Is there a way to get a grand total of values in legend or any other place in pie charts? Here is the code with legend ,but instead of adding the total of percentage,i want to display the total of values..
$(function () {
var chart = new Highcharts.Chart({
chart: {
renderTo: 'container',
type: 'pie',
width: 500,
borderWidth: 2
},
title: {
text: 'demo'
},
credits: {
enabled: false
},
legend: {
layout: 'vertical',
align: 'right',
verticalAlign: 'top',
y: 30,
labelFormat: '{name} ({percentage:.1f}%)',
navigation: {
activeColor: '#3E576F',
animation: true,
arrowSize: 12,
inactiveColor: '#CCC',
style: {
fontWeight: 'bold',
color: '#333',
fontSize: '12px'
}
}
},
tooltip: {
formatter: function() {
return Highcharts.numberFormat(this.percentage, 2) + '%<br />' + '<b>' + this.point.name + '</b><br />Rs.: ' + Highcharts.numberFormat(this.y, 2);
}
},
series: [{
data: (function () {
var names = 'Ari,Bjartur,Bogi,Bragi,Dánjal,Dávur,Eli,Emil,Fróði,Hákun,Hanus,Hjalti,Ísakur,' +
'Johan,Jóhan,Julian,Kristian,Leon,Levi,Magnus,Martin,Mattias,Mikkjal,Nóa,Óli,Pauli,Petur,Rói,Sveinur,Teitur',
arr = [];
Highcharts.each(names.split(','), function (name) {
arr.push({
name: name,
y: Math.round(Math.random() * 100)
});
});
return arr;
}()),
showInLegend: true
}]
});
});

- I'm not sure I get this. The legend for Ari should be "Ari (57)"? – Halvor Holsten Strand Commented Aug 22, 2014 at 18:04
- legend can be in % but need to display the total value of all the slices somewhere on the chart – Mani Commented Aug 23, 2014 at 3:17
- You'd have to sum it in a variable then, from my knowledge. – Halvor Holsten Strand Commented Aug 23, 2014 at 4:21

- in the above link by Mark total is of percent value,here i am trying to get total of the values and not their percentage. – Mani Commented Aug 23, 2014 at 17:38

Reset to default 12I would use the Renderer.text to annotate the chart (and not do it in the legend since you have so many data points).
chart: {
events: {
load: function(event) {
var total = 0; // get total of data
for (var i = 0, len = this.series[0].yData.length; i < len; i++) {
total += this.series[0].yData[i];
}
var text = this.renderer.text(
'Total: ' + total,
this.plotLeft,
this.plotTop - 20
).attr({
zIndex: 5
}).add() // write it to the upper left hand corner
}
}
},
Fiddle example.
In addition to Mark's answer, to calculate the total, we do not need the for-loop statement. So, the code can be reduced.
chart: {
events: {
load: function(event) {
var total = this.series[0].data[0].total;
var text = this.renderer.text(
'Total: ' + total,
this.plotLeft,
this.plotTop - 20
).attr({
zIndex: 5
}).add() // write it to the upper left hand corner
}
}
},
