how to set negative axes intervals in highcharts

I want to set intervals of negative and positive axes differently like my data in positive have values around 4000000 and in negative I have -2, -5 , -10 ..etc such values and they all are dynamic .
What's the best way to do that except Tick positioner? or with tick positioner?
Using Highcharts in Angular

You can use two y-axes and assign series to the appropriate one based on values.
yAxis: [{
height: '50%',
min: 0
}, {
top: '50%',
height: '50%',
offset: 0,
max: 0
}],
series: [{
data: [10, 20, 30, 40, 50, 60, 70, 80, 90, 100],
}, {
data: [0, -1, 0, -2, -2, -3, -2, -5, 0, -2],
yAxis: 1,
}]

I'm using combination chart with four different data arrays in series and each one them is expected to have negative values
this is my chart
the code here
export const getAirlinesChartOption = (data) => {
let val;

allValues.push(tpSegments[index])
allValues.push(amadeusSegments[index])
allValues.push(sabreSegments[index])
allValues.push(lytpSegments[index])
})
console.log('allValues',allValues)
const neg = allValues.filter(function (v) {
return v < 0;
}),
pos = allValues.filter(function (v) {
return v > 0;
});
let positiveCount = pos.length;
let negativeCount = neg.length;
let posMax = Math.max(...pos)
let negMax = Math.max(...neg)
console.log('pos',pos)
console.log('neg',neg)
console.log('posMax',posMax)
console.log('negMax',negMax)
let sortedPosArray = pos.sort(function(a, b) {
return a - b;
});
let sortedNegArray = neg.sort(function(a, b) {
return a - b;

As you can see for R P 0.00000024 is getting converted into 2.4e-7. But I want it show as is i.e. 0.00000024.
For other decimals numbers, it's perfectly fine, but for the above-mentioned decimal, it's converting into exponential. Is there any option to set? Is this possible?

With the help of this solution, I patched my problem. If anyone got better solution let me know.
Number.prototype.noExponents = function() {
var data = String(this).split(/[eE]/);
if (data.length == 1) return data[0];
var z = '',
sign = this < 0 ? '-' : '',
str = data[0].replace('.', ''),
mag = Number(data[1]) + 1;
if (mag < 0) {
z = sign + '0.';
while (mag++) z += '0';
return z + str.replace(/^\-/, '');
}
mag -= str.length;
while (mag--) z += '0';
return str + z;

Generate Chart With 2 Datasets Charts.js

I can get my chart to display with 1 dataset no problem, but adding in the second one to the syntax below gives me an error of
Uncaught Syntax Error: Unexpected Token }
This is my syntax - what is causing the issue?
var ctx = document.getElementById('canvas').getContext('2d');
var chart = new Chart(ctx, {
datasets: [{
type: 'bar',
labels: labelsarr,
label: 'Red Team',
backgroundColor: 'rgba(0, 129, 214, 0.8)',
data: [values]
}, {
type: 'line',
label: 'Green Team',
backgroundColor: 'rgba(0,129, 218, 0.8)',
data: [values1]
}, {
options: {
tooltips: {
callbacks: {
label: function (t, d) {
var xLabel = d.datasets[t.datasetIndex].label;
var yLabel = t.yLabel >= 1000 ? '$' + t.yLabel.toString().replace(/\B(?=(\d{3})+(?!\d))/g, ",") : '$' + t.yLabel;
return xLabel + ': ' + yLabel;
}
}
},
legend: {
display: false,
position: 'top',
},
scales: {
yAxes: [{
ticks: {
beginAtZero: true,
callback: function (value, index, values) {
if (parseInt(value) >= 1000) {
return '$' + value.toString().replace(/\B(?=(\d{3})+(?!\d))/g, ",");
} else { return '$' + value; }
}
}
}]
}
},
plugins: [{
beforeDraw: function (chart) {
var labels = chart.data.labels;
}
}]
}
}]
);

The second last line of your code }] is backwards. It should be ]}
reconfigured structure:
var ctx = document.getElementById('canvas').getContext('2d');
var chart = new Chart(ctx, {
type: 'bar',
data: {
datasets: [
{
label: 'Red Team',
data: values,
backgroundColor: 'rgba(0, 129, 214, 0.8)',
},
{
label: 'Green Team',
data: values1,
type: 'line',
backgroundColor: 'rgba(0,129, 218, 0.8)',
}
],
labels: labelsarr
},
options: {
callbacks: {
label: function (t, d) {
var xLabel = d.datasets[t.datasetIndex].label;
var yLabel = t.yLabel >= 1000 ? '$' + t.yLabel.toString().replace(/\B(?=(\d{3})+(?!\d))/g, ",") : '$' + t.yLabel;
return xLabel + ': ' + yLabel;
}
},

ticks: {
beginAtZero: true,
callback: function (value, index, values) {
if (parseInt(value) >= 1000) {
return '$' + value.toString().replace(/\B(?=(\d{3})+(?!\d))/g, ",");

Can not read property 'Concat' of Undefined

I am attempting to use the charts.js plug-in and do a combo chart, but I want the line to be on top of the bar. This is the syntax that I am using, and both my arrays linedata & bardata are populated but whenever I run this syntax I get an error of
Uncaught TypeError: Cannot read property 'concat' of undefined
at n (Chart.min.js:11)
at t.update (Chart.min.js:11)
at t.construct (Chart.min.js:11)
at new t (Chart.min.js:12)
at trends:507
This is the syntax I utulize - where is the error?
var ctx = document.getElementById('canvas').getContext('2d');
var chart = new Chart(ctx, {
data: {
labels: labelsarr,
datasets: [{
type: 'line',
fill: false,
label: 'Line Example',
backgroundColor: 'rgba(255,0,0,1)',
borderColor: 'rgba(255,0,0,1)',
data: linedata
}, {
type: 'bar',
label: 'Bar Example',
backgroundColor: 'rgba(0, 129, 214, 0.8)',
data: bardata
}]
},
options: {

var xLabel = d.datasets[t.datasetIndex].label;
var yLabel = t.yLabel >= 1000 ? '$' + t.yLabel.toString().replace(/\B(?=(\d{3})+(?!\d))/g, ",") : '$' + t.yLabel;
return xLabel + ': ' + yLabel;
}
}
},
legend: {
display: false,

},
scales: {
yAxes: [{

return '$' + value;
}
}
}
}]
}
},
plugins: [{
beforeDraw: function(chart) {
var labels = chart.data.labels;
}
}]
});
Edit
This is how the arrays are being populated - values passed from php
var ldata = <?php echo $ldata; ?>;
var values = [];
for (var i = 0; i < ldata.length; i++) {
values.push(ldata[i]);
}
var bdata = <?php echo $bdata; ?>;
var values1 = [];
for (var i = 0; i < bdata.length; i++) {
values1.push(bdata[i]);
}

You would have to set the chart type in the main chart option, not inside the dataset (the second one) :
var chart = new Chart(ctx, {
type: 'bar',
data: {
...
Here is the working version of your code :
var labelsarr = ['A', 'B', 'C'];
var linedata = [2, 5, 3];
var bardata = [4, 2, 6];
var ctx = document.getElementById('canvas').getContext('2d');
var chart = new Chart(ctx, {
type: 'bar', //<-- set here
data: {
labels: labelsarr,
datasets: [{
type: 'line',
fill: false,
label: 'Line Example',
backgroundColor: 'rgba(255,0,0,1)',
borderColor: 'rgba(255,0,0,1)',
data: linedata
}, {
label: 'Bar Example',
backgroundColor: 'rgba(0, 129, 214, 0.8)',
data: bardata
}]
},
options: {
tooltips: {
callbacks: {
label: function(t, d) {
var xLabel = d.datasets[t.datasetIndex].label;
var yLabel = t.yLabel >= 1000 ? '$' + t.yLabel.toString().replace(/\B(?=(\d{3})+(?!\d))/g, ",") : '$' + t.yLabel;
return xLabel + ': ' + yLabel;
}
}
},
legend: {
display: false,
position: 'top',
},
scales: {
yAxes: [{
ticks: {
beginAtZero: true,
callback: function(value, index, values) {
if (parseInt(value) >= 1000) {
return '$' + value.toString().replace(/\B(?=(\d{3})+(?!\d))/g, ",");
} else {

HighCharts Stacked Column Adding Onclick Event to the chart

I am working on a Highchart column chart.
I need to add an onclick event to it so I can get data back when I click on the different columns.
Here is my current full code.
var chart;
$(function () {
$.ajax({
url: 'url here',
method: 'GET',
async: false,
success: function(result) {
themainData = result;
}
});
var mainData = [themainData];
var chList=[];
var voList=[];
var coList=[];
for (var i = 0; i < mainData[0].ch.length; i++) {
var obj = mainData[0].ch[i];
var chlst = obj.name;
var vl = obj.st.vo;
var cl = obj.st.co;
chList.push(chlst);
voList.push(vl);
coList.push(cl);
}
var chart = {
type: 'column',
};
var title = {
text: 'Vo and Co'
};
var xAxis = {
categories: chList
};
var yAxis ={
min: 0,
title: {
text: 'Ch'
},
stackLabels: {
enabled: true,
style: {
fontWeight: 'bold',
color: (Highcharts.theme && Highcharts.theme.textColor) || 'gray'
}
}
};
var legend = {
align: 'right',
x: -30,
verticalAlign: 'top',
y: 25,
floating: true,
backgroundColor: (Highcharts.theme && Highcharts.theme.background2) || 'white',
borderColor: '#CCC',
borderWidth: 1,
shadow: false
};
var tooltip = {
formatter: function () {
return '<b>' + this.x + '</b><br/>' +
this.series.name + ': ' + this.y + '<br/>' +
'Total: ' + this.point.stackTotal;
}
};
var plotOptions = {
column: {
stacking: 'normal',
dataLabels: {
enabled: true,
color: (Highcharts.theme && Highcharts.theme.dataLabelsColor) || 'white',
style: {
textShadow: '0 0 3px black'
}
}
}
};
var credits = {
enabled: false
};
var series= [{
name: 'Vo',
data: voList
}, {
name: 'Co',
data: coList
}];
var json = {};
json.chart = chart;
json.title = title;
json.xAxis = xAxis;
json.yAxis = yAxis;
json.legend = legend;
json.tooltip = tooltip;
json.plotOptions = plotOptions;
json.credits = credits;
json.series = series;
$('#container').highcharts(json);
});
Where do I add the onclick event here?

You can add the click event on the chart, series, or point. I think it makes sense in your case to add the click event to the series.
var series= [{
name: 'Vo',
data: voList
events: {
click: function (event) {}
}
}, {
name: 'Co',
data: coList
}];
event.point is the point that is clicked on. See http://api.highcharts.com/highcharts/series%3Cbar%3E.events.click

This works for me,
chart: {
type: "bar",
},
title: {
text: "Stacked bar chart",
},
xAxis: {
categories: ["Apples", "Oranges", "Pears", "Grapes", "Bananas"],
},
yAxis: {
min: 0,
title: {
text: "Total fruit consumption",
},
},
legend: {
reversed: true,
},
plotOptions: {
series: {
cursor: 'pointer',
stacking: "normal",
events: {
click: function(event) {
alert(
this.name + ' clicked\n' +
'Alt: ' + event.altKey + '\n' +
'Control: ' + event.ctrlKey + '\n' +
'Meta: ' + event.metaKey + '\n' +
'Shift: ' + event.shiftKey
);
}
}
},
},
series: [{
name: "John",
data: [5, 3, 4, 7, 2],
},
{
name: "Jane",
data: [2, 2, 3, 2, 1],
},
{
name: "Joe",
data: [3, 4, 4, 2, 5],
},
],
});```
