I'm working with highchart and I have the following chart working.
However, I need the next value starts at the point of the previous value.
Can someone help me please?
I use this function to generate chart
function generateChart(chartUrl, id) {
let options = {};
$.ajax({
url: chartUrl,
data: {name: id},
success: function (data) {
options.series[0].data = data;
// Get categories dynamicaly, not harcoded
for(let i=0;i<data.length;i++){
options.xAxis.categories.push(data[i][0]);
}
$(`#${id}`).highcharts(options);
}
});
}
And this code to Generate Data and Efects on chart
function generateEfectsChart() {
let options = {
chart: {
type: 'column'
},
title: {
text: ''
},
exporting: {
enabled: false
},
credits: {
enabled: false
},
xAxis: {
lineColor: '#FFFFFF',
lineWidth: 0,
gridLineColor: '#DADBDF',
categories: [],
},
yAxis: {
lineColor: '#FFFFFF',
lineWidth: 0,
gridLineColor: '#DADBDF',
plotBands: [{
color: '#000000', // Color value
from: 0, // Start of the plot band
to: 0 // End of the plot band
}],
title: {
text: ''
},
legend: {

},
plotOptions: {

dataLabels: {
enabled: true,
format: '{point.y}'
},
turboThreshold: 0
}
},
series: [{
negativeColor: '#ED4D5F'
}]
};
return options;
}
Use the waterfall series type.
Highcharts.chart('container', {
chart: {
type: 'waterfall'
},
...,
});

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]
// How can we show a tree map at the bottom with the values above
// upon clicking on the point 0.63 for the third week of sample 5 ??

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
}]
})
}
}
},
...
}
}

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/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);
}
}
},

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);
}
}
Working example: https://jsfiddle.net/ewolden/xu058sgp/46/
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]

};
// 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({

display_text: 'fill',

});
});
</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.
