<table>

<td><div id="container1" style="width: 300px; height: 300px; margin: 0 auto"></div></td>
<td><div id="container2" style="width: 300px; height: 300px; margin: 0 auto"></div></td>
</tr>
</table>
</body>
</html>
But how can i merge two heat map into one plot sharing same x-axis.


Try doing multiple y axis in same pane like this
yAxis: [
{
opposite : false,
title: {
text: 'HeatMap1'
},
top: 0
},{
opposite : false,
title: {
text: 'HeatMap2'
},
top: 30
}]

Below is the highchart application iam working.In mounted i will call axios post that will fetch x axis lables as array.But the x axis categories of highchart is not updating with the given array
Below is the code
<template>
<div class="container">

<div class="col-md-12">
<div id="container" style="min-width: 100%; max-width:100%; height: 600px; margin: 0 auto"></div>
</div>
</div>
</div>
</template>
<script>
var $ = require('../../node_modules/jquery/dist/jquery.js')
var Highcharts = require('highcharts')
// Load module after Highcharts is loaded
require('highcharts/modules/exporting')(Highcharts)
// Create the chart
$(function () {
Highcharts.chart('container', {
chart: {

marginBottom: 100,

},

}
}
})
})
export default {
data () {
return {
}
},
mounted () {
//will fetch labels from db
var arr = ['computers', 'games']
this.catList = arr
}
}
</script>
<style scoped>
.container{
margin: 0 auto;
}
#container{
margin: 0 auto;
min-width: 100%;
padding: 0;
max-width:100%;

margin: 0 auto;
}
</style>
Please give solution to above problem.

To make categories reactive, you should put Highchart code inside component
Note that in xAxis config, we need to put categories: this.categories
new Vue({
el: '#app',
data() {
return {
chart: null,
categories: []
}
},
mounted() {
this.drawChart()
// example after pull data
var arr = ['computers', 'games']
const vm = this;
setTimeout(function() {
vm.categories = arr
vm.drawChart()
}, 2000)
},
methods: {
drawChart() {
if (this.chart) {
this.chart.destroy();
}
this.chart = Highcharts.chart('container', {
chart: {
marginTop: 120,
marginBottom: 100,
type: 'bar'
},
credits: {
enabled: false
},
exporting: {
enabled: false
},
legend: {
enabled: true,
layout: 'vertical',
backgroundColor: '#FFFFFF',
floating: true,
align: 'right',
verticalAlign: 'bottom',
margin: 50,
reversed: true
},
title: {
text: null
},
tooltip: {},
plotOptions: {
series: {
stacking: 'normal'
}
},
series: [{
name: 'viewers',
color: '#006666',
pointWidth: 40,
data: [8, 16]
}, {
name: 'calls',
color: '#00FF00',
pointWidth: 40,
data: [7, 14]
}, {
name: 'chats',
color: '#FF8C00',
pointWidth: 40,
data: [8, 16]
}],
xAxis: {
categories: this.categories,
labels: {
overflow: 'right',
display: 'block',
align: 'left',
x: 5,
style: {
fontSize: '1em',
color: '#000',
width: '500px'
}
}
},
yAxis: {
min: 0,
allowDecimals: false,
title: {

It's problem with your formatter which returns default value, see API. If you want to keep numeric symbols, call defaultLabelFormatter.
Demo: http://jsfiddle.net/BlackLabel/uL2jx0t9/1/
yAxis: {
labels: {
formatter: function() {
return '$' + this.axis.defaultLabelFormatter.call(this);
}
}

High chart problwm with multiple axes with dynamic data

I am trying to generate multi axes graph uding highchart as below.
But its not working, array generation and all are quite fine.
If i hardcode totalNoOfLabels and totalLabelsSize then its working. Please suggest:
<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 () {
var result=[{"date":"2013-05-01","propertiesList": {"labelsCount":"14","totalSize":"62.62"}},{"date":"2013-05-04","propertiesList":{"labelsCount":"4","totalSize":"22.43"}},{"date":"2013-05-03","propertiesList":{"labelsCount":"7","totalSize":"34.09"}},{"date":"2013-05-02","propertiesList":{"labelsCount":"13","totalSize":"67.51"}},{"date":"2013-05-05","propertiesList":{"labelsCount":"3","totalSize":"11.65"}}];
var totalNoOfLabels=[];
var totalLabelsSize=[];
var dates=[];
dailyStatList = JSON.stringify(result);
var statsObj = $.parseJSON(dailyStatList);
$.each(statsObj, function() {
dates.push(this.date);
totalNoOfLabels.push(this.propertiesList.labelsCount);
totalLabelsSize.push(this.propertiesList.totalSize);
});
$('#container').highcharts({
chart: {
zoomType: 'xy'
},
title: {
text: 'Info'
},
xAxis: [{
categories: dates
}],
yAxis: [{ // Primary yAxis
labels: {
style: {
color: '#89A54E'
}
},
title: {
text: 'No of labels',
style: {
color: '#89A54E'
}
}
}, { // Secondary yAxis
title: {
text: 'Size ',
style: {
color: '#4572A7'
}
},
labels: {
style: {
color: '#4572A7'
}
},
opposite: true
}],
tooltip: {
shared: true
},
legend: {
layout: 'vertical',
align: 'left',
x: 120,
verticalAlign: 'top',
y: 100,
floating: true,
backgroundColor: '#FFFFFF'
},
series: [{
name: 'Labels',
color: '#4572A7',
type: 'column',
yAxis: 1,
data: totalNoOfLabels
}, {
name: 'Size',
color: '#89A54E',
type: 'spline',
data: totalLabelsSize
}]
});
});

labelsCount and totalSize should be numbers, not strings. Parse that values, or put in JSON as numbers and will work properly.

How can I remove the gap between x axis and the frame in HIGHCHARTS and set the series labels in single line

I am new to this forum and have two questions.
I just want know if we can remove the gap behind the axis in High Charts. I haven't found any option in the API.
How to get the series label in single line.
I am not able to post the image as I am a new user.

How to get the series label in single line
For this, you need to use the property Rotation as
rotation: 90
Check the API.
Setting this property also answers your question 1.
Here you find the Demo
