HighChart is not working with multiple axis - highcharts

I want to construct multiple y-axis spline Highchart, but I am getting Null in series.
When I use data manually so it works fine, but When I fetch data from URL it does not work. Also, I am going to prepare a function for creating multiple y-axes.
Can anyone please help me where I am wrong?
Here is my code
<script type="text/javascript">
var axisdata = [{url:"",text:"", yAxis: 1, scrollbar: true,type: "spline"},
{url:"", text:"", yAxix: 2, scrollbar:true, type: "spline"}];
var HighChartObj = {
title: {
text: 'Exchange Rates'
},
scrollbar: {
enabled: true,
showFull: false
},
yAxis: [],
series: [],
rangeSelector: {
selected: 1,
buttonTheme: {
visibility: 'hidden'
},
labelStyle: {
visibility: 'hidden'
},
inputDateFormat: '%H:%M:%S.%L'
},
};
function a(){
var defer = $.Deferred();
z = -1;
var axisLength = axisdata.length - 1;
jQuery.each(axisdata, function(key, value){
$.getJSON( value.url, function (data) {
var dataLength = data.length,
i = 0;
minValue = data[0].open;
maxValue = data[0].open;
var finalData = [];
var new_from_date = 0;
var new_to_date = 0;
var minValue;
var maxValue;
for (i; i < dataLength; i += 1) {
if(i == (dataLength + 99 - dataLength)){
new_to_date = (data[i].start*1000);
}
finalData.push([
(data[i].start*1000),
data[i].open,
]);
if (data[i].open < minValue) {
minValue = data[i].open;
}
else{
if(data[i].open > maxValue){
maxValue = data[i].open;
}
}
}
HighChartObj.xAxis = {
type: 'datetime',
min: new_from_date,
max: new_to_date,
range: new_to_date - new_from_date,
ordinal: false,
endOnTick: false,
startOnTick: false
};
z++;
HighChartObj.yAxis[z] = {
title: {
text: value.text
},
opposite: true,
min: minValue,
max: maxValue,
height: "100%",
scrollbar: {
enabled: value.scrollbar
}
};
var series = {
"type": value.type,
"name": value.text,
"yAxis": value.yAxis,
"id": value.text.toLowerCase().replace(' ', ''),
"zIndex": 1,
"data": finalData
};
if(HighChartObj.series == null){
HighChartObj.series = new Array();
}
HighChartObj.series[z] = series;
if(key == axisLength){
defer.resolve();
}
});
});
return defer.promise();
}
function b(){
// console.log(HighChartObj.series = HighChartObj.test);
console.log(HighChartObj);
Highcharts.stockChart('container', HighChartObj);
}
$.when(a()).then(b());
</script>

Try fetching data like this. Please data in different variables and then pass it to HighChart Object.
function a(){
z = -1;
var axisLength = axisdata.length - 1;
var dataSeries = new Array()
var dataYaxis = new Array();
jQuery.each(axisdata, function(key, value){
var axisValue = value;
$.ajax({
dataType: "json",
url: axisValue.url,
success: function (data) {
var dataLength = data.length,
i = 0;
minValue = data[0].open;
maxValue = data[0].open;
var finalData = [];
var new_from_date = 0;
var new_to_date = 0;
var minValue;
var maxValue;
for (i; i < dataLength; i += 1) {
if(i == (dataLength + 99 - dataLength)){
new_to_date = (data[i].start*1000);
}
var date = (data[i].start*1000);
finalData.push([
date,
data[i].open,
]);
if (data[i].open < minValue) {
minValue = data[i].open;
}
else{
if(data[i].open > maxValue){
maxValue = data[i].open;
}
}
}
z++;
HighChartObj.xAxis = {
type: 'datetime',
min: new_from_date,
max: new_to_date,
range: new_to_date - new_from_date,
ordinal: false,
endOnTick: false,
startOnTick: false
};
var yAxis = {
title: {
text: axisValue.text
},
opposite: false,
min: minValue,
max: maxValue,
height: "100%",
scrollbar: {
enabled: axisValue.scrollbar
}
};
dataYaxis.push(yAxis);
var series = {
type: axisValue.type,
name: axisValue.text,
id: axisValue.text.toLowerCase().replace(' ', ''),
zIndex: 2,
data: finalData
};
dataSeries.push(series);
if(key == axisLength){
HighChartObj.yAxis = dataYaxis;
HighChartObj.series = dataSeries;
b();
}
}
});
});
}

How to make the regression line through the origin in highcharts

I am trying to make the regression to start from the origin , x=y=0. Is this possible to do. some say it is not good to do so but for some purposes I need to make the line through the origin. I am using highcharts.
How about adding a point to the regression series with x = y = 0 and setting the marker to disabled in order to hide it?

sx = jStat.stdev(arrHeight);
meanY = jStat(arrWeight).mean();
meanX = jStat(arrHeight).mean();
b = r * (sy / sx);
a = meanY - meanX * b;
//Set up a line
let y1, y2, x1, x2;
x1 = jStat.min(arrHeight);
x2 = jStat.max(arrHeight);
y1 = a + b * x1;
y2 = a + b * x2;

What is the highchart pie data structure

I have create a HighCharts Pie as follows :
This a parts of my source:
series: [{
name: 'Temps d\'arrêt',
type: 'pie',
data: getTempsDArretSeries(data2),
center: [35, 0],
size: 100,
showInLegend: false,
dataLabels: {
enabled: false
}
,tooltip: {
valueSuffix: ' min '+'<br><b>{point.percentage:.1f}%</b>',
}
,title: {
text: 'Temps d\'arrêt'
},
}]
My function getTempsDArretSeries(data2) is :
function getTempsDArretSeries(data){
var array = new Array();
var duree = 0;
var memProduit = 0;
$(data).each(function(){
if(memProduit!=0){
if(memProduit != parseInt(this.efcode)){
array.push(duree);
memProduit = parseInt(this.efcode);
duree = parseInt(this.efdur);
}else{
duree += parseInt(this.efdur);
}
}else{
duree += parseInt(this.efdur);
memProduit = parseInt(this.efcode);
}
})
array.push(duree);
return array;
}
I have the result as follows on my chart :
chart
It is possible to put something like :
name: memProduit,
y: duree,
sliced: true,
selected: true
for all lines.

Export Highcharts polar chart csv with categories in place of polar coordinates

I've implemented a polar chart in which each series has 4 values corresponding to 4 categories. When I export the chart csv, the category column contains polar coordinates. I would like to replace these with the corresponding category name. How do I do this?
Adding the categories to each series, had no effect. I also tried adding a categories property to the xAxis, but it had not effect. An xAxis.label formatter successfully returns the category name for each data polar coordinate.
const options = {
chart: {
polar: true,
},
title: {
text: '',
},
tooltip: {
valueDecimals: 2,
headerFormat: '<br/>',
},
legend: {},
pane: {
startAngle: 0,
endAngle: 360,
},
xAxis: {
tickInterval: 45,
min: 0,
max: 360,
labels: {
// eslint-disable-next-line
formatter: function() {
switch (this.value) {
case 45:
return '<b>Experience</b>'
case 135:
return '<b>Frictionless</b>'
case 225:
return '<b>Low Price</b>'
case 315:
return '<b>Brand</b>'
default:
return ''
}
},
},
},
yAxis: {
min: 0,
max: 10,
labels: {
format: '{}',
},
},
plotOptions: {
series: {
pointStart: 45,
pointInterval: 90,
},
column: {
pointPadding: 0,
groupPadding: 0,
},
},
series: kahnSeries,
}
You need to use categories property, but without options like: pointInterval, pointStart, min and max:
xAxis: {
categories: ['Experience', 'Frictionless', 'Low Price', 'Brand']
},
Live demo: http://jsfiddle.net/BlackLabel/z8cm1p39/
API Reference: https://api.highcharts.com/highcharts/xAxis.categories
To avoid changing the chart's current display, I wrapped the getCSV function and replaced the CSV category values. If there was a simpler way, please share it.
{
(function (H) {
H.wrap(H.Chart.prototype, 'getCSV', function (
proceed,
useLocalDecimalPoint
) {
// Run the original proceed method
const result = proceed.apply(
this,
Array.prototype.slice.call(arguments, 1)
)
const itemDelimiter = ','
const lineDelimiter = '\n'
const rows = result.split(lineDelimiter)
let newResult = ''
let rowCategories = false
rows.forEach((row, rowIndex) => {
const columns = row.split(itemDelimiter)
if (rowIndex === 0 && columns[0] === '"Category"') {
rowCategories = true
}
if (rowIndex > 0 && rowCategories) {
let newRow = formatter(columns[0])
columns.forEach((column, columnIndex) => {
if (columnIndex > 0) {
newRow += itemDelimiter
newRow += column
}
})
newResult += newRow
} else {
newResult += row
}
if (rowIndex < rows.length - 1) {
newResult += lineDelimiter
}
}
)
return newResult
})
}(Highcharts))

why x-axis showing alternate months rather every month?

Also, attaching the screenshot of the rendered highchart with drilldown.
,
Now drilldown graph(same sort a issue)
EDIT:
It turnsout to be a zoom issue, i.e if i zoomout enough, then it shows all points. So, how to show every point without zooimg out .
Working fiddle:

Use tickInterval property and set it to one month:
xAxis: {

tickInterval: 30 * 24 * 3600 * 1000,
labels: {
step: 1

Memory leak problems for column chart

I am not good at speaking English. Please understand.
I'm having a memory leak problem when using the stack column chart.
We update the data using setCategories, setData on a stack column chart every 2 seconds.
But, the memory usage continues to increase and the browser will be forcibly terminated.
The only thing that program does is call setCategories, setData. Is there anything I need to do to clean up the memory?
The test environment is os: windows7, windows10, browser: lastest version chrome 57.0.2987.133
you can see that you keep increasing after 1, 3, 5, 7, 10, 15, and 20 minutes.
Memory usage increases with time, so you can check it immediately.
You can check memory usage in the task window by running [shift + esc] shortcut in Chrome.
Send the sample code as an attachment. Thank you.
JQuery and Highcharts(5.0.10) use the latest version.
