How to display a highchart with more than one line? - javascript

I am having a list name aaa. It is an list of list
aaa[0] = [[{'a',1},{'b',2}]
aaa[1] = [[{'q',2},{'bd',0}]
aaa[2] = [[{'sa',3},{'bs',6}]
aaa[2] = [[{'sa',5},{'vb',8}]
I got the response from the model
Now I need to populate this value into Chart
My Chart will contain four lines for aaa[0] ,aaa[1] ,aaa[2] ,aaa[3]
Here is my High Chart Code
<script>
$(document).ready(function () {
//Default time zone
moment.tz.setDefault("America/New_York");
// Global option to disable UTC time usage
Highcharts.setOptions({
global: {
useUTC: false
}
});
// Chart configurations
var options = {
chart: {
renderTo: 'container2',
type: 'area',
marginRight: 45,
zoomType: 'x'
},
title: {
text: 'aaaa'
},
xAxis: {
type: 'datetime',
minRange: 8 * 24 * 3600000,
labels: {
format: '{value:%m-%d-%Y}',
rotation: 45
}
},
yAxis: {
title: {
text: 'count'
},
labels: {
formatter: function () {
return this.value;
}
}
},
plotOptions: {
area: {
marker: {
enabled: true,
symbol: 'circle',
radius: 2,
states: {
hover: {
enabled: true
}
}
},
lineWidth: 1,
threshold: null
}
},
series: [{
fillOpacity: 0.1,
name: 'aaa',
pointInterval: 24 * 3600 * 1000,
pointStart: 1375295400000,
data: GetPercentage()
}]
};
// Rendering the Highcharts
chart = new Highcharts.Chart(options);
function GetPercentage() {
var data = #Html.Raw(JsonConvert.SerializeObject(Model.aaa));
// alert(data)
#foreach(var val in Model.aaa) //loop of getting a list from aaa
{
var percentages = [];
for (var x = 0; x < #val.Count; x++)
{
//Here I need to push the list
}
//percentages.sort(SortByDate);
// return percentages;
}
}
//Sort the array based on first array element
function SortByDate(a,b){
//alert(a[0] +" - " +b[0]);
return (a[0] - b[0]);
}
//Timeout function to reload page on everyone hour
setTimeout(function () {
location.reload(true);
}, 60* 60 * 1000);
//Progress bar to display feed delivery percentage
$('.progress .progress-bar').progressbar({
transition_delay: 500,
display_text: 'fill',
refresh_speed: 500
});
});
</script>
Could anyone help me to diplay a chart with four lines ?
Thanks in advance


Here you can see the series is an object array
$(function () {
$('#container').highcharts({
chart: {
type: 'bar'
},
title: {
text: 'Fruit Consumption'
},
xAxis: {
categories: ['Apples', 'Bananas', 'Oranges']
},
yAxis: {
title: {
text: 'Fruit eaten'
}
},
series: [{
name: 'Jane',
data: [1, 0, 4]
}, {
name: 'John',
data: [5, 7, 3]
}]
});
});
You should add more objects into series array to create more than one line.

Highcharts how to add treemap upon click event on line chart?

Anyone know how to add treemap upon click event on line chart point? Here's my JSFiddle link:
https://jsfiddle.net/ssoj_tellig/d6pfv1bg/19/
When I click on the line chart on the point 0.63 at the third week of sample5, I'd like a treemap to appear at the bottom with the values loaded in var mytreemap_data (or any other values for the demo, doesn't matter). I'd like to understand how it'd work.
Many thanks for your help!
var mytreemap_data = [1528675200000,0.1,0.2,0.3,0.15,0.25]

Use click event callback function for a point and create another chart with treemap series, for example:
plotOptions: {
series: {
point: {
events: {
click: function() {
Highcharts.chart('treemapContainer', {
series: [{
type: 'treemap',
data: mytreemap_data
}]
})
}
}
},
...
}
}

Show data as a live stream, Highcharts

So What I have is a set of data stored, which I am able to access in Highchart easily. but Now what I need is to show the data as a live stream
like the following example :
https://www.highcharts.com/demo/dynamic-update
What I have done so far is Here :
<script type="text/javascript">
var xValues = [];
xValues = [1,4,3,9,3,4,4,6,4,5,3,4,3,3,1,3,2,3,2,3,4,4,3,3,4,3,5,3,6,7,3,2,5,7,4,6,7,3,6,7,4,7,4,7,3,2,5,6,7,4,3,4,6,6,7,4,6,6,7,3,6,7,3,2,4,5,6,5,9,8,4,6,2,1,5,8,5,8,2,6,3,8,4,7,3,6,1,5,8,0,2,4,7,5,8,3,7,9,3,7];
Highcharts.chart('ppg', {
chart: {
type: 'line'
},
title: {
text: 'ECG Data'
},
subtitle: {
text: ''
},
xAxis: {
crosshair: false
},
yAxis: {
title: {
text: 'Peaks'
}
},
tooltip: {
enable: false
},
plotOptions: {
column: {
pointPadding: 0.2,
borderWidth: 0
}
},
series: [{
name: '',
lineWidth: 2,
data: xValues,
animation: {
duration: 5000
}
}]
});
</script>.
How can my data flow like the above example? in 10 10 patches.
Here is the Working JSFiddle:
https://jsfiddle.net/abnitchauhan/3vj2afnt/

You can initially add only the first 10 points and then use chart load event function and set interval to add remaining points with shift argument:
var xValues = [],
counter = 11,
startValues;
xValues = [...];
startValues = xValues.slice(0, counter);
var chart = Highcharts.chart('ppg', {
chart: {
type: 'line',
events: {
load: function() {
var chart = this,
interval = setInterval(function() {
chart.series[0].addPoint(xValues[counter], true, true);
counter++;
if (counter === xValues.length - 1) {
clearInterval(interval);
}
}, 1000);
}
}
},
...
});

API Reference:
https://api.highcharts.com/highcharts/chart.events.load
https://api.highcharts.com/class-reference/Highcharts.Series#addPoint

In your code event is missing which will trigger change per sec.
Something like this. I have used random number.
var xValues = [];
xValues = [1,4,3,9,3,4,4,6,4,5,3,4,3,3,1,3,2,3,2,3,4,4,3,3,4,3,5,3,6,7,3,2,5,7,4,6,7,3,6,7,4,7,4,7,3,2,5,6,7,4,3,4,6,6,7,4,6,6,7,3,6,7,3,2,4,5,6,5,9,8,4,6,2,1,5,8,5,8,2,6,3,8,4,7,3,6,1,5,8,0,2,4,7,5,8,3,7,9,3,7];
Highcharts.chart('ppg', {
chart: {
type: 'line',
events: {
load: function () {
// set up the updating of the chart each second
var series = this.series[0];
setInterval(function () {
var x = Math.random();
y = Math.random();
series.addPoint([x, y], true, true);
}, 1000);
}
}
},
title: {
text: 'ECG Data'

Alignment issue in dynamically updated highstock having multiple series

I am creating a dynamic updated highstock chart with 2 series but at start one series is rendering in wrong place. And when I resize the selection in navigator the series comes back to its correct place.
Here is the config of highstock:
Highcharts.setOptions({
global: {
useUTC: false
}
});
var groupingUnits = [['millisecond', [1, 2, 5, 10, 20, 25, 50, 100, 200, 500]],
['second',[1, 2, 5, 10, 15, 30]],
['minute',[1, 2, 5, 10, 15, 30]],
['day',[1]]
];
// Create the chart
Highcharts.stockChart('container', {
chart: {
events: {
load: function () {
// set up the updating of the chart each second
var series = this.series[0];
var series1 = this.series[1];
setInterval(function () {
var x = (new Date()).getTime(), // current time
y = Math.round(Math.random() * 100);
series.addPoint([x, y], true, false);
series1.addPoint([x, y], true, false);
}, 500);
}
}
},
rangeSelector: {
buttons: [{
count: 1,
type: 'minute',
text: '1min'
},
{
count: 3,
type: 'minute',
text: '3min'
}, {
count: 5,
type: 'minute',
text: '5min'
}, {
type: 'all',
text: 'All'
}],
inputEnabled: false,
selected: 3
},
exporting: {
enabled: false
},
title: {
text: 'Live Chart'
},
yAxis: [
{
labels: {
align: 'right',
x: -3
},
title: {
text: 'Line'
},
height: '60%',
lineWidth: 2,
resize: {
enabled: true
}
},
{
labels: {
align: 'right',
x: -3
},
title: {
text: 'Volume'
},
top: '65%',
height: '35%',
offset: 0,
lineWidth: 2
}],
tooltip: {
split: true
},
series: [
{
type: 'line',
name: 'OHLC',
data: [[]],
dataGrouping: {
units: groupingUnits
}
},
{
type: 'column',
name: 'Volume',
data: [[]],
yAxis: 1,
dataGrouping: {
units: groupingUnits
}
}
]
});
I have created a fiddle for the same:
https://jsfiddle.net/xu058sgp/23/
I have tried changing the height and top property of yAxis but nothing seems to fix this issue. I am not sure but it can be due to the frequency in which the data is getting updated.
Can someone point me out what I am doing wrong here.

As a workaround you could initialize the series and then remove the points before adding your own points.
Initialization:
series: [{
type: 'line',
name: 'OHLC',
data: [0], //added this 0
dataGrouping: {
units: groupingUnits
}
}, {
type: 'column',
name: 'Volume',
data: [0], //added this 0
yAxis: 1,
dataGrouping: {
units: groupingUnits
}
}]
Then, remove the points before adding new ones:
events: {
load: function () {
// set up the updating of the chart each second
var chart = this
var series = this.series[0];
var series1 = this.series[1];
//Remove 0 data
series.setData([], false); //false to avoid redrawing, so we only redraw once per update
series1.setData([], false);
//update graph
setInterval(function () {
var x = (new Date()).getTime(), // current time
y = Math.round(Math.random() * 100);
series.addPoint([x, y], false, false);
series1.addPoint([x, y], false, false);
//redraw graph
chart.redraw();
}, 500);
}
}

Loading json data to highstocks with multiple series and adding TimeStamp to xAxis

How to load json data to multiple series and add Time to xAxis in HighStock?
And any idea how to add multiple yAxis on the right and left of the HighStock chart?

Highchart tick interval

I cannot seem to figure out how to set my tick interval correctly.
Need to have an hourly tick on the X axis.
The data is minute based.
Javascript:
$(function () {
var chart;
$(document).ready(function() {
chart = new Highcharts.Chart({
chart: {
renderTo: 'container',
type: 'spline'
},
title: {
text: 'Temperature Today'
},
xAxis: {
type: "datetime",
categories: time,
dateTimeLabelFormats: {
day: '%h'
},
minTickInterval: 24 * 36000000 * 1000,
},
yAxis: {
title: {
text: 'Temperature'
},
minorGridLineWidth: 0,
gridLineWidth: 0,
alternateGridColor: null
},
tooltip: {
formatter: function() {
return ''+
Highcharts.dateFormat('%e. %b %Y, %H:00', this.x) +': '+ this.y;
}
},
plotOptions: {
spline: {
lineWidth: 4,
states: {
hover: {
lineWidth: 5
}
},
marker: {
enabled: false,
states: {
hover: {
enabled: true,
symbol: 'circle',
radius: 5,
lineWidth: 1
}
}
},
}
},
series: [{
name: 'Asen',
data: temp
}]
,
navigation: {
menuItemStyle: {
fontSize: '6px'
}
}
});
});
});
Data arrays:
temp = [-4.39,-4.39,-4.33,-4.33,-4.33,-4.33,-4.33]
time = [1359910725000,1359910786000,1359910848000,1359910908000,1359910968000,1359911028000,1359911089000,1359911150000]

First of all, remove the 'categories' property on xAxis, this has no meaning on a datetime axis. Note that datetime axes are based on milliseconds, so an interval of one hour is expressed as 3600 * 1000. See API highcharts, tickInterval
use this config for the xAxis.
xAxis: {
type: "datetime",
dateTimeLabelFormats: {
day: '%H'
},
tickInterval: 3600 * 1000
},
See here for a working demo on JS Bin.

You should use tickInterval with value: 3600 * 1000
