Plotting multiple points in highchart timeseries - highcharts

I have data that looks like this in JSON format. I have two data series with same time line. When I try to plot them in highstock, all my time-stamps are shown as starting in 1970s. Can anyone point me what would be wrong with my JSON format?
Reason I am not using - pointStart and pointInterval: is because sometime pointIntervals can be irregular and hence need to send in the dates.
{
"chart_data": {
"dates": [
1406876400000,
1406876700000,
1406877000000,
1406877300000,
1406877600000,
1406877900000,
1406878200000,
1406878500000,
1406878800000
],
"values": [
{
"data": [
54,
50,
62,
65,
65,
55,
51,
53,
57
]
},
{
"data": [
84,
70,
80,
78,
77,
84,
73,
83,
77
]
}
]
}
}
My Javascript method to display this data is below.
<script type="text/javascript">
$(document).ready(function() {
var chartOptions = {
chart: {
renderTo: 'chart_panel',
type: 'line',
zoomType: 'x'
},
legend: {
layout: 'vertical',
align: 'right',
verticalAlign: 'middle',
borderWidth: 0
},
title: {text: 'Temperature & Humidity' },
subtitle: {text: 'My-Text' },
xAxis: {
type: 'datetime',
dateTimeLabelFormats: {
month: '%e. %b',
day: '%b %e',
hour: '%b %e',
year: '%b'
}
},
yAxis: {
min: 0,
title: {
text: 'Temperature (°F)/Humidity (%)'
},
plotLines: [{
value: 0,
width: 1,
color: '#808080'
}]
},
series: [{}],
rangeSelector : {
inputEnabled: true,
selected: '0'
},
};
var chartDataUrl = '{% url "chart_data_json" object.id %}';
function loadChart() {
$.getJSON(chartDataUrl,
function(data) {
var seriesOptions = [];
var obj1 = {};
var obj2 = {};
avgByDayOptions.xAxis.categories = data['chart_data']['dates'];
obj1.name = "Temperature";
obj1.data = data['chart_data']['values'][0]['data'];
obj2.data = data['chart_data']['values'][1]['data'];
obj2.name = "Humidity";
seriesOptions[0] = obj1;
seriesOptions[1] = obj2;
chartOptions.series = seriesOptions;
var chart = new Highcharts.StockChart( chartOptions,
function(chart){
// apply the date pickers
setTimeout(function(){
$('input.highcharts-range-selector', $('#'+chart.options.chart.renderTo))
.datepicker()
},0)
}
);
Highcharts.setOptions({ global: { useUTC: false } });
});
}
loadChart();
});

It was may bad once I passed the data in following format everything started work as expected. Just posting reply to my own question in case someone runs into similar issue?

Highchart Donut chart not circular

I'm using Highchart to create a donut chart with a rounded corner. Unfortunately, the chart is not fully circular.
var data2 = [
{
"data": [
{

"y": 50,
"color": "#2CA02C",
"sliced": true
},
{

"sliced": true
},
{
"name": "Neutral",
"y": 25,
"color": "#E5CF73",
"sliced": true
}
]
}
]
window.mychart = Highcharts.chart('container', {
chart: {
type: 'pie',
plotShadow: false,
},
credits: {

plotOptions: {
pie: {

}
}
},
title: {
verticalAlign: 'middle',
floating: true,

},
legend: {
},
series: data2,
});
Here is the jsfiddle link to it:

Only one point can be sliced, so use data without the sliced property or set slicedOffset to 0.

Column Labels in Sankey Charts in Highcharts

I've been working on a visualisation using Sankey chart using Highcharts library. It looks like below.
I need help with adding labels to each column as highlighted in the above image. I couldn't find any workaround using formatters since there are no x & y axes available in sankey.
It would be great someone here helps me with doing it.
you can find my jsfiddle here.
EDIT: I was able to plot the x & y axes now, but trying to place the labels exactly below each column. Broken fiddle link updated.

You can add the labels by using renderer.text method. Example below:
const labels = ['column 1', 'column 2', 'column 3'];
Highcharts.chart('container', {
chart: {
spacingBottom: 50,
events: {
render: function() {
const positions = [30, this.chartWidth / 2, this.chartWidth - 30];
if (this.customLabels) {
this.customLabels.forEach((customLabel, i) => {
customLabel.attr({
x: positions[i],
y: this.chartHeight - 20
});
});
} else {
this.customLabels = [];
labels.forEach((label, i) => {
this.customLabels.push(
this.renderer.text(labels[i])
.attr({
x: positions[i],
y: this.chartHeight - 20,
align: 'center'
})
.css({
fontSize: '12px'
})
.add()
);
});
}
}
}
},
...
});

How can I get every bar in different colour using Highchart?

The Highchart graph code is shown below I want every bar label color is different. Currently, I'm getting the same color in bar
Highcharts.chart('container', {
chart: {
type: 'column',
},
title: {
text: 'Popular '
},
credits:{
enabled:false
},
xAxis: {
max: 20,
type: 'category',
style:{
fontSize: '12px'
}
},
yAxis: {
min: 0,
allowDecimals:false,
title: {
text: 'Number of applications',
style:{
fontSize: '12px'
}
},
gridLineWidth:0,
minorGridLineWidth: 0,
tickLength: 5,
tickWidth: 1,
tickPosition: 'inside',
lineWidth:1
},
scrollbar: {
enabled: true
},
legend: {
enabled: false
},
tooltip: {
pointFormat: 'hi'
},
series: [{
name: Stats',
data: data,
color:'#2ecc71',
pointWidth: 25,
}],
Data format is :
[
[
"Qualcom",
17
],
[
"The ram",
12
],
[
"Aoperty",
8
],
[
"Ob.",
8
],
[
"Sugh",
8
],
]
The output is shown in the picture I want every bar is in a different color can you help me?
Referring to comments you can set a specific color to a single point by adding a color property programmatically to its object like that:
series: [{
data: [
["Qualcom", 17],
{
name: "The ram",
y: 12,
color: 'red'
},
["Aoperty", 8],
["Ob.", 8],
["Sugh", 8]
],
color: '#2ecc71'
}]
API reference:
https://api.highcharts.com/highcharts/series.column.data.color
Demo:
https://jsfiddle.net/BlackLabel/craqy1sv/1/
If you want to add a specific color to a point when a condition is matched you can loop through each series point in chart load event and update a matched point:
chart: {
type: 'column',
events: {
load: function() {
var chart = this,
series = chart.series[0];
series.points.forEach(function(point) {
if (point.name === 'The ram') {
point.update({
color: 'red'
})
}
});
}
}
}
API reference:
https://api.highcharts.com/highcharts/chart.events.load
https://api.highcharts.com/class-reference/Highcharts.Point#update
Demo:
https://jsfiddle.net/BlackLabel/jmuoevz1/
You need to set colorByPoint :true to use different colors like that
series: [{
name: 'Stats',
data: [
[
"Qualcom",
17
],
[
"The ram",
12
],
[
"Aoperty",
8
],
[
"Ob.",
8
],
[
"Sugh",
8
]
],
colorByPoint: true,
pointWidth: 25,
}]

Highchart legend over columns

is it possible in highchart to add the legend in each column with keeping
the value or label of each coulmn on top of the column like the attached image and this is my code on jsfiddle enter link description here
$('#container').highcharts({
"chart": {
"type": "column",
"style": {
"fontFamily": "Arial",
"fontSize": 12
},
"backgroundColor": "transparent",
"width": 460
},
"plotOptions": {
"series": {
"dataLabels": {
"enabled": true,
"format": "${y}"
},
"pointPadding": 0,
"groupPadding": 0.1
}
},
"xAxis": [{
"categories": [
"Jan",
"Feb",
"Mar"],
}],
"series": [{
"name": "2014",
"color": "#231E1E",
"marker": {
"radius": 3
},
"showInLegend": true,
"connectNulls": true,
"tooltip": [
],
"data": [
10,
20,
30]
}, {
"name": "2015",
"color": "#1DBEDE",
"marker": {
"radius": 3
},
"showInLegend": true,
"connectNulls": true,
"tooltip": [
],
"data": [
12,
22,
32]
}]
});
You can use the plotOptions.series.dataLabels.formatter instead of format:
dataLabels: {
enabled: true,
useHTML: true,
y: 30,
formatter: function() {
return "$" + this.y + "<br><br><br>" +
"<div style='-webkit-transform: rotate(90deg); -moz-transform: rotate(90deg); -o-transform: rotate(90deg);'>" +
this.series.name + "</div>";
}
}
You can tell the chart exactly the way you want the labels to be shown. this.y is the dollar values and this.series.name is the name of the series which are 2014 and 2015. y: 30 is where the label should be placed in respect to the top of the column. Here's a DEMO.
PS: The problem is that you cannot have two datalabels for each column. You either have to set the location for the top label (as mentioned in my answer) or set it for the bottom labels in this example. As you can see there are some problems in each example, but you can't have both. However there could be a workaround like this, but its not clean.
You can try to use stackLabels. Of course that solution will work only when you don't use stacking at all. See demo: http://jsfiddle.net/LLExL/4855/
Code:
yAxis: {
stackLabels: {
enabled: true,
formatter: function() {
return "$" + this.total;
}
}
},
"plotOptions": {
"series": {
stacking: "normal",
"dataLabels": {
"enabled": true,
rotation: -90,
"format": "{point.series.name}"
},
"pointPadding": 0,
"groupPadding": 0.1
}
},
Regarding aligning labels to the bottom, see this question.
I made some changes on solution of #Raeen to be exactly what i want
and here is the example demo
enter code jQuery('#container').highcharts({
"chart": {
"type": "column",
"style": {
"fontFamily": "Arial",
"fontSize": 12
},
"backgroundColor": "transparent",
"width": 460
},
title:{
text:''
},
tooltip: {
enabled: false
},
"plotOptions": {
"series": {
"dataLabels": {
"inside":true,
"enabled": true,
useHTML: true,
y: 30,
formatter: function() {
var html ='';
labelHeight = this.point.shapeArgs.height-15;
html += '<div class="data-label-wrapper" style="height:'+labelHeight+'px;">';
html += '<span style="color:'+this.series.color+';">$'+this.y+'</span>';
html += '<span class="serie-name" style="top:'+(labelHeight-25)+'px">'+this.series.name+'</span>';
html += '</div>';
return html ;
}
},
"pointPadding": 0,
"groupPadding": 0.1
}
},
"xAxis": [{
"categories": [
"Jan",
"Feb",
"Mar"],
}],
"series": [{
"name": "2014",
"color": "#231E1E",
"marker": {
"radius": 3
},
"showInLegend": false,
"connectNulls": true,
"tooltip": [
],
"data": [
10,
20,
30]
}, {
"name": "2015",
"color": "#1DBEDE",
"marker": {
"radius": 3
},
"showInLegend": false,
"connectNulls": true,
"tooltip": [
],
"data": [
12,
22,
32]
}] });
and now what i need if its possible to controll the number of gridlines numbers
to be like 3 instead of 8 that would be perfect.

Highchart - show heatmap legend by category

I would like to use the heatmap to generate a status overview of a machine for a given day. The states show up as I want but I have a question about the legend. Can I show a 'traditional' legend that shows the states and their colors.
Highchart fiddle: http://jsfiddle.net/p7v2f117/7/
$(function () {
$('#container').highcharts({
chart: {
type: 'heatmap',
marginTop: 40,
marginBottom: 40
},
title: {
text: 'HIGHCHART - Machine State on 1/7/2015'
},
xAxis: { // minute interval
categories: ['00', '15', '30', '45']
},
yAxis: { // hour
categories: ['20:00', '21:00'],
title: null
},
colorAxis: {
min: 0,
minColor: '#FFFFFF',
maxColor: Highcharts.getOptions().colors[0]
},
legend: {
align: 'right',
layout: 'vertical',
margin: 0,
verticalAlign: 'top',
y: 25,
symbolHeight: 320
},
tooltip: {
formatter: function () {
return '<b>' + this.series.yAxis.categories[this.point.y] + ' (' + this.series.xAxis.categories[this.point.x] + 'min)</b>' + '<br>state: <b>' + this.point.value + '</b><br>More details go here'
}
},
series: [{
name: 'Machine State',
borderColor: '#000000',
borderWidth: 1,
data: [{
x: 0,
y: 0,
value: 'RUN',
color: '#00FF00'
}, {
x: 1,
y: 0,
value: 'RUN',
color: '#00FF00'
}, {
x: 2,
y: 0,
value: 'RUN',
color: '#00FF00'
}, {
x: 3,
y: 0,
value: 'IDLE',
color: '#00FFFF'
}, {
x: 0,
y: 1,
value: 'IDLE',
color: '#00FFFF'
}, {
x: 1,
y: 1,
value: 'DOWN',
color: '#FF0000'
}, {
x: 2,
y: 1,
value: 'PM',
color: '#C0C0C0'
}, {
x: 3,
y: 1,
value: 'Marathon',
color: '#FFCCFF'
}, ],
dataLabels: {
enabled: false
}
}]
});
});
I am trying to basically get the same behavior that I can get in Fusion charts, where the color is automatically driven by the status field (text) and it shows the categories. The fact that they are clickable is nice but not necessary.

}
});
chart.render();

Is there a simple way to not show the legend at all?
I can certainly convert the states back to a number if that makes more sense.

You need to cover default parameter for highmaps:
var H = Highcharts;
H.seriesTypes.heatmap.prototype.axisTypes = ['xAxis', 'yAxis'],
H.seriesTypes.heatmap.prototype.optionalAxis = null;
Example: http://jsfiddle.net/ww6Lbnc5/
