Highcharts - Show tooltip on points click instead mouseover - highcharts

Question

Is it possible to have tool tip on clicking of points instead of mouse move.
I have tried with showing values in java script alert as below
plotOptions: {
series: {
cursor: 'pointer',
point: {
events: {
click: function() {
alert ('Category: '+ this.category +', value: '+ this.y);
}
}
}
}
}
Requirement is to show high chart tool tip on click.
Please help. Thanks!

As #PawelFus states, it's not officially supported but you can fudge this in by taking control of the visiblity of the tooltip.
First on chart load, hide it:
chart: {
events: {
load: function(){
$('.highcharts-tooltip').hide();
}
}
},
Disable sticky tracking, and on mouseout hide it, on click show it:
plotOptions: {
series: {
stickyTracking: false,
events: {
click: function() {
$('.highcharts-tooltip').show();
},
mouseOut: function() {
$('.highcharts-tooltip').hide();
}
}
}
},
Here's a fiddle example.
First attempt only worked in chrome, here's another:
Disable the default tooltip:
tooltip: {
enabled: false
},
In the chart load event, create your own:
chart: {
events: {
load: function(){
this.myTooltip = new Highcharts.Tooltip(this, this.options.tooltip);
}
}
},
In the click and mouseout control it:
plotOptions: {
series: {
stickyTracking: false,
events: {
click: function(evt) {
this.chart.myTooltip.refresh(evt.point, evt);
},
mouseOut: function() {
this.chart.myTooltip.hide();
}
}
}
},
I tested this in IE and Chrome, I won't install Firefox anymore.
Update to code 9/7/2017 with new stack snippet:
$(function () {
$('#container').highcharts({
xAxis: {
categories: ['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun',
'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec']
},
tooltip: {
valueSuffix: '°C',
enabled: false
},
chart: {
events: {
load: function(){
this.myTooltip = new Highcharts.Tooltip(this, this.options.tooltip);
}
}
},
plotOptions: {
series: {
stickyTracking: false,
events: {
click: function(evt) {
this.chart.myTooltip.options.enabled = true;
this.chart.myTooltip.refresh(evt.point, evt);
},
mouseOut: function() {
this.chart.myTooltip.hide();
this.chart.myTooltip.options.enabled = false;
}
}
}
},
series: [{
name: 'Tokyo',
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]
}]
});
});

Adding for those who have problems like me with useHTML: true and wants to display tooltip only on click and not on hover.
tooltip: {
useHTML: true
}
Here is a fiddle.

Answer 3

Just add for those who has the same problems as myself (see comment from #kevinandrada just after correct answer, i can't comment): if you call tooltip.refresh when your tooltip.shared = true you'll get an exception Uncaught TypeError: Cannot read property 'category' of undefined.
You should provide an array of points as a first argument:
plotOptions: {
series: {
stickyTracking: false,
events: {
click: function(evt) {
var points = this.chart.series.map(function(d) {
return d.searchPoint(evt, true)
});
this.chart.myTooltip.refresh(points, evt);
},
mouseOut: function() {
this.chart.myTooltip.hide();
}
}
}
},

The problem of first mouse-over tooltip showing in Alexandra Espichán excellent fiddle can be solved via css and the mouseover event omit by replacing his invisibility class with:
.highcharts-tooltip:not(.clone){
visibility: hidden !important;
}

Answer 5

Here is the fix for "Cannot read category of undefined". I just take hovered points of chart and pass them to refresh.
point: {
events: {
mouseOver: function(evt) {
var hoveredPoints = a.hoverPoints;
a.tooltip.refresh(hoveredPoints);
},
mouseOut: function() {
a.tooltip.hide();
}
}
}
