Dynamically load in series HighCharts

I am trying to dynamically load in a number of series, depending on projects chosen by the user. I am using Laravel 5.2, PHP 5.6 and HighCharts.
I have managed to load in one JSON file, which is generated when the user selects projects. But I would like it if the JavaScript could parse the different series from the JSON file and dynamically load this into the series.
This is the code which I am using:
$(function () {
// Set up the chart
var processed_json = new Array();
$.getJSON('/uploads/test.json', function(data) {
for (i = 0; i < data.length; i++) {
processed_json.push([data[i].key, data[i].value]);
}
var chart = new Highcharts.Chart({
chart: {
renderTo: 'container',
type: 'column',
options3d: {
enabled: true,
alpha: 0,
beta: 0,
depth: 0,
viewDistance: 25
}
},
title: {
text: 'Grades'
},
subtitle: {
text: 'Dataset'
},
plotOptions: {
column: {
depth: 0
}
},
series: [{
name: 'Grades',
data: processed_json
}],
credits: {
enabled: false
}
});
function showValues() {
$('#alpha-value').html(chart.options.chart.options3d.alpha);
$('#beta-value').html(chart.options.chart.options3d.beta);
$('#depth-value').html(chart.options.chart.options3d.depth);
}
// Activate the sliders
$('#sliders input').on('input change', function () {
chart.options.chart.options3d[this.id] = this.value;
showValues();
chart.redraw(false);
});
showValues();
});
});
My JSON is formatted like:
[{"key":"Math","value":6},{"key":"Biology","value":"8"},{"key":"English","value":"7"},{"key":"Gym","value":"4"}]
So I would like to have more JSONs like so, in one file to be parsed in the Javascript and be loaded in into the series.
Thank you!
EDIT
thanks for your reply. I have edited my code:
$(function () {
var processed_json = new Array();
var options = {
chart: {
renderTo: 'container',
type: 'column',
options3d: {
enabled: true,
alpha: 0,
beta: 0,
depth: 0,
viewDistance: 25
}
},
title: {
text: 'Grades'
},
subtitle: {
text: 'Dataset'
},
plotOptions: {
column: {
depth: 0
}
},
series: [{
}],
credits: {
enabled: false
}
};
$.getJSON('/uploads/test.json', function(data) {
for (i = 0; i < data.length; i++) {
processed_json.push([data[i].key, data[i].value]);
}
});
options.series[0].remove();
options.series[0].setData = {
name: 'Grades',
data: processed_json
}
var chart = new Highcharts.Chart(options);
chart.redraw(true);
function showValues() {
$('#alpha-value').html(chart.options.chart.options3d.alpha);
$('#beta-value').html(chart.options.chart.options3d.beta);
$('#depth-value').html(chart.options.chart.options3d.depth);
}
// Activate the sliders
$('#sliders input').on('input change', function () {
chart.options.chart.options3d[this.id] = this.value;
showValues();
chart.redraw(false);
});
showValues();
});
But nothing is displayed anymore and the following error is given
TypeError: options.series[0].remove is not a function
I have also tried
var chart = new Highcharts.Chart(options);
chart.series[0].remove();
chart.series[0].setData = {
name: 'Grades',
data: processed_json
}
chart.redraw(true);
But this gives:
TypeError: Cannot set property 'setData' of undefined

I think highcharts has a method chart.addSeries for adding a new series. If you want to replace the current series with a new series, you can try removing first the current series using chart.series[0].remove( ) then add the new series with chart.addSeries. The parameter for the chart.addSeries can be an object like your
{
name: 'Grades',
data: processed_json
}

Then, define method with load data.. example:
function(chart) {
$.each(chart.series, function(i, v){
chart.series[i].remove(true);
});
chart.addSeries({your_data}, true);
}
check http://api.highcharts.com/highcharts/Chart.addSeries/Chart.addSeries
In my webapp, i use 10 of 15 types of graphs highchart and all dynamically load and work fine :) Highcharts is awesome.

csv live data highchart

My data won't display proper.
I have this kind of data: "1456135353.000000|5424492576222277|8156610153681827"
"1456135353" is for the time.
"5424492576222277" is for the first X
"8156610153681827" is for the second X
This is my code:
var chart
/**
* Request data from the server, add it to the graph and set a timeout
* to request again
*/
function requestData () {
$.ajax({
url: 'api/chart',
dataType: 'text',
success: function (point) {
var series = chart.series[0].push
// longer than 20
// add the point
chart.series[0].addPoint(point, true)
// call it again after one second
setTimeout(requestData, 1000)
},
cache: false
})
}
$(document).ready(function () {
chart = new Highcharts.Chart({
chart: {
renderTo: 'container',
defaultSeriesType: 'line',
events: {
load: requestData
}
},
title: {
text: 'XSnews Graph'
},
xAxis: {
type: 'datetime',
tickPixelInterval: 150,
maxZoom: 20 * 1000
},
yAxis: {
gridLineColor: '#197F07',
gridLineWidth: 1,
title: {
text: 'GB',
margin: 80
}
},
series: [{
name: 'Time',
data: []
}]
})
})
I am not familiar with Highcharts so I have no clue what I am doing wrong.
Do I need to parse it?

You need to parse your data first, before adding a point. Something like this:
success: function (point) {
var options = point.split("|"),
x = parseFloat(options[0]) * 1000,
y_1 = parseFloat(options[1]),
y_2 = parseFloat(options[2]);
chart.series[0].addPoint([x, y_1], true);
setTimeout(requestData, 1000)'
}

Highcharts bar chart wont animate

Not sure why because I have done it in the past, but I have a Highcharts bar chart and it won't animate. This is the declaration of the chart,
function initializeData() {
$http.get(url).success(function(ret) {
$scope.jsondata = ret;
var newdata = [];
for (x = 0; x < 5; x++) {
newdata.push({
name: setName($scope.jsondata[x].name),
y: $scope.jsondata[x].data[0],
color: getColor($scope.jsondata[x].data[0])
});
}
$scope.chart.series[0].setData(newdata);
});
mainInterval = $interval(updateData, 5000);
}
function updateData() {
$http.get(url).success(function(ret) {
$scope.jsondata = ret;
console.debug("here");
for (x = 0; x < 5; x++) {
$scope.chart.series[0].data[x].update({
y: $scope.jsondata[x].data[0],
color: getColor($scope.jsondata[x].data[0])
});
}
});
}
$scope.chart = new Highcharts.Chart({
chart: {
renderTo: 'container',
type: 'bar',
animation: true,
events: {
load: initializeData
}
},
title: {
text: ''
},
xAxis: {
type: 'category',
labels: {
style: {
fontSize: '11px'
}
}
},
yAxis: {
min: 0,
max: 100,
title: {
text: 'Total Score',
align: 'high'
}
},
legend: {
enabled: false
},
tooltip: {
pointFormat: 'Total Score <b>{point.y:.3f}</b>'
},
series: [{
name: 'Active Users',
data: [],
dataLabels: {
enabled: true,
rotation: 30,
style: {
fontSize: '10px',
fontFamily: 'Verdana, sans-serif'
},
format: '{point.y:.3f}', // one decimal
}
}]
});
And as you can see I have animate : true, so I am not sure what is the problem here. I have this older plunker where all of the data is in separate series, but it animates fine. But this is the plunker I am working on and having trouble with. They are like identical basically. In the newer one I broke out the initialization of data into its own method, but that is the only real main difference.
Some edits:
So as I was saying, I have done things this way with an areaspline chart (I know it was said they work a bit different but they are set up identically).
function initializeData() {
$interval.cancel(mainInterval);
$scope.previousPackets = '';
$http.get("https://api.myjson.com/bins/nodx").success(function(returnedData) {
var newdata = [];
var x = (new Date()).getTime();
for (var step = 9; step >= 0; step--) {
newdata.push([x - 1000 * step, 0]);
}
$scope.chart.series[0].setData(newdata);
});
mainInterval = $interval(updateData, 2000);
}
function updateData() {
$http.get(url + acronym + '/latest').success(function(returnedData) {
var x = (new Date()).getTime();
if ($scope.previousPackets != returnedData[0].numPackets) {
$scope.chart.series[0].addPoint([x, returnedData[0].numPackets], true, true);
$scope.previousPackets = returnedData[0].numPackets;
} else {
$scope.chart.series[0].addPoint([x, 0], true, true);
}
});
}
$scope.chart = new Highcharts.Chart({
chart: {
renderTo: 'container',
type: 'areaspline',
animation: Highcharts.svg, // don't animate in old IE
marginRight: 10,
events: {
load: initializeData
}
},
title: {
text: ''
},
xAxis: {
type: 'datetime',
tickPixelInterval: 150
},
yAxis: {
title: {
text: 'Packets'
},
plotLines: [{
value: 0,
width: 1,
color: '#d9534f'
}]
},
tooltip: {
formatter: function() {
return Highcharts.numberFormat(this.y) + ' packets<b> | </b>' + Highcharts.dateFormat('%H:%M:%S', this.x);
}
},
legend: {
enabled: false
},
exporting: {
enabled: false
},
series: [{
name: 'Packets',
data: []
}]
});
I also updated the first chunk of code with the initializeData() method and updateData() method which are seemingly identical in both different charts.

It looks like it plays an important role if you provide your data at chart initialization or after. For simplicity I refactored your code a little
function initializeChart(initialData, onload) {
$scope.chart = new Highcharts.Chart({
chart: {
renderTo: 'container',
type: 'bar',
animation: true,
events: {
load: onload
}
....
series: [{
name: 'Active Users',
data: initialData,
dataLabels: {
enabled: true,
format: '{point.y:.3f}', // one decimal
}
}]
});
}
function getData(callback) {
$http.get(url).success(function(ret) {
$scope.jsondata = ret;
var newdata = [];
for (x = 0; x < 5; x++) {
newdata.push([setName(ret[x].name), ret[x].data]);
}
callback(newdata);
});
}
As a result your two planks are in essense reduced to two methods below. The first initializes chart with preloaded data and the second updates data in existing chart.
function readDataFirst() {
getData(function(newdata) {
initializeChart(newdata);
});
}
function initializeChartFirst() {
initializeChart([], function() {
getData(function(newdata) {
$scope.chart.series[0].setData(newdata);
})
});
}
The first one animates fine while the second does not. It looks like highcharts skips animation if dataset is not initial and is treated incompatible.
However if you really want to have animation in your current plant (chart first workflow) you can achieve that by initializing first serie with zeros and then with the real data. This case it will be treated as update
function forceAnimationByDoubleInitialization() {
getData(function(newdata) {
initializeChart([]);
var zerodata = newdata.map(function(item) {
return [item[0], 0]
});
$scope.chart.series[0].setData(zerodata);
$scope.chart.series[0].setData(newdata);
});

highcharts with only javascript and no jquery

So without jquery I want to update highcharts with new data live. I have a chart that displays data from a database, and I am doing a http get request to get the data every few seconds. I am able to grab the data correctly, but when I push the new data onto the series variable for the chart, the graph doesn't update in real time. It only updates when I refresh. How can I fix this? I am using highcharts in angularjs.

you should call series.addPoint() instead of just updating the data array

please see here http://jsfiddle.net/9m3fg/1
js:
var myapp = angular.module('myapp', ["highcharts-ng"]);
myapp.controller('myctrl', function ($scope) {
$scope.addPoints = function () {
var seriesArray = $scope.chartConfig.series
var newValue = Math.floor((Math.random() * 10) + 1);
$scope.chartConfig.xAxis.currentMax++;
//if you've got one series push new value to that series
seriesArray[0].data.push(newValue);
};
$scope.chartConfig = {
options: {
chart: {
type: 'line',
zoomType: 'x'
}
},
series: [{
data: [10, 15, 12, 8, 7, 1, 1, 19, 15, 10]
}],
title: {
text: 'Hello'
},
xAxis: {
currentMin: 0,
currentMax: 10,
minRange: 1
},
loading: false
}
});

From your code it looks like you want to add new series rather then new data if yes please see here: http://jsfiddle.net/bYx4a/
var app = angular.module('app', ["highcharts-ng"]);
app.controller("myCtrl", ['$scope', '$http', function ($scope, $http) {
var count = 0;
$scope.chartOptions = {
chart: {
type: 'line'
},
title: {
text: 'Fruit Consumption'
},
xAxis: {
categories: ['Apples', 'Bananas', 'Oranges']
},
yAxis: {
title: {
text: 'Fruit eaten'
}
},
series: [{
name: 'Jane',
data: [1, 0, 4]
}]
};
$scope.addSeries = function () {
var newData = {
name: 'John',
data: [1, 4, 3]
};
$scope.chartOptions.series.push({
name: newData.name,
data: newData.data
})
};
}]);

Here is my solution for using Highcharts addPoint function in the highcharts-ng directive:
$scope.chart_realtimeForceConfig = {
options: {
chart: {
type: 'line',
},
plotOptions: {
series: {
animation: false
},
},
},
series: [
{
name: 'Fx',
data: []
},
],
func: function(chart) {
$timeout(function() {
chart.reflow();
$scope.highchart = chart;
}, 300);
socket.on('ati_sensordata', function(data) {
if (data) {
var splited = data.split('|');
if (splited.length >= 6) {
var val = parseFloat(splited[5]);
var shift = chart.series[0].data.length > 100;
chart.series[0].addPoint(val, true, shift, false);
}
}
});
},
loading: false
}

How to add multiple series dynamically and update its data dynamically

my task is to add series dynamically and keep updating their data, which is received by ajax calls.
i know series can be added dynamically by declaring highchart funciton global. and using series.addseries() function , and also data can be updated by using settimout request to ajax call and updating points by using series.addpoint() function.
i have done both the work separably. but when i combine both the technique, data is not added to highchart. i have done lot of research on this, and i am not finding reason for not adding the data. infact script hang the browser.
i have checked the series object, which show x-data and y-data are processed. only difference i find is isDirty field and isDirtydata field are set to true. dont know the reason.
here is the full code
var serverUrl = 'http://'+window.location.hostname+':8000'
Highcharts.setOptions({

i am stuck on this problem for quite a while. and still not able to figure out the solution.
here is the full code link
someone please please help. feeling frustrated ..:-(

As you know the addPoint method is bit dangerous when dealing with quite lots points. It is recommended to disable redraw per point when dealing with many new points - more info http://api.highcharts.com/highcharts#Series.addPoint() , I notice you are doing that already in the loop statement, but why did you commented out? have you tried enabling again. Make sure chart.redraw works by adding a new redraw chart event, and set an alert or console log.
Also you may try using, below as part of ajax, instead of cache:false. I had some problems in past.
headers: { 'Cache-Control': 'no-cache' }
Cheers
