Click events on highcharts with multiple series
When I have multiple series that have intersecting points on my chart the click events don't seem to fire at all. Here is an example:
If you take a look at April where all 3 series intersect and try to click on the point it won't do the alert but if you check any of the points that don't intersect they alert properly.
$(function () {
$('#container').highcharts({
chart: {
zoomType: 'xy'
},
title: {
text: 'Average Monthly Weather Data for Tokyo'
},
subtitle: {
text: 'Source: WorldClimate.com'
},
xAxis: [{
categories: ['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun',
'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec']
}],
yAxis: [{ // Primary yAxis
labels: {
formatter: function() {
return this.value +'°C';
},
style: {
color: '#89A54E'
}
},
title: {
text: 'Temperature',
style: {
color: '#89A54E'
}
},
opposite: true
}, { // Secondary yAxis
gridLineWidth: 0,
title: {
text: 'Rainfall',
style: {
color: '#4572A7'
}
},
labels: {
formatter: function() {
return this.value +' mm';
},
style: {
color: '#4572A7'
}
}
}, { // Tertiary yAxis
gridLineWidth: 0,
title: {
text: 'Sea-Level Pressure',
style: {
color: '#AA4643'
}
},
labels: {
formatter: function() {
return this.value +' mb';
},
style: {
color: '#AA4643'
}
},
opposite: true
}],
tooltip: {
shared: true
},
legend: {
layout: 'vertical',
align: 'left',
x: 120,
verticalAlign: 'top',
y: 80,
floating: true,
backgroundColor: '#FFFFFF'
},
plotOptions:{
column:{
point:{
events:{
click:function(){
alert('aaa');
}
}
}
}
},
series: [{
name: 'Rainfall',
color: '#4572A7',
type: 'column',
yAxis: 1,
data: [49.9, 71.5, 106.4, 129.2, 144.0, 176.0, 135.6, 148.5, 216.4, 194.1, 95.6, 54.4],
tooltip: {
valueSuffix: ' mm'
}
}, {
name: 'Sea-Level Pressure',
type: 'spline',
color: '#AA4643',
yAxis: 2,
data: [1016, 1016, 1015.9, 1015.5, 1012.3, 1009.5, 1009.6, 1010.2, 1013.1, 1016.9, 1018.2, 1016.7],
marker: {
enabled: false
},
dashStyle: 'shortdot',
tooltip: {
valueSuffix: ' mb'
}
}, {
name: 'Temperature',
color: '#89A54E',
type: 'spline',
data: [7.0, 6.9, 9.5, 14.5, 18.2, 21.5, 25.2, 26.5, 23.3, 18.3, 13.9, 9.6],
tooltip: {
valueSuffix: ' °C'
},
index: 1,
zIndex: 99,
events: {
click: function(e) {
alert('boom');
console.log("CLICKY");
}
}
}]
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<script src="http://code.highcharts.com/highcharts.js"></script>
<script src="http://code.highcharts.com/modules/exporting.js"></script>
<div id="container" style="min-width: 400px; height: 400px; margin: 0 auto"></div>I've tried adding index/zIndex to give priority to certain points but it doesn't seem to help.

Came up with a nice solution for you. Because the individual line events were not reliable I created an event for any point on the graph that was clicked, and then used the event information to pull the name of the series and run a check to see if it is the one that I wanted.
Here is the Javascript that I added: http://jsfiddle.net/agnHV/24/
plotOptions: {
series: {
point: {
events: {
click: function(e){
var seriesName = e.point.series.name;
if(seriesName == "Temperature") {
console.log("Clicked Temperature Line");
}
else if(seriesName == "Sea-Level Pressure") {
console.log("Clicked Sea-Level Line");
}
else if(seriesName == "Rainfall") {
console.log("Clicked Rainfall Bar");
}
}
}
}
}
}
$(function () {
$('#container').highcharts({
chart: {
zoomType: 'xy'
},
title: {
text: 'Average Monthly Weather Data for Tokyo'
},
subtitle: {
text: 'Source: WorldClimate.com'
},
xAxis: [{
categories: ['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun',
'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec']
}],
yAxis: [{ // Primary yAxis
labels: {
formatter: function() {
return this.value +'°C';
},
style: {
color: '#89A54E'
}
},
title: {
text: 'Temperature',
style: {
color: '#89A54E'
}
},
opposite: true
}, { // Secondary yAxis
gridLineWidth: 0,
title: {
text: 'Rainfall',
style: {
color: '#4572A7'
}
},
labels: {
formatter: function() {
return this.value +' mm';
},
style: {
color: '#4572A7'
}
}
}, { // Tertiary yAxis
gridLineWidth: 0,
