using custom formatter for highstock's yaxis labels formatter - javascript

I'm using custom formatter for yaxis labels of Highstock.
it works except as it should.
I want to it returns for example "15 bar" instead of "15000 bar" as when default formatter does.
Here is my snippet code:
yAxis.labels.formatter = "function(){return Highcharts.numberFormat(this.value, 0, ',') +' " + portSetting.QuantityUnit + "'}";
tanks.

The formatter should be a function and it looks like you are assigning a string.
So instead of:
yAxis.labels.formatter = "function(){return Highcharts.numberFormat(this.value, 0, ',') +' " + portSetting.QuantityUnit + "'}";
you should write a function like:
yAxis.labels.formatter = function () {
return
Highcharts.numberFormat(this.value, 0, ',') +
' "' + portSetting.QuantityUnit + '"';
};

Highcharts complex tooltip formatting issue with embedded html link

I am trying to format the tooltip in a highcharts bubble chart
There is a lot of information I'd like to display with custom formats etc so I'm using the formatter function. It is all working fine except for the last line which is a html link (href tag). I want to be able to click on this link in the tooltip and be redirected to the new page however, currently, even though I can see the row highlighted with a link, I'm not being able to click on the link when it renders in the tooltip
Here's the code
const chartOptions = {
chart: {
type: 'bubble',
plotBorderWidth: 1,
zoomType: 'xy',
height: 600,
},
title: {text: null},
legend: {
enabled: true
},
tooltip: {
useHTML: true,
formatter: function () {
return '<b>' + Highcharts.dateFormat('%e-%b', new Date(this.x)) + ' ' + this.y + '</b><br/>' +
'<b>' + 'ACV: ' + '</b>'+ '$' + Math.round(this.point.ACV / 1000).toFixed(1) + 'K' + '<br/>' +
'Type: ' + this.point.OPP_COB + '<br/>' + 'Name: ' + this.point.REP_NAME + '<br/>' +
'Link: ' + ' Click here '
}
},
}
I've tried lots of options for a while but haven't had any luck. Any help would be much appreciated. Thanks
You need to set pointerEvents property to 'auto':
tooltip: {
style: {
pointerEvents: 'auto'
}
}

Highcharts passing variable to tooltip

Hi I am trying to pass a variable to my tooltip using setData.
Here is a piece of my code explaining how I am setting the chart data, this code doesn't pass the sensorValue to my tooltip yet:
nitrogenDioxide = [];
$.each(data['NO2'], function(key, value) {
nitrogenDioxide.push([value.ts * 1000, value.rating]);
});
chart_2_1.series[0].setData(nitrogenDioxide);
chart_2_1.series[0].update({name:'Nitrogen Dioxide'}, true);
Here is the code I used to create my tooltip:
tooltip: {
shared: true,
useHTML: true,
formatter: function () {
var tooltipcontent = '<b>' + moment.unix((this.points[0].key / 1000)).format("DD/MM/YYYY HH:mm"); + '</b>';
tooltipcontent += '<table style="width:100%">';
$.each(this.points, function () {
console.log(this);
tooltipcontent += '<tr><td>' + this.y.toLocaleString() + '</td></tr>';
tooltipcontent += '<tr><td>' + sensorValue + '</td></tr>';
});
tooltipcontent += '</table>';
return tooltipcontent;
}
}
As you can see I have a variable called sensorValue in my tooltip. In the foreach loop I have a rating value (y-axis) and a sensor value. I want to pass that sensor value to me tooltip.
I have seen multiple ways of doing this online but none of them set the data the way I do, they do it like so:
new Highcharts.Chart( {
...,
series: [ {
name: 'Foo',
data: [
{
y : 3,
myData : 'firstPoint'
},
{
y : 7,
myData : 'secondPoint'
},
{
y : 1,
myData : 'thirdPoint'
}
]
} ]
} );
I have tried something like this but didn't know how to call this extra value in the tooltip:
nitrogenDioxide = [];
$.each(data['NO2'], function(key, value) {
nitrogenDioxide.push([value.ts * 1000, value.rating, value.value]);
});
In the above code I have pushed the sensor value into the nitrogenDioxide[] array.
I have tried my best to explain what I am trying to do, in my head the explanation makes sense but if it doesnt to you please let me know. Thank you in advance for any help.
I hope I understood correctly what is your issue and the demo posted below will be helpful for you.
When an array with an additional value is passed (sensorValue in your case) it can be retrieved inside formatter using this approach:
get hovered point index: this.point.index
use the point index to get additional value from this.series.userOptions.data array
Code:
Highcharts.chart('container', {
tooltip: {
formatter: function() {
var point = this.point,
series = this.series,
pointIndex = point.index,
text,
additionalValue;
text = '<span style="color:' +
this.color + '">\u25CF</span> ' +
series.name +
': <b>' +
this.y +
'</b><br/>';
additionalValue =
series.userOptions.data[pointIndex][2];
text += '<br> Additional value: ' +
additionalValue;
return text;
}
},
series: [{
data: [
[1, 2, 'aaa'], // 'aaa' is an additional value
[2, 5, 'bbb'],
[3, 9, 'ccc']
]
}],
});

Highcharts add symbol on tooltip when over 100 or 1000

I am trying to make the tooltip when it is 100 + and 1000 + Have a symbol after it on the toolbar but also have it so that shared: true. Also on the graph when it is say 2394 I am after it to round it down to 2.39 so the graph is not so large and then on the tool bar it would show 2.39K.
I have tried quite a bit and I am not able to figure this out look all over stack overflow and not found anything.
http://jsfiddle.net/sb7n32zn/22/
This is what i currently have:
tooltip: {
shared: true,
pointFormat: '<span style="color:{series.color}">{series.name}: <b>{point.y:,.2f}</b><br/>',
}
You need to use a tooltip.formatter which and detect values > 1000. Then use Highcharts.numberFormat and convert number.
formatter: function() {
var points = this.points,
each = Highcharts.each,
txt = '<span style="font-size: 10px">' + points[0].key + '</span><br/>',
H = Highcharts,
value,
numericSymbolDetector;
each(points, function(point, i) {
value = point.y;
numericSymbolDetector = Math.abs(point.y);
if (numericSymbolDetector > 1000) {
value = H.numberFormat(value / 1000, 2, '.','' ) + 'k';
}
txt += '<span style="color:' + point.series.color + '">' + point.series.name + ': <b>' + value + '</b><br/>';
});
return txt;
}

dataClasses name in tooltip through formatter function [Highcharts]

I did a pollution table based on a heat map chart, the tooltip use formatter function. I would like to know how can I make the tooltip to show the different categories of data (dataClasses name in colorAxis) when hover the mouse (ex: Norma, Regular, etc..) instead of showing the values, like it does now ( 90 µg/m³, 220 µg/m³, etc...)
Here's the table: https://jsfiddle.net/Ruloco/58q60968/
Here's the tooltip code:
tooltip: {
formatter: function () {
return '<b>' + this.series.xAxis.categories[this.point.x] + '</b><br><b>' + this.point.value + '</b> µg/m³ <br><b>' + this.series.yAxis.categories[this.point.y] + '</b>';
}
},
Thanks in advance!
You can access a point's data class name via this.series.colorAxis.dataClasses[this.point.dataClass].name.
tooltip: {
formatter: function () {
return '<b>' + this.series.xAxis.categories[this.point.x] + '</b><br><b>' +
this.series.colorAxis.dataClasses[this.point.dataClass].name + '</b><br><b>' + this.series.yAxis.categories[this.point.y] + '</b>';
}
},

Customize tooltip in Highcharts.js?

I have the following question:
How can I customize the chart tooltip using Highcharts.js
library?
any help is appreciated.
If you want to customize the tooltip of your highcharts.js chart, you can do it defining a formatter
for the tooltip property of your chart_object, like this:
var chart_object = {
(...)
tooltip: {
formatter: function() {
return '<span>' + 'My HTML ' + this.x + '</span> : <b>' + this.y + '</b>';
}
},
(...)
}
You will use the chart_object later to initialize your Highcharts chart:
var chart = new Highcharts.Chart(chart_object );
I hope it helps.
