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.

I am working on highchart. I am trying to build a bar chart with a single entry against each category. Right now I am working on an example basic-bar. Below is the output
Expected Output
I want a single entry against each category. For example against April, I want only one bar not multiple and so on
Here is the working jsFiddle
you just use the parameter visible:
Highcharts.chart('container', {
chart: {
type: 'bar'
},
title: {
text: 'Historic World Population by Region'
},
subtitle: {
text: 'Source: Wikipedia.org'
},
xAxis: {
categories: ['Africa', 'America', 'Asia', 'Europe', 'Oceania'],
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: 80,
floating: true,
borderWidth: 1,
backgroundColor:
Highcharts.defaultOptions.legend.backgroundColor || '#FFFFFF',
shadow: true
},
credits: {
enabled: false
},
series: [
/*{

}, */
{

data: [1216, 1001, 4436, 738, 40]
}]
});

I am trying to re-create the same line chart that is seen below using the Highcharts library. I can't figure out how can I display the date on the x-axis the same way it is shown on the image, and also why my third data series is not getting displayed?
Here's my code:

xAxis: {
crosshair: true,
title: { text: 'Date' },

yAxis: {

},

You need to change your data into the array of arrays, where nested array includes the x date format, something like:
[[ x date in miliseconds, y value]]
You can use the pointStart & pointInterval features:
https://api.highcharts.com/highcharts/series.line.pointStart
https://api.highcharts.com/highcharts/series.line.pointInterval
You can define wanted a array of categories that you want to display on the xAxis - just like is done in your example
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;
}
}

I'm trying to figure out if there is some way to plot a line per category in highcharts, i've tried for a while following this doc and my current chart looks like this:
What i want to achieve is something like this:
with each line stoping on the next category, this way i can set "goals" per category.
My code so far
Highcharts.chart('container', {
chart: {
type: 'bar'
},
title: {
text: 'Historic World Population by Region'
},
subtitle: {
text: 'Source: Wikipedia.org'
},
xAxis: {
categories: ['Africa', 'America', 'Asia', 'Europe', 'Oceania'],
title: {
text: null
}
},
yAxis: {
min: 0,
title: {
text: 'Population (millions)',
align: 'high'
},
labels: {
overflow: 'justify'
},
plotLines: [{
color: 'red',
value: 300,
width: 2
}]
},
tooltip: {
valueSuffix: ' millions'
},
plotOptions: {
bar: {
dataLabels: {
enabled: false
}
}
},
legend: {
layout: 'vertical',
align: 'right',
verticalAlign: 'top',
x: -40,
y: 80,
floating: true,
borderWidth: 1,
backgroundColor: ((Highcharts.theme && Highcharts.theme.legendBackgroundColor) || '#FFFFFF'),
shadow: true
},
credits: {
enabled: false
},
series: [{
name: 'Gastos',
data: [107, 31, 635, 203, 2],
color: '#f25a41'
}, {
name: 'Renda',
data: [133, 156, 947, 408, 6],
color: '#5c90f9'
}]
});
The easiest way would be to create custom marker for each category using Renderer.path() function.

Example:

I have a Highchart in my web application. In the browser it displays normally which is as follows:
But when I export the chart it flips the axis and I end up with the following image:
Following are the options I am using for my Highchart.
var options = ({
chart: {
renderTo: 'chartDiv'
},
credits: {
enabled: false
},
title: {
text: ''
},
subtitle: {
text: ''
},
xAxis: {
type: 'datetime',
tickInterval: 7200 * 10000,
allowDecimals:false,
labels: {
format: '{value}',
rotation: 30,
align: 'left',
},
title: {
text: 'Date'
}
},
yAxis: [{
title: {
text: 'No. of rings'
},
min: 0
},
{ // Secondary yAxis
gridLineWidth: 0,
min: 0,
title: {
text: 'Accumulative Rings',
style: {
color: Highcharts.getOptions().colors[0]
}
},
labels: {
format: '{value} Ring',
style: {
color: Highcharts.getOptions().colors[0]
}
},
opposite: true,
}
],
tooltip: {
shared: true
},
legend: { backgroundColor: 'rgba(211,223,181,0.6)', layout: 'vertical', align: 'left', verticalAlign: 'top', floating: true, borderWidth: 0, x: 70 },
plotOptions: {
spline: {
marker: {
enabled: false
},
}
}
});
I have three series in my chart, the bar chart can have 0 values.
The data is coming from an ajax service, which I put in an array and then add to chart as follows:
chart.addSeries({
type: 'bar',
name: 'Rings per day ',
data: barData,
pointInterval: mainInterval
});
chart.addSeries({
type: 'spline',
name: 'Accumilative rings ',
data: spline1Data,
yAxis: 1,
});
chart.addSeries({
type: 'spline',
name: 'Planned Progress ',
data: spline2Data,
yAxis: 1,
color: "#FF0000"
});
What's wrong with my chart?
bar series is the key part. bar series forces chart to be rendered flipped. In your case use column. It displays differently on your browser because, most probably, you have an old version of Highcharts.
