I need to show tooltips for only the last two series when hovering the mouse over the graph. In this example the idea will be to show only the tool tips for the values 1699 and 1750. The rest of the values can't show any tooltips when hovering the mouse. How can I achive that? I haven't found any way to do so. Is it possible? Thanks in advance.
(function () {
var categories= ['1350', '1400', '1450', '1500', '1550', '1699', '1750'];

You can use the formatter like this :
tooltip: {
formatter: function() {
if(this.points[0].key < (this.points[0].series.xData.length -2)){
return false;
}
var s = [];
s.push(this.x);
this.points.forEach(function(point) {
s.push('<b>' + point.series.name + '</b>: ' + point.y);
});
return s;
},
split: true
},
Fiddle
Not the cleanest code (there still an error in the console) but it's work.
Edit
Following Deep 3015 comment, code and fiddle updated
You can wrap tooltip.prototype.renderSplit method to show the tooltip only if the points have certain x values.
Highcharts.wrap(Highcharts.Tooltip.prototype, 'renderSplit', function (p, labels, points) {
if (!this.options.showOnLastTwo) {
return p.call(this, labels, points)
}
const point = points[0]
if (point) {
const allowedXs = point.series.xData.slice(-2)
if (allowedXs.includes(point.x)) {
return p.call(this, labels, points)
}
}
this.destroy()
})
And set in tooltip options showOnLastTwo flag to true:
tooltip: {
split: true,
showOnLastTwo: true
},
The flag is not necessary but the wrap changes Highcharts globally so it will affect every chart - the flag will prevent this.

I need the graph to display the values without rounding, the same as shown in the tooltip
In your chart options dataLabels use the formatter to define the display value, e.g.
dataLabels: {
formatter: function(val) {
return val.toFixed(2);
}
}
Full example with demo chart taken from official docs and added custom label:

For a Highcharts spline type chart, I want to completely remove the left and right spaces.
I tried to change some options but there is no success.
Spacing and margin keys did not make any appearance changes.
Does anyone have any info on how to remove the spaces, all help is welcome.
Example chart
Highcharts.chart('container', {
title: {
text: ''
},
chart: {
type: 'spline',
},
legend: {
display: false
},
xAxis: {
categories: [7, 13, 16, 18, 19, 20, 29, 22, 25, 38, 23, 26, 28, 29, 33],
},
yAxis: {
tickPosition: 'inside',
min: 0,
title: {
text: null
},
floor: 0,
tickWidth: 1
},
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]
}]
});
<script src="https://code.highcharts.com/highcharts.js"></script>
<div id="container" style="height: 400px; width: 500px"></div>
These gaps are added when using the xAxis.categories option. If you remove these options then it works the way you want. For tick positioning in this case it is better to set other available API options. Find out more about it here: https://api.highcharts.com/highcharts/xAxis.tickPositions
I take one of the examples posted and slightly modify it by removing some data. When the sets don't have the same number of data points, the tooltips stop displaying.
Please see the following two examples. The first one being the one posted in the docs. The second, the modified version. When hovering starting from the end data points, the tooltip doesn't display anything for the last columns.

Your codepen example uses an older version of ApexCharts.
Please update by pulling the latest version here
https://cdn.jsdelivr.net/npm/apexcharts#latest
Also, if you have a different number of data-points in each series, you can turn off shared tooltip and only show the tooltip when the user hovers over bars/markers directly.
tooltip: {
shared: false,
intersect: true
}
I'm using Highcharts to create a grouped bar chart and looking to add markers for each bar.
I've created a multi-series (bar + scatter) plot that is similar to what I want, but since there is no "grouped scatter" plot, the circle marks are centered (Screenshot attached below).
Is there a way to change it so the marks appear on the same row as the bar?
JSFiddle
Highcharts Config
{
chart: {
type: 'bar'
},
title: {
text: ''
},
xAxis: {
categories: ['One', 'Two', 'Three']
},
tooltip: {
enabled: true
},
series: [
{
name: '2015',
data: [7, 8, 9]
},
{
name: '2015 Goal',
marker: {
symbol: 'circle'
},
data: [5, 6, 6],
type:'scatter'
},
{
name: '2016',
data: [9, 9, 10]
},
{
name: '2016 Goal',
marker: {
symbol: 'circle'
},
data: [10,12,13],
type:'scatter'
}
]
}
Set x value for the point. By default x values for the scatter are integers - 0, 1, 2 so they are centered according to the category. You can move them a little by 0.15 and then in the pointFormatter round those values.
series: [{
name: '2015',
data: [7, 8, 9]
}, {
name: '2015 Goal',
marker: {
symbol: 'circle'
},
data: [
[-0.15, 5],
[1 - 0.15, 6],
[2 - 0.15, 6]
],
type: 'scatter'
}, {
name: '2016',
data: [9, 9, 10]
}, {
name: '2016 Goal',
marker: {
symbol: 'circle'
},
data: [
[0.15, 10],
[1 + 0.15, 12],
[2 + 0.15, 13]
],
type: 'scatter'
}]
In pointFormatter:
plotOptions: {
scatter: {
tooltip: {
pointFormatter: function() {
return `x: <b>${Math.round(this.x)}</b><br/>y: <b>${this.y}</b><br/>`
}
}
}
},

I am trying to customize the tooltip of area chart. I am using Highchart for this.
I am plotting 3 series in area chart. My requirement is to show tooltip at fixed location in chart which is top center. Now, when i put cursor at any point then tooltip should show all series name and their current value where the cursor is. Refer below image:
Currently i am able to show tooltip on top - center and putting mouse at any point is showing current series name and data but it is showing current series name in all 3 places.
Highchart option:
Highcharts.chart('container', {

Please help. Thanks in advance!
It might be difficult to achieve the desired result without tooltip.formatter.
This is how you can build tooltip text in a formatter:
formatter: function(tooltip) {
const points = this.points;
let str = '<table><tr>';
points.forEach(point => {
str += '<td style="text-align:center">' + point.y + '</td>';
});
str += '</tr><tr>';
points.forEach(point => {
str += '<td><span style="font-size:20px;color:' + point.color + '">●</span> ' + point.series.name + '</td>';
});
str += '</tr></table>';
return str;
},
And position it in the center of the chart:
positioner: function () {
const chart = this.chart;
return { x: (chart.plotWidth + chart.marginRight - this.label.getBBox().width) / 2, y: chart.plotTop + 10 };
}
Example and output
https://jsfiddle.net/eb3ou25v/
You can achieve desired result using pointFormat method
This is how you can use this
pointFormat: '<table style="text-align:center; display: inline-block; background: white;"><tr><td>{point.y}</td></tr>' +
'<tr><td><span style="font-size:20px;color:{series.color}">●</span> {series.name}</td></tr></table>',
positioner: function () {
const chart = this.chart;
return { x: (chart.plotWidth + chart.marginRight - this.label.getBBox().width) / 2, y: chart.plotTop - 20 };
}
