I have this high chart :
and this axis is form by this code:
var xAxis = [{
categories: {{ t|safe }},
labels: {rotation: -90,
style: { fontWeight: 'bold' }},
title: { text: ' '}
},{
categories:{{ secondxlabel|safe }},
linkedTo: 0,
opposite: false,
labels: {rotation: -90,
style:{color: '#2f10a5'}}
}]
;
var yAxis = {
title: {
text: ' '
},
plotLines: [{
value: 0,
width: 1,
color: '#050505'
}],
labels:{
style: {
color: '#a5110e'
}
}
};
And I wish to have this kind of x-axis which is all the repeated month will be group into one only:
Anyone can share me some idea?
Use grouped categories plugin for Highcharts.
xAxis: [{
labels: {
groupedOptions: [{
rotation: 90
}],
rotation: 0
},
categories: [{
name: 'Group 1',
categories: ['Jan', 'Feb', 'Mar']
}, {
name: 'Group 2',
categories: ['Apr', 'May', 'Jun', 'Jul', 'Aug']
}, {
name: 'Group 3',
categories: ['Sep', 'Oct', 'Nov', 'Dec']
}]
}],

I am using apex chart for modern and flexible charts. (https://apexcharts.com/).
Here is my code snippet:
var options = {
chart: {
height: 15,
type: 'line',
zoom: {
enabled: false
}
},
dataLabels: {
enabled: false
},
stroke: {
curve: 'straight'
},
series: [{
name: "Desktops",
data: [10, 5, 2, 15, 12, 11, 10, 1, 0]
}],
title: {
text: 'Product Trends by Month',
align: 'left'
},
grid: {
row: {
colors: ['#f3f3f3', 'transparent'], // takes an array which will be repeated on columns
opacity: 0.5
},
},
xaxis: {
categories: ['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun', 'Jul', 'Aug', 'Sep'],
}
}
var chart = new ApexCharts(
document.getElementById("chart"),
options
);
chart.render();
<div id="chart">
</div>
<script src="https://cdn.jsdelivr.net/npm/apexcharts"></script>
As you can see the height of the chart is a no go. Its cause by the small numbers. When I would have data over 100 it works, but with small numbers, I have this problem. Any solutions to fix this?
~filip
try increasing chart.height to 200.
this allows the chart to be visible.
see following working snippet...
var options = {
chart: {
height: 200,
type: 'line',
zoom: {
enabled: false
}
},
dataLabels: {
enabled: false
},
stroke: {
curve: 'straight'
},
series: [{
name: "Desktops",
data: [10, 5, 2, 15, 12, 11, 10, 1, 0]
}],
title: {
text: 'Product Trends by Month',
align: 'left'
},
grid: {
row: {
colors: ['#f3f3f3', 'transparent'], // takes an array which will be repeated on columns
opacity: 0.5
},
},
xaxis: {
categories: ['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun', 'Jul', 'Aug', 'Sep'],
}
}
var chart = new ApexCharts(
document.getElementById("chart"),
options
);
chart.render();

I am trying to develop a multi axis combo graph using highcharts api with months in x-axis and multiple y axis with 2 axes having percentages and 1 having number. This is similar to what you see in this link. This works fine when you have the y axes data for all 12 months. In some cases y axes data for few months are missing. In that case I still want to show the month in the x axis with no data. Currently if I have y axes data for only 2 months (say June and December), it would show as the data for Jan and Feb instead. Please find the code which I'm using and let me know what can be the resolution for this.
var chartMonthlyData = {
title: {
text: ''
},
xAxis: [{
categories: ['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun',
'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec'],
crosshair: true
}],
yAxis: [{
min: 0,
max: 50,
labels: {
format: '{value} %'
},
title: {
enabled: false
},
opposite: true
}, {
title: {
text: '',
},
labels: {
formatter: function () {
return this.value.toString().replace(/\B(?=(\d{3})+(?!\d))/g, ",");
}
}
}, {
min: 0,
max: 50,
title: {
enabled : false
},
labels: {
enabled: false
},
opposite: true
}],
tooltip: {
shared: true
},
legend: {
layout: 'horizontal',
align: 'right',
x: -30,
verticalAlign: 'top',
y: -5,
floating: true,
backgroundColor: '#FFFFFF'
},
series: [{
color: '#C8102E',
name: 'Delivered',
type: 'column',
yAxis: 1,
data: deliveredMonthly,
tooltip: {
pointFormat: '<span style="color:{point.color}">\u25CF</span> {series.name}: <b>'
+ '{point.y}' +'</b><br/>'
}
}, {
color: '#AAAAAA',
name: 'Open Rate',
type: 'line',
yAxis: 2,
data: openRateMonthly,
lineWidth: 4,
marker: {
enabled: true,
"symbol": "circle"
},
tooltip: {
valueSuffix: ' %'
}
}, {
color: '#5891c8',
name: 'Clickthrough Rate',
type: 'line',
data: clickThroughRateMonthly,
lineWidth: 4,
marker: {
enabled: true,
"symbol": "circle"
},
tooltip: {
valueSuffix: ' %'
}
}]
}
In this image, actual months in x axis are January, June and August. I need the 12 months to be shown in the graph with the y axes data properly tied with months.
Get proper data from server side or update the data before providing to highcharts
data: [49.9, 71.5, 106.4, null, null, null, null, null,null, null, null, null],
add or substitute null to data series with no values corresponding to month in order to have series length same as categories
Fiddle demo
Simply add max parameter inside xAxis object.
API Reference:
http://api.highcharts.com/highcharts/xAxis.max
Example:
http://jsfiddle.net/xkqn4qq7/
There are multiple ways to format your data such that the gaps show up. You can use a 2 dimensional array:
var deliveredMonthly =[[0,4],[5,5],[7,2]],
You can use an array of objects, setting the x & y:
openRateMonthly = [{x:0,y:22},{x:5,y:5},{x:7,y:3}],
And, you can populate a one dimensional array with nulls for your missing data points.
clickThroughRateMonthly = [10,null,null,null,null,12,null,null,50];
In order to guarantee you have all 12 months, you should set the min and max on the xAxis
xAxis: [{
categories: ['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun',
'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec'
],
crosshair: true,
min:0,
max:11
}],

Im trying to add a plot line to a line chart. When the data is same e.g [7.0, 7.0, 7.0] the plot line doesn't show. But when the data is up and down then the plot line shows e.g [7.0, 8.0, 7.0]. Is there a way to make the plot line show when the data is the same? JSFiddle
My high chart set up is:
$(function () {
$('#container').highcharts({
title: {
text: 'Monthly Average Temperature',
x: -20 //center
},
subtitle: {
text: 'Source: WorldClimate.com',
x: -20
},
xAxis: {
categories: ['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun',
'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec']
},
yAxis: {
title: {
text: 'Temperature (°C)'
},
plotLines:[{
value:10,
color: '#ff0000',
width:2,
zIndex:4,
label:{text:'goal'}
}]
},
tooltip: {
valueSuffix: '°C'
},
legend: {
layout: 'vertical',
align: 'right',
verticalAlign: 'middle',
borderWidth: 0
},
series: [{
name: 'Tokyo',
data: [7.0, 7.0, 7.0, 7.0]
}]
});
});
Your problem is connected with how your yAxis look right now. When you have the same y value of your data, your yAxis has the same min and max. For example if you have data: [7.0, 7.0, 7.0, 7.0], your yAxis min and max is equal to 7.
If your plotLine has value:10, you cannot see it in your chart. To see this plotLine you can manually set min and max of your yAxis:
yAxis: {
min: 5,
max: 10,
title: {
text: 'Temperature (°C)'
},
plotLines: [{
value: 10,
color: '#ff0000',
width: 2,
zIndex: 4,
label: {
text: 'goal'
}
}]
},
Here you can see an example: http://jsfiddle.net/g34pk5tc/3/
To make possibility of changing extremes in your yAxis, better idea will be to add series with invisible point, where y value of this point will be equal to value of your plotLine. Here you can see an example how it can work:
function(chart) {
chart.addSeries({
showInLegend: false,
enableMouseTracking: false,
data: [10],
marker: {
enabled: false
}
})
}

I'm really new to javascript and Highcharts so really sorry if this is a dumb question.
I have an object (called val) like this:
Object {month: Array[12], corporate: Array[12], family: Array[12], party: Array[12]}
Each array includes sales value over time for corporate/family/party.
I want to create a line chart in Highcharts with 3 lines (corporate, family, party) over time.
Below is my code:
$(function () {
$('#expandable-3').highcharts({
title: {
text: 'Monthly Average Temperature',
x: -20 //center
},
subtitle: {
text: 'Source: WorldClimate.com',
x: -20
},
xAxis: {
categories: ['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun',
'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec']
},
yAxis: {
title: {
text: 'Temperature (°C)'
},
plotLines: [{
value: 0,
width: 1,
color: '#808080'
}]
},
tooltip: {
valueSuffix: '°C'
},
legend: {
layout: 'vertical',
align: 'right',
verticalAlign: 'middle',
borderWidth: 0
},
series: val
});
});
The chart is showing blank.
Could someone please help me on how to get this work?
Thank you.
If you view the options on the highcharts demo you can see how the series is specified. Highcharts basic line demo
You could change val to something like this:
var val = [
{
name: 'corporate',
data: [1,2,3]
},
{
name: 'family',
data: [1,2,3]
},
{
name: 'party',
data: [1,2,3]
}
];
To convert your data use something like:
Object.keys(val).map(function (key) {
return {
name: key,
data: val[key]
};
});

I tried using this but I am getting only points are changed based on the flag, but I am not getting the line coloured .
here is my code.

});
please help me out. need to get the colored line along with the point.. i m not getting where i m doing wrong, plzzzz help me.
You can use Multicolor series plugin, for example: http://jsfiddle.net/sz0esszz/11/
Simply change type of the series to coloredline and for each of the points set segmentColor, which defines line color between current point and next point.
