I have this angular module I am using for a widget that displays a Highcharts chart, but for some reason it isn't displaying. I have the module name and the controller name but declared in the html, but I guess I am missing something?
angular.module('myapp', ['cgOwf'])
.controller('mainctrl', function($scope, $element, $attrs, $http, $interval, owf) {
$scope.jsondata = [];
var mainInterval = '';
$scope.username = '';
owf.ready(function() {
owf.Eventing.subscribe('traffic-channel', function(sender, msg, channel) {
console.debug("Got " + msg + " inside of owf ready");
$scope.username = msg;
console.log($scope.username);
//-----------------------------------------------
$scope.chart = new Highcharts.Chart({
chart: {
renderTo: 'container',
type: 'areaspline',
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() * .5;
series.addPoint([x, y], true, true);
}, 5000);
}
}
},
title: {
text: ''
},
xAxis: {
type: 'datetime',
tickPixelInterval: 150
},
yAxis: {
title: {
text: 'Value'
},
plotLines: [{
value: 0,
width: 1,
color: '#d9534f'
}]
},
tooltip: {
formatter: function() {
return '<b>' + this.series.name + '</b><br/>' +
Highcharts.dateFormat('%Y-%m-%d %H:%M:%S', this.x) + '<br/>' +
Highcharts.numberFormat(this.y, 2);
}
},
legend: {
enabled: false
},
exporting: {
enabled: false
},
credits: {
enabled: false
},
series: [{
name: 'Random data',
data: (function() {
// generate an array of random data
var data = [],
time = (new Date()).getTime(),
i;
for (i = -10; i <= 0; i += 1) {
data.push({
x: time + i * 1000,
y: Math.random() * .2
});
}
return data;
}())
}]
});
});
});
}
}));
From the //--------------------------- down it is really just setting up the chart, so i guess the part in question is above that. Here is the html, but this should be right because I've done this a few times:
<body ng-app="myapp" ng-controller="mainctrl">
<div id="wrapper">
<div style="margin: 1em">
<h4>Traffic <span ng-show="username"> for {{username}}</span></h4>
<div id="container" class="barchart" style="min-width: 310px; height: 400px; margin: 0 auto"></div>
</div>
</div>

In highcharts, when I add data using addpoint() allowing 'shift' to 'true', the tool-tip does not move when it has large data just like how it moves when it has low data. the amount of data can be recognised by changing range of rangeSelector. Is there anything I can modify or should I include some extra code. I have reproduced the issue in below link.
https://jsfiddle.net/1y3gmkt5/
// Create the chart
Highcharts.stockChart('container', {
chart: {
events: {
load: function () {
// set up the updating of the chart each second
var series1 = this.series[0];
setInterval(function () {
var x = (new Date()).getTime(), // current time
y = Math.round(Math.random() * 100);
series1.addPoint([x, y], true, true);
}, 2000);
var series2 = this.series[1];
setInterval(function () {
var x = (new Date()).getTime(), // current time
y = Math.round(Math.random() * 50);
series2.addPoint([x, y], true, true);
}, 2000);
}
}

expected result: when mouse pointer is hovered over any marker and left as it is, then tool-tip should move behind as and when new data arrives. Currently works fine when range selector has low data but not when there is large data.
The issue is caused by dataGrouping property that modifies the data. You can disable it by:
plotOptions: {
series: {
dataGrouping: {
enabled: false
},
...
}

I have this example code where I wanna update my chart every time on event "onmessage" but it doesnt update the chart.
A console.log() shows me that the callback is executed with the right values but nothing appears in the chart.

JavaScript Part:
setting the options....
$(document).ready(function () {
Highcharts.setOptions({
global: {
useUTC: false
},
plotOptions: {
series: {
turboThreshold: 0 // 0 to disable https://api.highcharts.com/highcharts/plotOptions.series.turboThreshold
}
}
});
creating the chart with a timespan of 1 hour:
var chart = Highcharts.chart('container', {
chart: {
type: 'spline',
animation: Highcharts.svg, // don't animate in old IE
marginRight: 10
},
title: {
text: 'Live Test.sensor.val'

data: (function () {
// generate an array of random data
var data = [],
time = (new Date()).getTime(),
i;
for (i = -60 * 60; i <= 0; i += 1) { //defines the visible timespan on x axis
data.push({
x: time + i * 1000,
y: null
});
}
return data;
}())
}]
});
here I am hoping to get the values into the chart but it is not working...
Just the console.log() shows me the values but nothing is updated in the chart.
var ev = new EventSource("/incommingEventHandler.ashx");
ev.onmessage = function (e) {
var dat = e.data;
var x = (new Date()).getTime(), // current time
y = dat;
console.log(x, y); //showing values correctly but no update on chart? Why?
chart.series[0].addPoint([x, y], true, true);
};
});
Thanks Dieter
it was my fault.
Server sent events seams to be transmitted as strings.
Therefore my value from e.data is from type string.
I casted it via parseFloat(y) and everything is working fine now.
I have a similar requirement and created a fiddle
I am trying to make use of tickPositions to set the xAxis ticks but the problem is the ticks are moving out of the chart window. Can, any one please help me with this. Also, please let me know if I am doing something wrong.

The JavaScript console is saying undefined function. When I put the highstock script above the exporting script, as in the jsfiddle you linked, it works fine.
The problem is that you refer to serie OHLC which is supported only in Highstock. So you need to attach highstock.js
I'm new in Laravel, so I'm still facing problems whenever I try to add js functions to my code.
I need to add a highchart to my laravel project. As a beginning, I just copied the code of one of the charts available on highcharts.com and pasted it in the main view, but nothing is being displayed.
When I added the same code to a normal html file, the graph was displayed normally.
Here's my javascript code
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.8.2/jquery.min.js"></script>
<script src="http://code.highcharts.com/highcharts.js"></script>
<script type="text/javascript">
$(function () {
$(document).ready(function () {
Highcharts.setOptions({
global: {
useUTC: false
}
});
$('#container').highcharts({
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);
}
}
},
title: {
text: 'Live random data'
},
xAxis: {
type: 'datetime',
tickPixelInterval: 150
},
yAxis: {
title: {
text: 'Value'
},
plotLines: [{
value: 0,
width: 1,
color: '#808080'
}]
},
tooltip: {
formatter: function () {
return '<b>' + this.series.name + '</b><br/>' +
Highcharts.dateFormat('%Y-%m-%d %H:%M:%S', this.x) + '<br/>' +
Highcharts.numberFormat(this.y, 2);
}
},
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;
}())
}]
});
});
});
</script>
and the html code
<div id="container" style="width:100%; height:400px;"></div>
Any suggestions how to display the graph?
Thanks in advance.
I think the problem is with the syntax you are creating the chart with: $('#container').highcharts...
It seems highcharts function is not defined using laravel.
There is another way that you can try:
var chart = new Highcharts.Chart({
chart: {
renderTo: 'container',
...
},
...
});
