Display 100 Points in 1 second : Highcharts

So I have a project where I am trying to update chart. in which 100 points to be displayed in each second.
For that I am trying this example from the Highcharts.
But the chart stops responding to such event.
The code:
jsfiddle
Highcharts.chart('container', {
chart: {
type: 'spline',
animation: Highcharts.svg, // don't animate in old IE
marginRight: 10,
events: {
load: function () {
// set up the updating of the chart each second
var series = this.series[0];
setInterval(function () {
var x = (new Date()).getTime(), // current time
y = Math.random();
series.addPoint([x, y], true, true);
}, 10);
}
}
},
time: {
useUTC: false
},
title: {
text: 'Live random data'
},
xAxis: {
type: 'datetime',
tickPixelInterval: 150
},
yAxis: {
title: {
text: 'Value'
},
plotLines: [{
value: 0,
width: 1,
color: '#808080'
}]
},
tooltip: {
headerFormat: '<b>{series.name}</b><br/>',
pointFormat: '{point.x:%Y-%m-%d %H:%M:%S}<br/>{point.y:.2f}'
},
legend: {
enabled: false
},
exporting: {
enabled: false
},
series: [{
name: 'Random data',
data: (function () {
// generate an array of random data
var data = [],
time = (new Date()).getTime(),
i;
for (i = -19; i <= 0; i += 1) {
data.push({
x: time + i * 1000,
y: Math.random()
});
}
return data;
}())
}]
});

You can set redraw parameter in addPoint method to false and call chart.redraw() at longer intervals:
chart: {
...,
events: {
load: function() {
// set up the updating of the chart each second
var series = this.series[0],
chart = this;
setInterval(function() {
var x = (new Date()).getTime(), // current time
y = Math.random();
series.addPoint([x, y], false, true);
}, 10);
setInterval(function() {
chart.redraw();
}, 500);
}
}
}

Spline Graph with diagonally fixed values with 0,0 and ploting remaing same

We are using Spline Graph for our game in which we are facing issue with x and y axis value which we need to put 0,0 and save the values from initially till end as we need to all plotting from start till end of the value.

JavaScript Code
<script>
var a = 1;
var b = 1;
var factor = 1.2;
$(document).ready(function () {
Highcharts.chart('container', {
chart: {
type: 'spline',
animation: Highcharts.svg, // don't animate in old IE
marginRight: 10,
events: {
load: function () {
// set up the updating of the chart each second
var series = this.series[0];
setInterval(function () {
b = b*1.2;
console.log(b);
var x = a; // current time
var y = b;
a++;
series.addPoint([x, y], true, true);
}, 700);
}
}
},
title: {
text: 'Live random data'
},
xAxis: {
type: 'number',
min: 0,
tickInterval: 2
},
yAxis: {
title: {
text: 'Value'
},
plotLines: [{
value: 0,
width: 1,
color: '#808080'
}]
},
tooltip: {
formatter: function () {
return '<b>X: ' + this.x+', Y:'+this.y;
}
},
legend: {
enabled: false
},
exporting: {
enabled: false
},
series: [{
name: 'Random data',
data: (function () {
// generate an array of random data
var data = [],i;
for (i = 1; i <= 19; i++) {
b = b*factor;
data.push({
x: a,
y: b
});
a++;
}
return data;
}())
}]
});
});

The following code draws a curve line from the origin (0,0) to the end point which gets updated on the interval. You needed to make the shift variable false in the addPoint call. Higchart docs
$(document).ready(function () {
var a = 1;
var b = 1;
var factor = 1.2;
Highcharts.chart('container', {
chart: {
type: 'spline',
animation: Highcharts.svg, // don't animate in old IE
marginRight: 10,
events: {
load: function () {
// set up the updating of the chart each second
var series = this.series[0];
setInterval(function () {
b = b*1.2;
var x = a; // current time
var y = b;
a++;
// Add new end point
series.addPoint([x, y], true, false);
}, 700);
}
}
},
title: {
text: 'Live random data'
},
xAxis: {
type: 'number',
min: 0,
tickInterval: 2
},
yAxis: {
title: {
text: 'Value'
},
plotLines: [{
value: 0,
width: 1,

}]
},
tooltip: {
formatter: function () {
return '<b>X: ' + this.x+', Y:'+this.y;
}
},
legend: {
enabled: false
},
exporting: {
enabled: false
},
series: [{
name: 'Random data',
data: (function () {
// generate an array of random data
// Add point at origin and last point of series
var data = [{x:0,y:0}],i;
for (i = 1; i <= 19; i++) {
b = b*factor;
a++
data.push({
x: a,
y: b
});
}
return data;
}())
}]
});
});

How to update Highcharts data dynamically over a period of time

I want to use Highcharts graph and update y axis dynamically. Actually I want to update nsw, Tas, ACT every 5 sec. How do I do it ?
Here is my code.
$(function () {
$('#container').highcharts({
title: {
text: 'Histogram',
x: -20 // center
},
subtitle: {
text: 'Source: www.trove.com',
x: -20
},
xAxis: {
categories: ['NSW', 'Tas', 'ACT','QLD','VIC','SA','WA']
},
yAxis: {
title: {
text: 'Hits'
},
plotLines: [{
value: 0,
width: 1,
color: '#808080'
}]
},
tooltip: {
valueSuffix: '°C'
},
legend: {
layout: 'vertical',
align: 'right',
verticalAlign: 'middle',
borderWidth: 0
},
series: [{
name: 'States',
data: [nsw, Tas, ACT,qld,vic,sa,wa]
}]
});
});
});

In the Documentation you can find an example from Highcharts in jsfiddle. Check it out http://jsfiddle.net/gh/get/jquery/1.9.1/highslide-software/highcharts.com/tree/master/samples/highcharts/demo/dynamic-update/. In the example every second a new point will be added. Here comes the relevant code part:
chart: {
type: 'spline',
animation: Highcharts.svg, // don't animate in old IE
marginRight: 10,
events: {
load: function () {
// set up the updating of the chart each second
var series = this.series[0];
setInterval(function () {
var x = (new Date()).getTime(), // current time
y = Math.random();
series.addPoint([x, y], true, true);
}, 1000);
}
}
},
`

The easiest way to do it would be to use the javascript function "setInterval()" to call it.
Here is a link where you can find a way to do it :
http://www.w3schools.com/js/js_timing.asp
If you are not really good at javascript, you might need this declaration of functions : var functionName = function() {} vs function functionName() {}

Use:
events: {
load: function () {
// set up the updating of the chart each second
var series = this.series[0];
setInterval(function () {
var x = (new Date()).getTime(), // current time
y = Math.random(),
l = series.data.length;
for(var i = 0; i < l; i++) {
series.data[i].update({
y: getHits(i) // or something else
});
}
}, 5000); // 5 seconds
}
}
Where index is index (count from 0) of nsw/Tas/ACT in data array. (for nsw = 0, for Tas = 1 etc.)

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' }

addPoint using highcharts (javascript)

I have started working with highcharts.js, but fails to add new points my bar graph:
Every time it goes into addPoint, Firefox freezes :(
I am using Firebug, and when it tries to addPoint, it always freeze :(
// if no graph
if (! charts[0])

total_bets.push(Number(value[3]));
