High charts has double click event like?
plotOptions: {
series: {
cursor: 'pointer',
marker: {
radius: 2
},
point: {
events: {
// like this any event?If not, any alternative
dbclick: function () {
$('.highcharts-tooltip').show();
},
click: function () {
$('.highcharts-tooltip').show();
},
mouseOver: function () {
$('.highcharts-tooltip').hide();
},
mouseOut: function () {
$('.highcharts-tooltip').hide();
}
}
}
}
}
What i want to achieve is, i want to show tool tip on double click on point.
I tried using the extension, but it did not work, so I decided to write a small double click event (based on click event).
The downside is that it's encapsulated inside the 'click' event, but that's not a big issue since it calls a separate function.
First, define settings:
var doubleClicker = {
clickedOnce : false,
timer : null,
timeBetweenClicks : 400
};
Then define a 'double click reset' function in case the double click is not fast enough and a double click callback:
// call to reset double click timer
var resetDoubleClick = function() {
clearTimeout(doubleClicker.timer);
doubleClicker.timer = null;
doubleClicker.clickedOnce = false;
};
// the actual callback for a double-click event
var ondbclick = function(e, point) {
if (point && point.x) {
// Do something with point data
}
};
and in the highcharts settings of the chart:
series: [{
point: {
events: {
click: function(e) {
if (doubleClicker.clickedOnce === true && doubleClicker.timer) {
resetDoubleClick();
ondbclick(e, this);
} else {
doubleClicker.clickedOnce = true;
doubleClicker.timer = setTimeout(function(){
resetDoubleClick();
}, doubleClicker.timeBetweenClicks);
}
}
}
}
}]
You can use an extension, which allows do this.

I used the capture of the variable as a double click parameter. And when true I cleaned the doubleclick.
series: {
cursor: 'pointer',
point: {
events: {
click: function () {
if (clickdouble == ('Category: ' + this.category + ', value: ' + this.y)) {
alert('Category: ' + this.category + ', value: ' + this.y);
clickdouble = '';
}else{
clickdouble = 'Category: ' + this.category + ', value: ' + this.y;
}
}
}
}
}
It works for me.
You can add an ondblclick event listener at the container's dom element in which you have the chart. Currently highcharts doesn't seem to handle the event so the event will simply propagate to the container.

I'm using the small U.S. map in HighMaps and I want each state and it's datalabel to open up a new URL when clicked. I have the state working, but the label does not work.
this is what I tried:
plotOptions: {
series: {
allowPointSelect: true,
point: {
events: {
click: function(e) {
const url = e.target.point.value;
window.open(url);
}
}
},
datalabels: {
events: {
click: function(e) {
const url = e.target.point.value;
window.open(url);
}
}
}
}
},
Please see https://jsfiddle.net/sfjeld/zcsxobfa/12/ for the code.
Use the this.value instead of e.target.point.value:
plotOptions: {
series: {
point: {
events: {
click: function() {
const url = this.value;
window.open(url);
}
}
}
}
}
Demo:
https://jsfiddle.net/BlackLabel/6gpL57nf/
In your example, you could use:
e.point.properties.hasc
For get the value from the clicked point.
Code:
plotOptions: {
series: {
allowPointSelect: true,
point: {
events: {
click: function(e) {
const url = "https://www.google.com/search?q=" + e.point.properties.hasc;
window.open(url);
}
}
},
}
},
You can check other values using this path:
console.log(e.point.properties);
The full code is in this forked jsfiddle
plotOptions: {
series: {
events: {
afterAnimate: function () {
for (let item of this.chart.legend.allItems) {
item.legendItem.on('mouseover', function (e) {
/**
* Register a callback based on the legend selected
*/
}).on('mouseout', function (e) {
/**
* Degerister a callback
})
}
}
},
I wish to add functionality when I mouseover the legend item but the above removes the default transparency functionality. How can I easily re-invoke?
You can add a part of default code for the events functions:
plotOptions: {
series: {
events: {
afterAnimate: function() {
const legend = this.chart.legend,
boxWrapper = legend.chart.renderer.boxWrapper;
for (let item of legend.allItems) {
let isPoint = item instanceof Highcharts.Point,
activeClass = 'highcharts-legend-' +
(isPoint ? 'point' : 'series') + '-active';
item.legendItem.on('mouseover', function(e) {
if (item.visible) {
legend.allItems.forEach(function(inactiveItem) {
if (item !== inactiveItem) {
inactiveItem.setState('inactive', !isPoint);
}
});
}
item.setState('hover');
if (item.visible) {
boxWrapper.addClass(activeClass);
}
}).on('mouseout', function(e) {
legend.allItems.forEach(function(inactiveItem) {
if (item !== inactiveItem) {
inactiveItem.setState('', !isPoint);
}
});
boxWrapper.removeClass(activeClass);
item.setState();
})
}
}
}
}
}

I am using highchart contextmenu (using: https://blacklabel.github.io/custom_events/js/customEvents.js) and drill down and drill up.
Problem:
When I right click on pie chart we are able to call alert which is in contextmenu. At the same time, when I drill down and drill up then right click on pie chart, contextmenu is not working. In plotoption it's working fine but I do not need it in plotoption.
Code:
chart: {
type: 'pie',
events: {
drillup: function () {
var chart = this;
window['chart'] = chart;
setTimeout(function () {
console.log('drillup',chart.series[0].events);
if (!chart.plotOptions){
chart.plotOptions = {};
}
if (!chart.plotOptions.series) {
chart.plotOptions.series = {};
}
if (!chart.plotOptions.series.events) {
chart.plotOptions.series['events'] = {
contextmenu: function () {
alert('hi33')
}
}
}
/*
plotOptions: {
series: {
events: {
contextmenu: function () {
alert('hi33')
}
},
}
},
*/
console.log('drillup222',chart);
}, 100);
},
drilldown: function (e) {
var chart = this;
window['chart'] = chart;
setTimeout(function () {
if (!chart.series[0].events) {
chart.series[0]['events'] = {
contextmenu: function () {
alert('hi33')
}
}
}
console.log('drilldown',chart.series[0]);
}, 100);
}
}
},

The workaround for this issue is to add an event to plotOptions and check if event occurred on main series. Check demo and code posted below.
Code:
chart: {
type: 'pie',
events: {
load: function () {
var chart = this;
chart.series[0].customEventsEnabled = true;
}
}
},
plotOptions: {
series: {
events: {
contextmenu: function() {
var series = this;
if (series.customEventsEnabled || series.drilldownLevel) {
console.log('working');
}
}
}
}
}

using Highchart, how can we change the zIndex for a line according to its state, or dynamically from a click event ?
I tried :
plotOptions: {
series: {
states: {
select: {
lineWidth: 2,
zIndex:10
}
},
with : this.setState(this.state === 'select' ? '' : 'select'); in the Click event but it doesn't work.
Alright, it's definitely not pretty, but I couldn't find a way to actually set the zIndex, so I had to do some maneuvering to fake it and bring each series to the front in a certain order. Here's the snippet to include:
Highcharts.Series.prototype.setState = (function (func) {
return function () {
if (arguments.length>0){
if (arguments[0] !== ''){
if (typeof this.options.states[arguments[0]]['zIndex'] !== 'undefined'){
this.options.oldZIndex = this.group.zIndex;
this.group.zIndex = this.options.states[arguments[0]]['zIndex'];
}
}else{
if (typeof this.options['oldZIndex'] !== "undefined"){
this.group.zIndex = this.options['oldZIndex'];
}
}
var order = [], i = 0;
$.each(this.chart.series, function(){
order.push({id:i,zIndex:this.group.zIndex,me:this});
i++;
});
order.sort(function(a,b){return (a.zIndex>b.zIndex) ? 1 : -1;});
$.each(order, function(){
this.me.group.toFront();
});
func.apply(this, arguments);
}
};
} (Highcharts.Series.prototype.setState));
And here's the JSFiddle demonstrating:

Let me know if that's what you needed.
I think a better solution is to set the series.group.toFront() method on click (I prefer to use it on mouseover)
plotOptions: {
series: {
events: {
click: function () {
this.group.toFront();//bring series to front when hovered over
}
}
}
}
I'm using high stock API reference.
I want to know Where can I get the axis value when I click on a cursor?
Please help me!
If you use Highstock then you can get x value (time in miliseconds) and use Highcharts.dateFormat() which return data in appropriate format. (http://api.highcharts.com/highstock#highcharts.dateFormat())
http://jsfiddle.net/NX4KN/
plotOptions: {
series: {
cursor: 'pointer',
point: {
events: {
click: function () {
alert('Date: ' + Highcharts.dateFormat('%Y-%m-%d',this.x) + ', value: ' + this.y);
}
}
}
}
}
you can user series click event:
DEMO
series: {
cursor: 'pointer',
point: {
events: {
click: function() {
alert ('Category: '+ this.category +', value: '+ this.y);
}
}
}
}
