Can someone post an example of a custom aggregate method in highchart?I want to create a custom aggregate method that groups the following points into a single point with the tool tip ?
I have an array that has the following data
array1 :['apple',2,4,10,12.5]
I want the above array to be represented in a single grouped point with a tool tip
that shows as follows
apple
no of apples : 2
min:4
max:10
mean:12.5
I would process the data to get it into a format highcharts recognizes and then add the extra data to the point object. You can reference that extra data in the tooltips formatter function:
$(function () {
var input = [['apple',2,4,10,12.5],
['pear',1,5,10,12],
['orange',3,4,10,13.5],
['grape',4,4,10,11.5]],
data = [],
categories = [];
for (i=0;i<input.length;i++) {
categories.push(input[i][0]);
data.push({x: i,
y: input[i][1],
myMin: input[i][2],
myMax: input[i][3],
myMean: input[i][4]});
}
$('#container').highcharts({
tooltip: {
formatter: function() {
return '<b>'+ this.x +'</b><br/>' +
'No. of ' + this.x + ': ' + this.y + '<br/>' +
'min : ' + this.point.myMin + '<br/>' +
'max : ' + this.point.myMax + '<br/>' +
'mean : ' + this.point.myMean;
}
},
xAxis: {
categories: categories
},
chart: {
marginRight: 50
},
series: [{
data: data
}]
});
});

Highcharts: I have a shared tooltip with 3 default bullets. I need to add custom information to the 3rd bullet (or series).
I need Bullet C to show its default value, but also show what percentage it is of Bullet B. In the screenshot below, Bullet C would say: "Good Condition: 3,448 (32% of Assessed).
My question is 2 parts:
How do I customize only the third bullet tooltip?
How do I find out what percentage of Bullet B is represented by Bullet C? (in my example, 3,448 is 32% of 10,697, but how do i find that using highcharts?)
Update: This code formats the bullet and partially answers my first question (except it's missing the comma for thousands format):
return '<span style="color:' + this.series.color + '">● </span>' + this.series.name + ':<b>' + this.y + '</b><br/>';
You can define individual tooltip options for a series, in your case you need to use pointFormatter function, for example:
series: [..., {
...,
tooltip: {
pointFormatter: function() {
var series = this.series.chart.series,
percentage = Highcharts.numberFormat(
this.y / series[1].points[this.index].y * 100,
2
);
return '<span style="color:' +
this.color + '">●</span> ' +
this.series.name + ': <b>' +
Highcharts.numberFormat(this.y, 0) +
'</b> Percentage: ' + percentage + '%<br/>'
}
}
}]

I have created a column chart using Highchart, and would like to add additional text and value to the tooltip, without using the point.y or point.x and i am not trying to work out the sum/avg, its a self-generated value and text.
Any suggestion please.Please see highlighted example
Declare tooltip options with formatter function:
options: {
...,
tooltip: {
formatter: function () {
return 'The value for <b>' + this.x +
'</b> is <b>' + this.y + '</b>'
+ '<br/>' + 'Extra data: <b>' + this.point.extra + '</b>';
},
}
}
And define series data like below:
data:[
{
y: 49.9,
extra: 49.9
},
{
y: 71.5,
extra: 71.5
},
...
],
See jsfiddle code here
I have the following highcharts graph
https://jsfiddle.net/deemgfay/
and I am trying to display the "Consum Test" values in the tooltip but without adding them to the series. I just want to add Consum (l/100km)
Total Consum (l) to the series. Is that possible with hightcharts? Please see the screenshot below.
You can set the extra series to be hidden and ignored in legend:
visible: false,
showInLegend: false
Then use tooltip formatter function (useHTML must be enabled) to display points from all series in the shared tooltip regardless of their visibility:
formatter: function() {
var html,
originalPoint = this.points[0];
// header
html = "<span style='font-size: 10px'>" + originalPoint.x + "</span><br/>";
// points
originalPoint.series.chart.series.forEach(function(series) {
var point = series.points.find((p) => p.x === originalPoint.point.x);
html += "<span style='color: " + series.color + "'>\u25CF</span> " + series.name + ": <b>" + point.y + "</b><br/>"
});
return html;
}

API references:
http://api.highcharts.com/highcharts/tooltip.formatter
http://api.highcharts.com/highcharts/tooltip.useHTML
This can be done by using tooltip.formatter. Here I append to tooltip info based on index of current series from index of required extra array.
formatter: function() {
var s = '<b>' + this.x + '</b>';
var reqpoint = 0;
$.each(this.points, function() {
var reqpoint = this.point.index
s += '<br/>' + this.series.name + ': ' +
this.y.toFixed(2) + 'm';
if (this.series.index == 1) {
s += '<br/>Test Consum (l): ' + extraData[reqpoint] + 'm';
}
});
return s;
},

I have a series of points under a single series and I want the tooltip to display all the points in the series but my tooltip displays the top and bottom points selected and does not display the remaining points through the tool tip.How to fix this ?
http://jsfiddle.net/#&togetherjs=7IfUNtFkAE
In the above fiddle,I have the tooltip displaying values for the top and bottom points for apple series ,hovered over in the fiddle.How will i make it such that middle points are also displayed when i hover over them ?
As Paweł Fus pointed out in the comment, the data is not well prepared for highcharts.
So I have converted it from basic line chart to Scatter plot with line.

Original fiddle with highcharts usage issues
Add useHTML for tooltip when HTML formatting is in use.
shared is not needed and thus return statement of formatter is modified accordingly.
tooltip: {
useHTML: true,
formatter: function () {
return '<b>' + this.x + '</b><br/>' + 'fruit_id' + ': ' + this.point.fruit_id + '<br/>' + 'Values' + ': ' + this.point.y + '<br/>' + 'Mean' + ': ' + this.point.mean + '<br/>' + 'Median' + ': ' + this.point.median + '<br/>' + 'Min' + ': ' + this.point.min + '<br/>' + 'Max' + ': ' + this.point.max + '<br/>'
}
}
Original code contains Javascript problems (Unrelated to highcharts)
The series add data incorrectly as it is inside the loop.
Put this segment of code outside "for loop".
series.push({
data: data,
type: 'line',
color: '#000',
marker: {
symbol: 'circle'
},
showInLegend: false
});
I am using a stock chart to show trend data. On the backend I am getting what the valueSuffix should be (or valuePrefix as the case may be). I am also formatting the date display in the tooltip. Here is the important part of the series declaration:
...
name: 'Wages',
tooltip: {
valuePrefix: '$',
valueDecimals: 0
},
...
Here is the tooltip formatter:
...
tooltip: {
formatter: function () {
var s = '<b>';
if (Highcharts.dateFormat('%b', this.x) == 'Jan') {
s = s + 'Q1';
}
if (Highcharts.dateFormat('%b', this.x) == 'Apr') {
s = s + 'Q2';
}
if (Highcharts.dateFormat('%b', this.x) == 'Jul') {
s = s + 'Q3';
}
if (Highcharts.dateFormat('%b', this.x) == 'Oct') {
s = s + 'Q4';
}
s = s + ' ' + Highcharts.dateFormat('%Y', this.x) + '</b>';
$.each(this.points, function (i, point) {
s += '<br/><span style="color: ' + point.series.color + '">' + point.series.name + ':</span>' + point.y;
});
return s;
}
}
...
Example jsFiddle.
If you notice the prefix for the dollar sign is not showing on the Wage series. I am not really sure what I am missing here.
The fix is to break up the label formatting and the value formatting into distinct sections. See example jsFiddle.
Set the chart.tooltip like:
...
tooltip: {
headerFormat: '<b>{point.key}</b><br>',
xDateFormat: '%Q'
},
...
On the xAxis I replaced the label formatter with:
...
format: '{value: %Q}'
...
Inside the series I kept my suffix/prefix/decimals the same:
...
tooltip: {
valuePrefix: '$',
valueDecimals: 0
},
...
The big change came when I found that you can set your own date format label. I created one for Quarters (which is what I did the original cumbersome code for):
Highcharts.dateFormats = {
Q: function (timestamp) {
var date = new Date(timestamp);
var y = date.getFullYear();
var m = date.getMonth() + 1;
if (m <= 3) str = "Q1 " + y;
else if (m <= 6) str = "Q2 " + y;
else if (m <= 9) str = "Q3 " + y;
else str = "Q4 " + y;
return str;
}
};
I now get the tooltip to show the correct labels.
Unless something has changed in a recent version, you can't set your tooltip options within the series object. You can set anything that you would set in the plotOptions on the series level, but not the tooltip.
You can set a check within your main tooltip formatter to check for the series name, and apply the prefix accordingly.
{{edit::
This appears to be an issue of the formatter negating the valuePrefix setting.
Old question... but I spent hours looking for an acceptable way to do this.
/!\ : Before OP's answer...
If someone is looking for a way to use the formatter provided by highcharts (pointFormat attribute) (Doc here: LABELS AND STRING FORMATTING), you will find a (bad) example here :
http://jsfiddle.net/gh/get/jquery/1.7.2/highslide-software/highcharts.com/tree/master/samples/highcharts/tooltip/pointformat/
Why "bad" ? because if you change :
pointFormat: '{series.name}: <b>{point.y}</b><br/>',
with :
pointFormat: '{series.name}: <b>{point.y:,.1f}</b><br/>',
you add thousand separators (useless here) and force number format to 1 decimal ... and loose the suffix.
The answer is : series.options.tooltip.valueSuffix (or series.options.tooltip.valuePrefix)
Example :
pointFormat: '<span style="color:{series.color}">\u25CF</span> {series.name}: <b>{point.y:,.0f}{series.options.tooltip.valueSuffix}</b><br/>',
Hope this will save you some time.
Now OP's Answer :
Based on what I said, you can change :
$.each(this.points, function (i, point) {
s += '<br/><span style="color: ' + point.series.color + '">' + point.series.name + ':</span>' + point.y;
});
For this :
$.each(this.points, function (i, point) {
s += '<br/><span style="color: ' + point.series.color + '">'
+ point.series.name + ':</span>'
+ (typeof point.series.options.tooltip.valuePrefix !== "undefined" ?
point.series.options.tooltip.valuePrefix : '')
+ point.y
+ (typeof point.series.options.tooltip.valueSuffix !== "undefined" ?
point.series.options.tooltip.valueSuffix : '');
});
This will add prefix and/or suffix if they exists
