Disable click on datalabel in pie - highcharts

How do I disable click on a datalabel in a PIE?
In previous version 2.3.2 click on a datalabel doesn't have any action on the pie. How do I get that in version 3.0.4?

There is no strict way to get that behavior back, probably there were requests from users to make this work that way. However, you can disable this by overwriting 'click' event on dataLabels:
chart: {
events: {
load: function () {
var chart = this,
points = chart.series[0].data,
pLen = points.length;
for (var i = 0; i < pLen; i++) {
points[i].dataLabel.on('click', function (e) {
e.stopPropagation();
});
}
}
}
},
Working jsfiddle.

legendItemClick: function() {
return false;
}

set useHTML to false
$("#container").highcharts({
legend: {
useHTML: false
}
});

Changing the cursor in highcharts

I'd like the cursor to be a crosshair when it is over the chart area of a highcharts graph, to indicate to users that they can zoom in. However, I don't want the cursor to be a crosshair when it's over other areas such as the legend or axes.
Is this possible?
You can use built-in method chart.isInsidePlot(plotX, plotY). Example: http://jsfiddle.net/2eje4xxb/1/
Code example:
container.on("mousemove", function (event) {
var chart = container.highcharts();
if (chart.isInsidePlot(event.pageX - chart.plotLeft, event.pageY - chart.plotTop)) {
$("body").css({
cursor: "crosshair"
});
} else {
$("body").css({
cursor: "default"
});
}
});
Another idea is to utilize chart.plotBackgroundColor option, which creates rect, which can obtain CSS styles:
chart: {
zoomType: 'x',
plotBackgroundColor: "rgba(10,0,0,0)", // dummy color, to create an element
events: {
load: function(){
if(this.plotBackground) {
this.plotBackground.toFront().css({ // move on top to get all events
cursor: "crosshair"
});
}
}
}
},
And demo: http://jsfiddle.net/2eje4xxb/2/
Yes it is possible. You can write code to set the cursor style in the mouse events.
Please find the jsfiddle here - http://jsfiddle.net/3Lu7bzmn/5/
CSS
.cursorCrossHair{
cursor : crosshair
}
.cursorDefault{
cursor : default
}
JS - Shown only specific piece of code which is required to change the cursor. The id of the div used to render the highcharts is called "container". Please refer the jsfiddle to see the full working example.
$('#container').highcharts({
chart: {
plotOptions: {
series: {
point: {
events: {
mouseOver: function () {
$("#container").removeClass("cursorDefault").addClass("cursorCrossHair");
},
mouseOut: function () {
$("#container").removeClass("cursorCrossHair").addClass("cursorDefault");
}
}
}
}
},
});
});

How to change colors options in Highcharts programmatically?

In highcharts initialization I've set array of only one color. I would like to change this with another array on charts's hover event. In other words chart is default monochromatic and after hover it becomes colorful.
config = {
colors: ["#C0C0C0"]
};
chart = $('#chart').highcharts(config).highcharts()
$('#chart').hover(function(){
chart.options.colors = ["#E84C3D", "#C1392B", '#D25400', "#E67F22", "#F39C11"]
}, function(){
chart.options.colors = ["#C0C0C0"]
});
Unfortunately it doesn't work. How should I do it?
You can set the plotOptions events:
plotOptions: {
column:{colorByPoint:true},
series: {
animation:false,
events: {
mouseOver: function(e) {
//console.log( chart.options);
var options = chart.options;
if(options.colors[0]!='#E84C3D')
{
options.colors=['#E84C3D','#C1392B','#D25400','#E67F22','#F39C11'];
chart = new Highcharts.Chart(options);
}
},
mouseOut: function(e) {
var options = chart.options;
if(options.colors[0]!='#C0C0C0')
{
options.colors=['#C0C0C0'];
chart = new Highcharts.Chart(options);
}
}
}
}
}

Instad of creating chart multiple time, better is using series.update() and apply colors per bars.

Capture right click on column/bar

Highcharts upgraded their library to version 3. But in this version I can't capture the mouse's right click like before:
chart1 = new Highcharts.Chart({
chart: {
renderTo: 'container-chart-1',
zoomType: 'xy'
},
(...),
plotOptions: {
series: {
cursor: 'pointer',
point: {
events: {
click: function(e) {
alert('LEFT CLICK YEAH!');
},
contextmenu: function (e) {
alert('RIGHT CLICK NOT SO YEAH!');
}
}
}
}
}, (...)
I'm still on version 2 since I cannot make it to work.
Ideas and thoughts would be much appreciated?
It's interesting, I was sure that setting context menu in that way doesn't work since 1-2years. Now, possible way is to add custom events using Element.on(), for example:
for(var j in chart.series){
var series = chart.series[j];
for(var i in series.data){
(function(i){
var point = series.data[i];
if(point.graphic){
point.graphic.on('contextmenu', function(e){
// show your context menu
});
}
})(i)
}
}

Highcharts Pie chart return slice animation on mouseout

I am implementing an animated pie chart in Highcharts where the slices pull out on mouseover and all is good apart from a issue where the on mouseOut I want the slice to return to the 'closed' position.
This is the code for the animation and I have a clearTimeout on mouseOut however this is not returning the slice to the original position.
Is there an easy way of the chart to its original position.
I have a fiddle here...
http://jsfiddle.net/rupertito/Y3wvN/1/
pie: {
allowPointSelect: true,
stickyTracking: false,
point: {
events: {
legendItemClick: function() {
return false;
},
mouseOver: function(event) {
var point = this;
if (!point.selected) {
timeout = setTimeout(function () {
point.firePointEvent('click');
sectors.tooltip.refresh(point);
}, 20);
}
}
}
},
events: {
mouseOut: function() {
clearTimeout(timeout);
},
},
Hope this all makes sense and thanks for any help in advance.
Cheers
Rob
This is bug reported here. It's about not working slice for point. There is also workaround how avoid that issue. And simple example for you with mouseOver/mouseOut: http://jsfiddle.net/GqfU4/8/
function setTranslation(p, slice){
p.sliced = slice;
if(p.sliced){
p.graphic.animate(p.slicedTranslation);
} else {
p.graphic.animate({
translateX: 0,
translateY: 0
});
}
}
And for a pie:
point: {
events: {
mouseOut: function () {
setTranslation(this, false);
},
mouseOver: function() {
setTranslation(this, true);
}
}
},

Change zIndex in HighChart

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:
http://jsfiddle.net/G9d9H/9/
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
}
}
}
}
