Using tooltip formatter we can display both the series name and value but when same is done using the plotoptions event mouseover am not able to get the series name and value
Tooltip: formatter
PlotOption:Mousover
mouseOver: function () {
$.each(this, function (i, e) {
$reporting.html('x: ' + this.x + 'Category: ' + this.series.name + ', y: ' +Highcharts.numberFormat(Math.abs(this.y)));
});
}
Example of using it in mouseover
mouseOver: function () {
console.log(this);
var series = this.series.chart.series,
x = this.x,
y = this.y,
output = 'x: ' + x + 'y: ' + Highcharts.numberFormat(Math.abs(y));
//loop each serie
$.each(series, function (i, e) {
output += ' Category: ' + this.name;
if(i>0) {
$.each(series[i].data,function(j,point){
if(point.x === x) {
output += ' y: ' + Highcharts.numberFormat(Math.abs(y));
}
});
}
});
$reporting.html(output);
}
}
},

I got some problem with Highcharts transition between 9.x and 10.x version. I can't get color of series inside function in tooltip formatter.
tooltip: {
formatter: function () {
return this.points.reduce(function (s, point) {
return s + '<br/>' + "<span style='color:" + point.series.color + "'>\u25CF</span> " + point.series.name + ': ' +
point.y + 'm';
}, '<b>' + this.x + '</b>');
},
...
This is related to Belchertown weewx's skin issue.
Please have a look to that FIDDLE
Thanks.

Thank you for reporting this behaviour! I've created a github issue, that you can track here: https://github.com/highcharts/highcharts/issues/17627
Use another quotation marks configuration to achieve the correct tooltip format:
formatter: function () {
return this.points.reduce(function (s, point) {
return s + '<br/>' + '<span style="color:' + point.series.color + '">\u25CF</span>' + point.series.name + ': ' +
point.y + 'm';
}, '<b>' + this.x + '</b>');
},

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;
},

Specifically, the part which needs filling in is
'tooltip': {
'formatter': function(){
var output = '<strong>' + this.y + '</strong>';
var sorted = this.points.sort(function(a, b){
if (a.y == b.y){
return 0;
}
return a.y < b.y ? 1 : -1;
});
sorted.forEach(function(point, index){
var marker = '';
/*
TODO: How do I determine what symbol is used for the marker?
*/
output += '<br /><span style="color: ' + point.series.color + '">' + marker + '</span> ' + point.series.name + ': ' + point.y;
});
return output;
},
'shared': true
}
I have a line chart with a number of series. On mouseover, the tooltip displays all the values of all of them, in sorted order. This part is done and can be seen in the JSFiddle. My question is, I want each the text for each series in the tooltip to include the marker symbol used for that series, styled in the color of the series. The color styling is also complete and can be seen in the JSFiddle, but how do I get the marker symbol?
Modifying form earlier Answer it is for individual series tooltip. Here modified to shared tooltip
Fiddle demo
Highcharts.chart('container', {
'title': {
'text': 'Random Chart'
},
'tooltip': {
'formatter': function(){
var output = '<strong>' + this.y + '</strong>';
var sorted = this.points.sort(function(a, b){
if (a.y == b.y){
return 0;
}
return a.y < b.y ? 1 : -1;
});
sorted.forEach(function(point, index){
var marker = '';
if ( point.point.graphic && point.point.graphic.symbolName ) {
switch ( point.point.graphic.symbolName ) {
case 'circle':
marker = '●';
break;
case 'diamond':
marker = '♦';
break;
case 'square':
marker = '■';
break;
case 'triangle':
marker = '▲';
break;
case 'triangle-down':
marker = '▼';
break;
}
}
/*

*/
output += '<br /><span style="color: ' + point.series.color + '">' + marker + '</span> ' + point.series.name + ': ' + point.y;
});
return output;
},
'shared': true
},
'series': [{
'name': 'Series 1',
'data': [1, 3, 7, 19, 11, 27, 8, 15]
}, {
'name': 'Series 2',
'data': [2, 1, 8, 12, 14, 20, 9, 10]

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
}]
});
});

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
