOptions: {
bar: { stacking: 'percent',
dataLabels: {
enabled: true,
color: 'white'
}
}
},
series: [{
name: 'John',
data: [28, 23.6, 19.4, 17.5, 22]
}, {
name: 'Jane',
data: [56.7, 60.4, 64, 64.8, 60]
}, {
name: 'Joe',
data: [15.3, 15.9, 16.6, 17.7, 18]
}]
});
});
js fiddle
This works on Chrome, but FF and IE displaces the data labels.
Please advice.

adding verticalAlign: 'top' fixes the issue
dataLabels: {
enabled: true,
color: 'white',
verticalAlign: 'top'
}
