I would like to have multiple series in my sankey diagram so that the legend adjusts along.
For now, I have to have to trick with an empty data series:
series: [{
name: 'New allocations',
keys: ['from', 'to', 'weight', 'color'],
data: sortedData,
centerInCategory: true,
showInLegend: true,
color: 'pink',
colorByPoint: false,
nodes,
}, {
name: 'Current allocations',
keys: ['from', 'to', 'weight', 'color'],
data: [], // Only added so that it is displayed in the legend :(
centerInCategory: true,
showInLegend: true,
color: 'blue',
colorByPoint: false,
nodes,
}]
But it doesn't feel correct for color handling, nor tooltip content.
Thanks
A possible solution would be to use hide() and show() methods, another thing is to set the color to transparent.
Unfortunately, I don't see an option to not have the whole date in the following series because otherwise the series is added to the whole width of the chart.
var series = chart.series[1];
if (series.visible) {
series.hide();
e.target.innerHTML = 'Show apples';
} else {
series.show();
e.target.innerHTML = 'Hide apples';
}

I am trying to create a lollipop chart where some values are negative, and some are positive, either side of zero, like this:
image
However the chart seemingly only allows the marker to be on the "high" end of the chart. Is there a way to control which end has the marker ?
I'm using these chart options:
chartOptions: {
chart: {
type: 'dumbbell',
inverted: true
},
title: {
text: 'lollipop chart'
},
xAxis: {
type: 'category'
},
yAxis: {
title: {
text: 'value'
}
},
series: [{
name: 'value',
data: [{
name: 'a',
low:0,
high:13,
}, {
name: 'b',
low:0,
high:26,
},{
name: 'c',
low:-43,
high:0
},{
name: 'd',
low:-83,
high:0
},{
name: 'e',
low:0,
high:113
}]
}]
}
The series which should be used in this case is a lollipop, but it seems that the array of objects configuration doesn't work. I reported it on the Highcharts Github issue channel, where you can follow this thread: https://github.com/highcharts/highcharts/issues/13202
As a solution in the dumbell series I suggest to find those graphics in the render callback and hide them.
Demo: https://jsfiddle.net/BlackLabel/3o7acsbt/
events: {
render() {
let chart = this;
chart.series[0].points.forEach(p => {
if (p.low >= 0){
p.lowerGraphic.hide()
} else {
p.upperGraphic.hide()
}
})
}
}

EDIT
Under the GitHub link, the workaround showed up. Please check it, maybe will be fit better to your requirement.
I'd like to show two sets of Venn diagrams inside a single chart. So I have the following code for sets A and B:
Highcharts.chart('container', {
series: [{
type: 'venn',
data: [{
sets: ['A1'],
value: 188956
}, {
sets: ['A2'],
value: 211267
}, {
sets: ['A1', 'A2'],
value: 23085,
name: "overlap"
}, {
sets: ['B1'],
value: 10880
}, {
sets: ['B2'],
value: 10880
}, {
sets: ['B1', 'B2'],
value: 6389,
name: "overlap"
}]
}],
title: {
text: 'Sets A and B'
}
});
What's really nice about showing everything together is that the four circles are sized proportionately to each other. The problem is how they're laid out. I'd want to show set B on the right side of A with some spacing between them. I also want set B to be laid out horizontally like A is.
Is this doable and if so how?
Thanks!

That is not possible in one chart, but you can create multiple charts:
Highcharts.chart('container', {
...,
series: [{
type: 'venn',
data: [...]
}]
});
Highcharts.chart('container2', {
...,
series: [{
type: 'venn',
data: [...]
}]
});

I am trying to plot a chart with only two data points from a CSV file that holds many more data points with a datetime x-Axis.
In the end the user should be able to compare two years of his choice out of the whole dataset.
From the API documentation I know that I can pick a range of data points from a CSV with startRow and endRow:
https://api.highcharts.com/highcharts/data.startRow
But that would only plot one specific point, as you can see in my fiddle.
Is there any other way to programmatically show specific points?
Highcharts.chart('container', {
chart: {
type: 'column',
polar: false,
},
title: {
text: ''
},
subtitle: {
text: ''
},
data: {
csv: document.getElementById('csv').innerHTML,
startRow: 3,
endRow: 4,
googleSpreadsheetKey: false,
googleSpreadsheetWorksheet: false
},
series: [{
name: 'val'
}],
yAxis: [{
title: {
text: ''
},
opposite: true,
labels: {
align: 'right',
reserveSpace: true
}
}],
xAxis: [{
type: 'datetime',
opposite: false
}],
pane: {
background: []
},
responsive: {
rules: []
},
legend: {
title: ''
},
plotOptions: {
series: {
animation: false
}
}
});
Edit:
I forgot to mention, that i only want to load the CSV once. After that the user should be able to select/update data points without reloading the data.
For showing ranges of values dynamically, I used Axis min and max settings like this:
$(this).highcharts().update({
xAxis:{
min: Date.UTC(selectedStart,0,0),
max: Date.UTC(selectedEnd,11,31)
}
});
The whole dataset is loaded once and the chart axis gets updated on user interaction.
Now I am looking for something similar just not for a range but a comparison of two values off of the whole dataset.
Highcharts data module provides a function called parsed that allows you to modify the fetched data programmatically before it's applied to the chart.
From Highcharts API (https://api.highcharts.com/highcharts/data.parsed):
parsed: function
A callback function to access the parsed columns, the
two-dimentional input data array directly, before they are
interpreted into series data and categories. Return false to stop
completion, or call this.complete() to continue async.

I'm using HighCharts, I have this array,
I would like to create a chart like this:
As I know, the format of series is like this:
series:[{
name: 'Production',
data: [0.074, 0.040,0.034,0.036,0.068]
}, {
name: 'Reprise',
data: [0.024,0.022,0.029, 0.055, 0.052]
}]
with categories array:
['Mario', 'Andre', 'Jean Jacques', 'Fidy', 'Judith']
How could I do if I want to paste each value of column Volumes to each Production Stacked Bar value like the chart above ?
Thanks!
you can see an example here: http://jsfiddle.net/gh/get/jquery/1.9.1/highslide-software/highcharts.com/tree/master/samples/highcharts/demo/column-stacked/
series: [{
name: 'Volume',
data: [1, 0.16, 0.46, 0.37, 0.24]
}, {
name: 'Reprise',
data: [0.024, 0.0.....]
}, {
name: 'Production',
data: [....]
}]
Later edit: to display volume as data label you can use the formatter function:
column: {
stacking: 'normal',
dataLabels: {
formatter: function () {
return this.x;//you can have a little logic here if (thix.x == 'Production) return myVariable[y];myVariable will contains values from volume or something similar
}
}
}
Define volume in your data array:
data: [{y:0.074,volume:1}, {y:0.040,volume:0.15}]
And use formatter in datalabels options to get custom value:
formatter: function () {
return this.point.volume + ' km';
}

I made a barchart with dates. Currently, to remove the dates, you must click on the dates in the legend. I wish delete multiple dates at once.
Let's take an example. My dates range from 1960 to 2015. If I would have on my chart the dates from 2000 to 2005, so I would like that if you click on 1960 and 1999, then all the dates between are deleted / hidden. It goes faster when many dates.
How to do ?
Here is my code :
$(function () {
$('#container').highcharts({
chart: {
type: 'column'
},
colors:[
'#7cb5ec',
'#434348',
'#90ed7d',
'#f7a35c',
'#8085e9',
'#f15c80',
'#e4d354',
'#2b908f',
'#f45b5b',
'#91e8e1',
'#DA70D6',
'#1E90FF',
'#E0F000'
],
legend:{
itemStyle:{
fontSize:'10px',
font:'10pt',
color:'#000000'
}
},
title:{
style:{
fontSize:'0px'
}
},
subtitle:{
style:{
fontSize:'0px'
}
},
xAxis: {
categories: [
'',
],
},
yAxis: {
min: 15,
title: {
text: 'Number',
style:{
fontSize:'0px'
}
}
},
tooltip: {
shared: false,
useHTML: true
},
plotOptions: {
column: {
pointPadding: 0.2,
borderWidth: 0
}
},
series: [{
name: '2004',
data: [49.9],
},
{
name: '2005',
data: [83.6]
},
{
name: '2006',
data: [48.9]
},
{
name: '2007',
data: [69.1]
},
{
name: '2008',
data: [83.6]
},
{
name: '2009',
data: [40.9]
},
{
name: '2010',
data: [69.9]
},
{
name: '2011',
data: [83]
},
{
name: '2012',
data: [28.9]
},
{
name: '2013',
data: [40.9]
},
{
name: '2014',
data: [81.6]
},
{
name: '2015',
data: [24.9]
},
{
name: '2016',
data: [46.4]
}]
});
});

Rather than having each year as its own series, I would recommend that you place the years as the values in your x-axis (as categories) and then use Highcharts' native zoom function to allow users to select a certain date range.
I've updated your fiddle with some changes, which I explain below: https://jsfiddle.net/brightmatrix/hr28s27L/
First, in your chart option, I added zoomType: 'x' to allow users to use their mouse to zoom in on specific years. The value x means they can only zoom horizontally (across), which makes for a "cleaner" interaction.
chart: {
type: 'column',
zoomType: 'x'
},
Second, I updated your x-axis with the years as the categories/values:
xAxis: {
categories: ['2004','2005','2006','2007','2008','2009','2010','2011','2012','2013','2014','2015','2016']
},
Lastly, I updated your series to show just the data points, which are then plotted on the y-axis:
series: [{
name: 'data by year',
data: [49.9,83.6,48.9,69.1,83.6,40.9,69.9,83,28.9,40.9,81.6,24.9,46.4]
}]
Here is what happens when a user clicks and drags their mouse cursor:
The shaded box is what they are selecting. Once they release the cursor, the chart will automatically adjust to show only what they chose. A "Reset Zoom" button will appear at the top right to allow them to go back to all years:
Update (July 19, 2016): I did some research on adding a simple slider element to this chart that allows users to choose from a range of years.
An updated version of my fiddle that shows this example chart with sliders can be found here: https://jsfiddle.net/brightmatrix/uvat8u05/.
The code to handle the sliders is shown below. I discovered that explicitly setting the slider values to integers using the parseInt() function solved a couple of problems:
You can correctly compare the slider values to make sure users can't choose an end year that is earlier than the start year.
The setExtremes() function correctly shows a single year when users choose the same start and end year.
All x-axis labels are shown at all times. Before I added parseInt(), some labels disappeared when users chose different values in the sliders.
Please be sure to read the comments I've left in both the HTML and Javascript panes, as I've included additional details on why I made certain code decisions.
// on change handler for both sliders
$('.mySlider').bind('change', function(e) {
e.preventDefault();
var chart = $('#container').highcharts();
// convert the slider values to integers to make sure setExtremes() works as expected
var slider1Val = parseInt($('input[name="slider1"]').val());
var slider2Val = parseInt($('input[name="slider2"]').val());
if (slider2Val < slider1Val) {
// warn the user if they try to choose an end year that is later than the start year
alert("You can't choose an end year that is earlier than your start year.");
} else {
// use setExtremes to set the x-axis ranges based on the values in the sliders
chart.xAxis[0].setExtremes(slider1Val, slider2Val);
}
});
I hope this information is helpful for you.
