Hi I am trying bold the labels as per the attached image in the the code base with calculation with percentage as shown
https://codepen.io/SophTooke/pen/ExorZZj
[enter code here][2]
Try use dataLabels.formatter to edit dataLabels, and style inside CSS but remember to set dataLabels.useHTML.
plotOptions: {
sankey: {
dataLabels: {
useHTML: true,
formatter: function() {
let chart = this,
weight = chart.point.weight;
return `Weight: <span>${weight}</span>`
}
},
}
},

I want to use Accessible line chart of Highcharts (https://www.highcharts.com/demo/accessible-line)
In demo, I saw some series label position on last point, some in middle and first point.
How can I set all series label on last point?
Sorry for my bad English!
You can use data labels instead of series labels.
Example:
plotOptions: {
series: {
dataLabels: {
enabled: true,
formatter: function() {
if (this.point.index === this.series.points.length - 1) {
return this.series.name;
}
}
},
...
}
}

In my area chart I have three series which are presorted chronologically. This is what I am currently getting to display:
I'm using React which is why you see multiple renders, just ignore that. My dates that I am returning for the xAxis are in order but I'm only getting one. Why is that? Here is my code (using React Highcharts but it shouldn't matter I don't think):
xAxis: {
type: 'datetime',
labels: {
formatter: function() {
const dayStr = moment.unix(this.value).format('D');
const monthStr = moment.unix(this.value).format('M');
console.log(`${monthStr}/${dayStr}`, this.value);
return `${monthStr}/${dayStr}`;
},
align: 'left',
style: { "color": "#FFFFFF" }
},
title: {
text: 'Date',
style: { "color": "#FFFFFF" }
}
},
As you can see my formatter function is returning multiple dates but only one displays.
By default Highcharts algorithms decide which ticks to display (labels are drawn where the ticks are). Also some labels might be omitted when there's no enough space to place them.
Use tickPositions to force Highcharts to draw given ticks. You can also try tickPositioner to modify the ticks generated automatically.

I'm creating a bar chart with positive and negative values and display the xAxis (category name) of each data point (See Fiddle: https://jsfiddle.net/bej8j/75/).
Here's what I have for plot options but I'm not sure what else I need (Really only putting this code in here because I need to include some code to link to a jsfiddle)
plotOptions : {
series : {
dataLabels: {
formatter: function() {
return this.x
},
enabled: true
}
}
},
I'm trying to place the label so that it's aligned with the start of each bar on the chart. I photoshoped my desired result: http://i.imgur.com/0I1jSHW.png
Any help would be greatly appreciated.
You can iterate on each datalabel and use translate() function to move SVG element.
http://jsfiddle.net/eMjGg/7/
$.each(chart.series[0].data,function(i,data){
position = chart.yAxis[0].toPixels(0);
console.log(data);
if(data.y < 0)
position-=10;
else
position-=70;
data.dataLabel.attr({
x:position
});
});
I think this would help you: http://jsfiddle.net/42dRt/5/
Here's more info: high-charts datalabel position needs to change when value is too small
You must play with the X value:
plotOptions : {
series : {
dataLabels: {
formatter: function() {
return this.x
},
x: ?,
enabled: true
}
}
}
I have a custom chart here
I have set label property as
labels: {
formatter: function() {
return Highcharts.dateFormat('%Y', this.value);
},
align:'center',
x:150
}
I have a linked axis which shows year.
What I want is the axis label should be in center of the two extremes as in image.
what I have done now is, I have given x:150 to label.but that wont work if I resize the browser window.
Is there a way to do it?
Thanks in advance.
Here is the way I found it.
Instead of using static values,
I used useHTML, and positioned labels by CSS styles.
labels: {
useHTML:true,
formatter: function() {
return '<span class="label">'+Highcharts.dateFormat('%Y', this.value)+'</span>';
}
}
Simple example here
Is there a preferred way to eliminate or aggregate labels below a certain threshold when using HighCharts pie chart? I'd rather not have to rollup all values below a certain percentage into 'other' if I can. I've checked the docs and can't find anything. It would be very useful!
Thanks in anticipation.
The best way to achieve this is to use dataLabels formatter for pie chart like this:
plotOptions: {
pie: {
dataLabels: {
formatter: function(){
if (this.percentage < SOME_VALUE) return "";
return VALUE_TO_SHOW;
}
}
}
}
Replace SOME_VALUE and VALUE_TOSHOW with desired values. But there will be some problems if you're using connector for you labels (it is always visible).
A very late answer to this question:
If instead of returning empty string, you instead return null, the label AND connector will not show, and you'll be able to achieve this effect without removing the connector:
Example: jsfiddle
plotOptions: {
pie: {
dataLabels: {
formatter: function(){
if (this.percentage < SOME_VALUE) return null;
return VALUE_TO_SHOW;
}
}
}
}
