Shows a single chart on Highcharts

Hello I'm having a problem with my code in Highcharts I already declared my series but it only shows 1 set of chart. All data were set on var dataStr, on how the data that being put, I use push on every data that is being passed. So I think the problem is the with my push?
var dataStr = [
{name: 'JOB-182', problemReportCount: 0, totalCost: 50000, lostHour: 0, lostValue: 0},
{name: 'JOB-185', problemReportCount: 0, totalCost: 3432.65, lostHour: 0, lostValue: 0},
{name: 'JOB-188', problemReportCount: 4, totalCost: 5000, lostHour: 0, lostValue: 0},
{name: 'JOB-189', problemReportCount: 0, totalCost: 1000, lostHour: 0, lostValue: 0}
];
var jRefs = [];
var prJRefs = [];
var prLostVals = [];
var prLostHours = [];
var totCosts = [];
for (var i = 0; i < dataStr.length; i++) {
var jName = '' + dataStr[i].name;
if (jName != '') {
jRefs.push(jName);
var prCount = dataStr[i].problemReportCount;
if (prCount > 0) {
prJRefs.push(jName);
prLostVals.push(dataStr[i].lostValue);
prLostHours.push(dataStr[i].lostHour);
totCosts.push(dataStr[i].totalCost);
}
}
}
var genGraph = function() {
$("#backButton").hide();
$('#prGraph4').highcharts({
chart: {
type: 'column',
plotBackgroundColor: '#F7F7F7'
},
title: {
text: 'Problem Report'
},
subtitle: {
text: 'Estimated Lost Values'
},
xAxis: {
alternateGridColor: '#fff',
categories: prJRefs
},
yAxis: {
min: 0,
title: {
text: 'Amount'
},
stackLabels: {
enabled: true,
style: {
fontWeight: 'bold'
}
}
},
plotOptions: {
column: {
stacking: 'normal',
}
},
tooltip: {
shared: true,
formatter: function() {
var s = '<b>' + this.x + '</b>';
$.each(this.points, function() {
var lostValue = this.y;
s += '<br/><span style=" + dbl + "color:' + this.series.color + ';" + dbl + ">\u25CF</span> ' + this.series.name + ': <b>£</b> ' + lostValue.toFixed(2);
});
return s;
}
},
series:[{
name: 'Total Costs',
data: totCosts,
color: '#2ecc71',
stack: 'total'
}, {
name: 'Estimated Lost Materials Value',
data: prLostVals,
color: '#e74c3c',
stack: 'lost'
}, {
name: 'Estimated Lost Hours Price',
data: prLostHours,
color: '#e67e22',
stack: 'lost'
}]
});
};
Any help would be so much appreciated. Thanks!

You have only one visible column because only one set of data fulfills this condition:
if (prCount > 0) {
prJRefs.push(jName);
prLostVals.push(dataStr[i].lostValue);
prLostHours.push(dataStr[i].lostHour);
totCosts.push(dataStr[i].totalCost);
}
In addition, all values from series: Estimated Lost Materials Value and Estimated Lost Hours Price are 0.

In Graph2d sometimes points are not connected

I'm using vis.js v. 4.12.0. I've noticed that sometimes using Graph2d some points are not connected.
.
I think this behaviour depends on points distance; does someone knows how to force points connection?

#selten98: Sure, here my code:

Javascript Heavy Scripting Load(Lags the website)

I have the website that runs on javascript 1.7.1 and everytime i click a button that runs the Javascript method, the web load becomes far more heavier and continuously run the javascript up to the point that the site starts to lag.Here is an example of my JS method:
function makeGraph() {

I also have run a developer tool in IE 11 which shows me that it is indeed from the nonstop javascript loop. I was wondering if anyone could help me stop the JS loop so that it is not continuous.(I am also using SignalR and i dont know if this is one of the factors).Thanks in advance.
These are the header tags:

and yes, I am using highchart.js in this function and the button is that so i can refresh and sort the graph according to the buttons i clicked which in these cases are categories of cities.

how to integrate the data from yahoo finance with php/ajax/graph.js

I have a code of euro-dollar exchange via YAHOO FINANCE works with PHP / AJAX. My question is how to integrate the data released chart works with CHARTS.JS
I would like to get this result
labels: ["2016-06-02 12:41:06", "2016-06-02 12:41:08"],
datasets: [{
label: "My Third dataset - No bezier",
data: [1.1200,1.1205],
lineTension: 0,
fill: false,
}]
The result:
{"rate":"1.1200","time":"2016-06-02 12:41:06"}
{"rate":"1.1205","time":"2016-06-02 12:41:08"}
{"rate":"1.1199","time":"2016-06-02 12:41:10"}

Highcharts Line Charts Out of memory

I am trying to populate a line chart using Highcharts. It was working great until a couple of days ago, then it started crashing Chrome and Internet Explorer gives the "SCRIPT7: Out of memory" error. I have 3 other line charts built the exact same way, that work fine. This chart works great as a column chart.
Here is the JSFIDDLE. Code below:
function average(arr) {
return _.reduce(arr, function(memo, num) {
var total = memo + num;
return memo + num;
}, 0) / (arr.length === 0 ? 1 : arr.length);
}
function translateMonth(d) {
var month;
if (d.getMonth() === 0) {
month = 'Jan';
} else if (d.getMonth() === 1) {
month = 'Feb';
} else if (d.getMonth() === 2) {
month = 'Mar';
} else if (d.getMonth() === 3) {
month = 'Apr';
} else if (d.getMonth() === 4) {
month = 'May';
} else if (d.getMonth() === 5) {

The particular data for this chart brings out an error in your code. You have an endless loop in your yAxis.tickPositioner function. You have this code:
increment = Math.ceil((this.dataMax - this.dataMin) / 6);
for (tick; tick - increment <= this.dataMax; tick += increment) {
// ...
}
In short, your increment value becomes 0 if the min and max value of the data is the same, and therefore your for loop statement tick += increment does nothing, and it keeps going forever.
This can be fixed by assuring your increment value is a minimum of 1. You could try (JSFiddle):
increment = Math.max(1, Math.ceil((this.dataMax - this.dataMin) / 6));
