highcharts (using csv data) not loading until refreshing the page, sometimes i even have to refresh several times

I'm using html, css and javascript for the project. The server is set up locally including node, express and highcharts.
In my html i have a div container, that i'm referencing in my highcharts function. The data i'm using in the highchart come from a csv file. I wrote a simple getData function, that parses the data into an array. And at the top of the highchartsfunction, i'm using await getData, so the chart can only be rendered after getting the data for it. All functions are async. On that one page i'm having seven charts, all constructed using the syntax following below, each with its own getData function and div container.
Two problems:
Problem No.1:
The charts are not getting displayed until i refresh the page and often times i even have to refresh it several times, till every chart is getting shown at a time (Like 20 times). The functions are all executed, i checked that in the console.
Problem No.2:
I would like to write this dynamically, as i want to have multiple pages on my website, each using its own csv file, but basically the same code.
*Edit:
From time to time i receive: "Error: Highcharts error #13: www.highcharts.com/errors/13/" in the console, but as i keep refreshing it changes the line/js it is referencing to. It always is the part of the highcharts function, in which i give it its container Highcharts.chart('hammerchart', {. I checked this error and what it sais is basically, that the script can't find a container with the #id. Which i don't understand as im using "DOMContentLoaded". I tried the "load" event instead, which solved the error #13, but ended up in no chart getting displayed at all without any error message.
*Edit2:
Until now i only used firefox to view my website. I checked Chrome aswell and here i don't have any error message, but it also never shows any of the charts aswell at all.
If someone could help me out here, i would be really happy, as i tried to fix this for days now with no success. I'm also open for suggestions, regarding the handling of my data. Thank you veeeery much in advance!!

Javascript - first declaration of the arrays, then my parsing function, splitting the csv by linebreaks and commas. Then i'm using parseFloat(), so that i don't have strings in it. In the highcharts function i'm using await getData and DOMContentloaded, to make sure both html and my data are ready.

const columnthrees = [];
const columnfours = [];
const columnfives = [];

const data = await response.text();
const table = data.split('\n');
table.forEach(row => {
const columns = row.split(',');
const year = columns[0];
years.push(year);
const columntwo = columns[1];
columntwos.push(parseFloat(columntwo));

Highcharts Map not rendering no errors

I am attempting to take the example produced by Highcharts here http://www.highcharts.com/maps/demo/color-axis and substitute the data loaded by the $.getJson with a local JSON file called 'testdata1.json'.
The code I've modified below produces no errors yet the map does not render. I think it's because the testdata1.json is loaded late, after the javascript is executed. If so, is there a better way I should be doing this -- perhaps waiting for the data to load before executing the JS file? I attempted to do this by placing a
$(document).ready(
in front of the function but it didn't work. Any thoughts are greatly appreciated, I think it's something relatively minor that is just escaping me.
Thank you.

You have three problems. Here's a fiddle based on their sample that uses your approach, but still uses their data, and works: http://jsfiddle.net/g29k24vw/1/
Here are the important parts:
chart : {
renderTo: 'container',
borderWidth : 1,
type: 'map'
},
And:
$.getJSON('http://www.highcharts.com/samples/data/jsonp.php?filename=us-population-density.json&callback=?', function (data) {
// Make codes uppercase to match the map data
$.each(data, function () {
this.code = this.code.toUpperCase();
});
options.series[0].data= data;
var chart = new Highcharts.Chart(options);
});
Note the differences here:
You need to specify the chart type in options if you're going to instantiate the chart object directly instead of using the jQuery helper.
renderTo doesn't want a hash in front of the element name.
options.series[0].data, not options.series.data...series is actually an array of objects.

How to zoom to specific point in Highmaps

Highmaps / highcharts is a javascript/jquery adapter that renders maps in browsers etc.
I have a map with a single country highlighted, however, the scale of the (world) map is such that I want zoom in after the map is loaded on the country in question.
Looking at the API I feel certain this is possible.
There is an event listener, such that I can execute custom functions on load. As illustrated with this example, where a series is added on load (Js fiddle)
Additionally there is a method mapZoom allowing you to specify a point to zoom to with the following arguments:
mapZoom (Number howMuch, [Number centerX], [Number centerY], [Number mouseX], [Number mouseY])
But when I try and call this method onload (my code attempt below, JS fiddle here), nothing happens.
$(function () {
$.getJSON('http://www.highcharts.com/samples/data/jsonp.php?filename=world-population-density.json&callback=?', function (data) {
// Assign id's
$.each(data, function () {
this.id = this.code;
});
// Initiate the chart
$('#container').highcharts('Map', {
chart: {
events: {
load: function () {
mapZoom(0.5, 100, 100);
}
}
},
title: {
text: 'Zoom on load attempt'
},
legend: {
title: {
text: 'Population density per km²'
}
},
colorAxis: {
min: 1,
max: 1000,
type: 'logarithmic'
},
mapNavigation: {
enabled: true,
buttonOptions: {
verticalAlign: 'bottom'
}
},
series : [{
data : data,
mapData: Highcharts.maps['custom/world-highres'],
joinBy: ['iso-a2', 'code'],
name: 'Population density',
allowPointSelect: true,
cursor: 'pointer',
states: {
hover: {
color: '#BADA55'
}
},
tooltip: {
pointFormat: '{point.id} {point.name}',
valueSuffix: '/km²'
}
}]
});
});
});

mapZoom is a method that belongs to the chart object so, in order to call it as en event (load), you have to call it using this keyword.
You can edit your code like this (JSFiddle):
...
events: {
load: function () {
this.mapZoom(0.5, 100, 100);
}
}
}
...
Alternatively, you can call it whenever you want using a jQuery reference (JSFiddle):
$('#container').highcharts().mapZoom(0.5, 100, 100);

Zoom to a specific country on your map is easy
series : [{
...
data: [{code: 'HU', id: 'HU', value: 7.5, name: 'Hungary'}],
...
}
...and then...
var mapChart=$('#MapContainer').highcharts(); //get map chart object from DOM
mapChart.get('HU').zoomTo(); //zoom to the country using "id" from data serie
mapChart.mapZoom(5); //elevate viewpoint a little to see surrounding countries as well

If you want to zoom several countries, than you can try this
events: {
load: function () {
var mapChart = this;
['DE', 'HU', 'RO'].map(function(code){
return mapChart.get(code);
}).reduce(function(acc, current){
// Set map bounds
acc._minX = isNaN(acc._minX) ? current._minX : Math.min(acc._minX, current._minX);
acc._maxX = isNaN(acc._maxX) ? current._maxX : Math.max(acc._maxX, current._maxX);
acc._minY = isNaN(acc._minY) ? current._minY : Math.min(acc._minY, current._minY);
acc._maxY = isNaN(acc._maxY) ? current._maxY : Math.max(acc._maxY, current._maxY);
return acc;
}).zoomTo();
}}

Data and tooltip not working for graph using highcharts

I am trying to get a basic column chart working where I will trend for maphours(y-axis), reducehours(y-axis) for a particular job(tooltip) on a particular day(x-axis).
I am populating the data array with y-axis values and jobname value which I want to show in the tooltip. The x-axis value is a datestamp(a daily value i.e one date throughout the x-axis).
Problem - The graph container is getting initiated but it is not picking up the y-axis values and tooltip.
The code where i am populating the arrays -
var obj = data;
var jobSummaryMappersPT = [];
var jobSummaryReducersPT = [];
var jobSummaryMappersDB = [];
var jobSummaryReducersDB = [];
var datestamp = [];
for(i=0;i<obj.length-1;i++){
if(obj[i].grid=='PT'){
jobSummaryMappersPT.push({mappers: obj[i].maphours, jobname: obj[i].jobname}); // Filling of Array after Ajax Call
jobSummaryReducersPT.push({reducers: obj[i].reducehours, jobname: obj[i].jobname}); //Filling of Array
datestamp.push(obj[i].date.replace('T00:00:00.000Z', ' '));
}else{
jobSummaryMappersDB.push({mappers: obj[i].maphours, jobname: obj[i].jobname}); // Filling of Array after Ajax Call
jobSummaryReducersDB.push({reducers: obj[i].reducehours, jobname: obj[i].jobname}); //Filling of Array
}
}
job_summary_chart(jobSummaryMappersPT, jobSummaryReducersPT, jobSummaryMappersDB, jobSummaryReducersDB, datestamp);
The function where I am initiating my Highcharts -
function job_summary_chart(jobSummaryMappersPT, jobSummaryReducersPT, jobSummaryMappersDB, jobSummaryReducersDB, datestamp){
$(function () {
$('#job_summary_pt').highcharts({
// Other Highchart Properties
chart: {
type: 'column'
},
title: {
text: 'Job Summary',
x: -20 //center
},
subtitle: {
text: 'Source: DFTBA',
x: -20
},
xAxis: {
categories: datestamp,
labels: {
rotation: -45,
y: 30,
align: 'center',
step: 4
}
},
yAxis: {
title: {
text: 'GbHrs'
},
plotLines: [{
value: 0,
width: 1,
color: '#808080'
}]
},
tooltip: {
valueSuffix: ' GbHrs',
formatter: function() { return ' ' +
'Jobname: ' + this.point.jobname + '<br />'
}
},
legend: {
layout: 'vertical',
align: 'right',
verticalAlign: 'middle',
borderWidth: 0
},
series: [{
data: jobSummaryMappersPT
},{
data: jobSummaryReducersPT
}]
});
i did a console.log on jobSummaryMappersPT and the values are as follows:
[Object { mappers=97, jobname="abcd.pig"},
Object { mappers=33, jobname="abcd.pig"},
Object { mappers=31, jobname="abcd.pig"},
Object { mappers=15, jobname="abcd.pig"},
Object { mappers=15, jobname="abcd.pig"},
Object { mappers=12, jobname="abcd.pig"}]
I think the issue is the "=" sign after mappers and jobname. In the data property, it accepts colons = ":" and thats why the graph is not picking up values?
How do i fix this to get the graph working? and get the tooltip to show the jobname?

If I understand correctly, your problem is not only with the tooltip, the chart could not even render with your data. You set mappers and reducers as the property names of Y value, but how can highcharts know those properties are where it should pick Y values?
Changing properties mappers and reducers to y should make it work:
jobSummaryMappersPT.push({y: obj[i].maphours, jobname: obj[i].jobname}); // Filling of Array after Ajax Call
jobSummaryReducersPT.push({y: obj[i].reducehours, jobname: obj[i].jobname}); //Filling of Array
The code for tooltip looks fine to me.

Charts using Highcharts with multiple series from JSON

I have a JSON file of the following format :
[
{ name: 'Pay Off',
data: [ [2850,0],
[3135,0],
[3420,0],
[3705,0],
[3990,0],
[4275,0],
[4560,0],
[4845,0],
[5130,0],
[5415,0],
[5700,0],
[5985,285],
[6270,570],
[6555,855],
[6840,1140],
[7125,1425],
[7410,1710],
[7695,1995],
[7980,2280],
[8265,2565],
[8550,2850]
]
},
{
name: 'Profit',
data: [ [2850,-250],
[3135,-250],
[3420,-250],
[3705,-250],
[3990,-250],
[4275,-250],
[4560,-250],
[4845,-250],
[5130,-250],
[5415,-250],
[5700,-250],
[5985,35],
[6270,320],
[6555,605],
[6840,890],
[7125,1175],
[7410,1460],
[7695,1745],
[7980,2030],
[8265,2315],
[8550,2600]
]
}
]
I have to plot graph for 'Pay Off' and 'Profit' together. Even more plots maybe added to the list as per requirement. The data array has x-axis as 0th element and y-axis as 1st element.
What I am currently doing is the following -
$(document).ready(function() {
var options = {
chart: {
renderTo: 'container',
type: 'line'
},
title: {
text: 'PayOff Curve'
},
legend: {
layout: 'vertical',
align: 'right',
verticalAlign: 'middle',
borderWidth: 0
},
series: []
};
$.getJSON('data.json', function(list) {
var newseries = {
name: '',
data: []
};
$.each(list, function(i,item){
newseries.name = item.name;
newseries.data = item.data;
options.series.push(newseries);
});
// Create the chart
var chart = new Highcharts.Chart(options);
});
But I don't any graph at all. I can't figure out the issue with it as I am new to both JavaScript and Python. Please suggest an efficient method to do this.
Thanks for your help..

Your JSON isn't proper one, try to validate it. Properties names shold have double quotes, change from: name: 'Pay Off' to: "name": "Pay Off"

Your JSON is valid for a highcharts series - you don't need to try to transform it at all:
$(document).ready(function() {
var options = {
chart: {
renderTo: 'container',
type: 'line'
},
title: {
text: 'PayOff Curve'
},
legend: {
layout: 'vertical',
align: 'right',
verticalAlign: 'middle',
borderWidth: 0
},
series: []
};
$.getJSON('data.json', function(list) {
options.series = list; // <- just assign the data to the series property.
var chart = new Highcharts.Chart(options);
});
});
If that still doesn't work, open the console to see whether there's a JavaScript error.
Here's a fiddle.
