Disable legend hover in Highcharts - highcharts

I need to disable the hover attribute of legend items because I am using Highcharts on mobile platforms. Sadly, making a legendItemClick event does not solve the problem as hovering still occurs.
I was encouraged to see that this issue came up on the old support site for highcharts back in 2011. The thread can be found here. I was particularly glad to see the last jfiddle example and the function declared in it.
Unfortunately, the only thing that worked for me was the workaround of changing the setHoverStyle to null. This isn't great though since the hover action still fires and makes navigating the legend and chart unresponsive. The rest of the suggestions in the above thread resulted in the chart not being rendered.
Granted, it might be because I had a difficult time translating the example to my purposes - honestly, I do not know where to call the function and everywhere I have tried has failed. My JavaScript file is set up along the lines of
var chartDefinition = {
chart: {
renderTo: 'chart_content',
type: 'column'
},
colors: [
'#619ED6',
'#6BA547',
'#F7D027',
'#E48F1B',
'#B77EA3',
'#E64345',
'#60CEED',
'#9CF168',
'#F7EA4A',
'#FBC543',
'#FFC9ED',
'#E6696E'
],
title: {
text: ''
},
...
column: {
shadow: false,
borderWidth: 1,
events: {
click: function() { return false; },
legendItemClick: function() { return false; }
},
dataLabels: {
enabled: false,
color: '#222',
style: {
fontFamily: 'sans-serif',
fontSize: '13px',
fontWeight: 'bold'
}
}
}
},
series: []
};
Listing and setting the various highcharts attributes.
Does anyone know how to disable this hover attribute or where the proper place would be to call the function?

There are a few solutions to implement this. There's no built-in option to change that (as of 06.2022).
Try to disable mouseover for legendGroup, not legendItem.
Demo: http://jsfiddle.net/Cp7xh/10/
Disable pointer-events in CSS:
.highcharts-legend {
pointer-events: none;
}
Demo: http://jsfiddle.net/BlackLabel/ebrodhk4/
A plugin that prevents Highcharts Core from adding events:
Plugin:
(function(H) {
H.wrap(
H.Legend.prototype,
'init',
function(proceed, chart, options) {
if (options.enableMouseTracking === false) {
this.setItemEvents = false;
}
proceed.apply(this, [chart, options]);
}
);
})(Highcharts);
Usage:
legend: {
enableMouseTracking: false,
itemStyle: {
cursor: 'auto'
}
},

Highcharts datalabels are overlapping

I have a pretty busy chart that I need to clean up the overlapping datalabels on. I have tried all of the Highcharts options and previous forum answers I can find without much success. Here is my code on JSfiddle:
http://jsfiddle.net/cs4djfut/4/
plotOptions: {
column: { dataLabels: { allowOverlap: true, crop: false, overflow: 'none', enabled: true, formatter: function () { return this.series.name; } }, } },
Tried a function to change the datalabel position but it only worked on the fist datalabel.

Show only first and last xAxis label in Highcharts

I would like to display only the first and the last label on my xAxis. This would give enough of a »frame« for the user. However, I don't succeed in it. I am working with a synchronized chart, which can be found here. Is the second and third »column« of (smaller) graphs, I am targeting at.
I tried to work with »startOnTick« and »endOnTick«, but it won't do it.
xAxis: {
crosshair: true,
events: {
setExtremes: syncExtremes
},
visible: i === 1,
showFirstlabel: true,
showLastlabel: true,
startOnTick: true,
endOnTick: true,
labels: {
step: 500,
format: '{value}'
}
},
What is the correct way to force Highcharts to display only first and last label?
Here is a short fiddle (don't know why the line does not appear; it shows the values with mouseover...).
Thanks for any hints.
You can use the xAxis.labels.formatter callback to show wanted ticks:
Demo: https://jsfiddle.net/BlackLabel/m2Ln8sdg/
xAxis: {
tickAmount: 10,
labels: {
formatter() {
if(this.isFirst || this.isLast) {
return this.value
} else {
return ''
}
}
}
},
API: https://api.highcharts.com/highcharts/xAxis.labels.formatter
If you want to have more control about it (like hide label and tick) you can use the load callback method and proper logic to hide/show ticks:
Demo: https://jsfiddle.net/BlackLabel/fbcdskmv/
chart: {
events: {
load() {
let chart = this;
for (let i in chart.xAxis[0].ticks) {
//hide all
chart.xAxis[0].ticks[i].label.hide()
chart.xAxis[0].ticks[i].mark.hide()
// show first and last tick
if (chart.xAxis[0].ticks[i].isFirst || chart.xAxis[0].ticks[i].isLast) {
chart.xAxis[0].ticks[i].mark.show()
chart.xAxis[0].ticks[i].label.show()
}
}
}
}
API: https://api.highcharts.com/highcharts/chart.events.load
Or use the tickPositioner callback to achieve it: https://api.highcharts.com/highcharts/xAxis.tickPositioner
The above answers are good, but i just wanted to show another approach which works just fine.
In my styling i do this;
.highcharts-xaxis-labels > text:not(:first-child):not(:last-child) {
visibility: hidden !important;
}
Summing up #luftikus143 and #Sebastian Wędzel comments:
const data = [
['Jan 2020', 167],
['Feb 2020', 170],
['Mar 2020', 172]
];
xAxis: {
type: 'category',
tickPositions: [0, data.length - 1]
}
Will output only the first and last labels. #martinethyl's workaround answer might need some extra tweaks specially if you have multiple data points. Suggestions (might not work well with smaller media types):
xAxis: {
type: 'category',
labels: {
rotation: 0,
x: 5, // Optional: moves labels along the x-axis
style: {
textOverflow: 'none', // Removes ellipsis
whiteSpace: 'nowrap', // Gets the label text in one line
},
},

resize on load of highcharts in gridster widget

Found a couple of posts that came close to solving this. I'm loading a chart into a widget and it's not filling it, instead it's centered and extended past the widget - about only 1/3 of the pie chart shows for example.
I found the resize options for gridster and it gets me almost there... the same problem exists when I load the page, but when I resize the widget the chart fills it in perfectly.
I've tried aligning the chart, removing width and height settings, addeing resize and stop elements to gridsters..
var gridster = null;
$(document).ready(function () {
gridster = $(".gridster ul").gridster({
widget_base_dimensions: ['auto', 140],
autogenerate_stylesheet: true,
min_cols: 1,
max_cols: 6,
widget_margins: [5, 5],
resize: {
enabled: true,
resize: function (e, ui, $widget) {
Highcharts.charts[0].reflow(); // reflow the first chart...
},
stop: function(e, ui, $widget) {
Highcharts.charts[0].reflow(); // reflow the first chart...
}
}
}).data('gridster');
$('.gridster ul').css({'padding': '0'});
});
Highcharts.chart('container', {
chart: {
type: 'pie'
},
title: {
text: 'User data',
style: {"fontSize": "15px" , "color":"red"},
},
subtitle: {
text: 'Source: Click the slices to view categories.'
},
plotOptions: {
pie: {
showInLegend: false,
dataLabels: {
formatter: function(){
console.log(this);
if (this.percentage > 5)
return this.key + ': ' + this.y;
else
this.point.visible = false;
return '';
}
}
},
series: {
dataLabels: {
enabled: true,
}
}
},
tooltip: {
headerFormat: '<span style="font-size:11px">{series.name}</span><br>',
pointFormat: '{series.name}: <b>{point.percentage:.1f}%</b>'
},
when page loads the pie chart is sized to fit into the gridster widget.
Add one div wrapper around widget and add class which having height and width of that widget. It will render your highchart graph in that wrapper only.
<div class="size-1x1">
Render your graph code here
</div>
CSS:
.size-1x1 {
height:100px;
width: 120px;
}

D3.js tooltips not displaying correctlty when generated with Highcharts

I want to make some tooltips visible in my d3 map. The tooltips are column charts generated by Highcharts regarding the chosen city. The trick is that everything is displaying correctly (axis, labels ...) except that the columns are not visible!
Here my d3 code (only the relevant parts):
var tooltip = d3.select("body")
.append("div")
.attr("id","tooltip")
.style("position", "absolute")
.style("visibility", "hidden");
cities.on("mouseover", function(d, i) {
d3.select(this).style('fill', '#95a5a6');
tooltip.html(zoomCityComm(d))
return tooltip.style("visibility", "visible")})
.on("mousemove", function(d, i){
return tooltip.style("top", (d3.event.pageY - 130) + "px").style("left",(d3.event.pageX - 120) + "px");
})
}
The function zoomCityComm is HighCharts (example of data: [5,10]):
function zoomCityComm(d) {
chart = new Highcharts.Chart({
chart : {
renderTo: 'tooltip',
type: 'column',
width:200,
height:200,
plotBackgroundColor: '#FCFFC5',
zoomType: 'xy'
},
title: {
text: "TOTO"
},
legend: {
enabled: false
},
xAxis: {
categories: ['In','Out']
},
yAxis: {
title: {
text: 'Sum',
style: {
color: '#4572A7'
}
},
labels: {
style: {
color: '#4572A7'
}
},
},
series:[{color: '#4572A7',data: res}]
});
return document.getElementById("tooltip").innerHTML;
}
When the graph is displayed in a "normal" div within the document, it appears correctly.
Sorry if my explanations are not clear but ask me for some details if needed.
Thanks
Cyril
You're setting the HTML content of the div twice, as highcharts renders it itself. In your mouseover handler function, it is enough to do
zoomCityComm(d);
instead of
tooltip.html(zoomCityComm(d));
For the interested, here's what's happening. Setting the HTML of the tooltip div from the return value of the function captures the first animation frame that highchart uses to grow the bars. As it is the first frame, the height of the bars is still 0 -- that is, the bars are there, but not visible because they have essentially no height. Replacing the HTML of the div means that the animation won't work anymore, as the elements that would be animated have been replaced.

highchart not displaying bars chart while printing

I am new to highchart and am using it to render bar chart on my webpage. But the chart is not getting displayed while printing. Only the X and Y axis is printing with values but not the bars on it.
I am using IE8. The bar chart is visible(on print) in IE8 mode but its not visible in IE8 Compatible mode. I need to make it work on IE default mode i.e. IE8 compat. mode.
Can anyone help me in this issue.
I am adding a code chunk of my js function where I am printing my highchart in a lightbox window.
var chart = new Highcharts.Chart({
chart: {
renderTo: 'containerDivID',
type: 'column'
},
title: {
text: ''
},
xAxis: {
categories: xDataValues
},
yAxis: {
min: 0,
title: {
text: ''
}
},
tooltip: {
formatter: function() {
return ''+
this.x +': '+ this.y +' kr';
}
},
plotOptions: {
column: {
stacking: 'normal',
borderWidth: 1,
dataLabels: {
enabled: false,
color: (Highcharts.theme && Highcharts.theme.dataLabelsColor) || 'white'
}
}
}
,
yAxis: {
labels: {
formatter: function() {
return this.value;
}
},
title:{
text: ''
}
},
series: [
{
name: 'YAxis',
color: '#37789F',
data: yDataValues
}
],
credits:{
enabled: false
}
});
In this lightbox I have a print button on pressing this button I am calling window.print() to print the page. On my print page I can see the y and x axis and there data but cannot see my bar charts. But If I change IE8 mode from Compatible to IE8 standard mode then I can see my chart on printing.
Regards,
Andi
For me I didn't use the print() function to print the chart as I need to print extra data with the chart; As my chart is part of a report.
kindly find the custom print function I wrote:
function printReport() {
w = window.open();
var svg = myChart.getSVG();
//clone the div you want to print which contains your chart
var toprint = $('#bs-results') .clone();
//replace the chart with the svg
toprint.find('#graph_div').html(svg);
//right the output to print it
w.document.write(toprint.html());
w.print();
w.close();
}
Please take look at compatibility page http://www.highcharts.com/documentation/compatibility, we support native browser but not compatibility mode.
