I want to have x axis labelled before drilling down but as soon as a user drills down the x axis labels should not be visible anymore. How can I implement?
Is it safe to assume that you have an afterSetExtremes event, like so?
xAxis:{
labels: {
enabled: true
},
events:{
afterSetExtremes:afterSetExtremes
},
.....
If so, inside of that function you could do the following:
function afterSetExtremes(){
$('#container').highcharts().xAxis[0].update({
labels:{
enabled: false
}
});
}
Here you can run my example. Hope it helps!
Highcharts.chart('container', {
chart:{
zoomType: 'x'
},
title: {
text: 'Zoom in on chart to hide xAxis labels'
},
xAxis: {
labels: {
enabled: true
},
events:{
afterSetExtremes:afterSetExtremes
}
},
series: [{
data: [29.9, 71.5, 106.4, 129.2, 144.0, 176.0, 135.6, 148.5, 216.4, 194.1, 95.6, 54.4]
}]
});
function afterSetExtremes(){
$('#container').highcharts().xAxis[0].update({
labels:{
enabled: false
}
});
}
#container {
height: 400px;
}

Use drilldown and drillup events:
const setLabelsVisibility = (chart, isVisible) => {
chart.xAxis[0].update({
labels: {
enabled: isVisible
}
}, false);
};
// Create the chart
Highcharts.chart('container', {
chart: {
type: 'column',
events: {
drilldown: function() {
setLabelsVisibility(this, false)
},
drillup: function() {
setLabelsVisibility(this, true)
}
}
},
...
});

I need to make a combination of draggable line chart and treemap.
See here: JSFiddle example
Highcharts.chart('container', {
series: [{
type: "treemap",
data: [
{id: "NS",name: 'NS_area', value:5},
// ...
}
},{
data: [[0, 100], [10,90.9], [20,81.8], [30,72.7]],
type: 'line',
}]
});
can I display x,y axis when using treemap? Do you have other idea how to combine both charts?
One workaround that might work for you is adding an additional axis and simply linking it to the original one.
For example, creating one "duplicate" x-axis and y-axis:
xAxis: [{
},{
linkedTo: 0
}],
yAxis: [{
}, {
linkedTo: 0
}]
See this JSFiddle demonstration of it in use. This makes the axis mimic the look you originally had.
If you want the line chart to be completely independent of the original axis, you could just do the following:
series: [{
// ...
}, {
data: [[0, 100], [10,90.9], [20,81.8], [30,72.7]],
type: 'line',
yAxis: 1,
xAxis: 1,
// ...
}],
xAxis: [{
},{
}],
yAxis: [{
}, {
}],
See this JSFiddle demonstration of it in use. This works as a completely separate axis.
I've started to use a graphic pretty similar to the dual combo axes. I've added the navigator from highstocks but the navigator graphic differs a lot from the graphic.
It seems that the navigator is plotting both series on the same column and I'm not capable of configuring both axis for it.
I'm trying to modify the jsfiddle example but I couldn't make it work:
series: [{
name: 'Rainfall',
type: 'column',
yAxis: 1,
data: [49.9, 71.5, 106.4, 129.2, 144.0, 176.0, 135.6, 148.5, 216.4, 194.1, 95.6, 54.4],
tooltip: {
valueSuffix: ' mm'
},
showInNavigator: true
}, {
name: 'Temperature',
type: 'spline',
data: [7.0, 6.9, 9.5, 14.5, 18.2, 21.5, 25.2, 26.5, 23.3, 18.3, 13.9, 9.6],
tooltip: {
valueSuffix: '°C'
},
showInNavigator: true
}]

Here's a workaround for the problem that ewolden pointed out:
I did not find a way to put each series on its own axis in the
navigator.
You can compute the ratio of the both y axes maximums and than update all the points in the second series using new values. That should mimic the presence of the second y axis.
chart: {
zoomType: 'x',
events: {
load: function() {
var chart = this,
navigator = chart.navigator,
ratio = chart.yAxis[0].getExtremes().max / chart.yAxis[1].getExtremes().max;
navigator.series[1].points.forEach(function(p) {
p.update({
y: p.y / ratio
});
}, false);
this.redraw();
}
}
}

You can add both graphs to the navigator using the following code:
navigatorOptions: {
type: 'column' //in the column series
}
And
navigatorOptions: {
type: 'line' //in the line series
}
That said, I did not find a way to put each series on its own axis in the navigator. Furthermore, highstock does not support xAxis categories, see API, highstock.xAxis only supports datetime format. So you will have to fill in timestamps and format them to show months if that is your desired output.

I'm trying to create a spider chart with a plot band that runs up against the outer edge of the circular border. Unfortunately, no matter what I try (yAxis max, yAxis maxPadding, plotBand thickness....) (tested in Firefox and Chrome), it ends up with some white space in between the yAxis max and the edge of the chart. I'm creating a bullseye pattern in my actual application, which looks fine except for the whitespace.
edit: the problem is not that I cannot fill in this whitespace (I can if I just increase the plotBand end to beyond the yAxis.max. The problem is that this area exists at all--I also want the last point to go up to the edge of the chart, so the inner plot bands are not shrunken to scale.
In this example, there's also whitespace in the middle of the circle--that's ok.

$(function () {

yAxis: {
plotBands: [{ // mark the weekend

What you need is configure tickInterval
javascript:
$(function () {
$('#container').highcharts({
chart: {
polar:true,
marginTop: 10
},
yAxis: {
plotBands: [{ // mark the weekend
color: '#FCFFC5',
from: 100,
to: 250,
}],
max:250,
tickInterval: 50,
startOnTick:true,
tickmarkPlacement:"on"
},
series: [{
data: [29.9, 71.5, 106.4, 129.2, 144.0, 176.0, 135.6, 148.5, 216.4],
pointStart: Date.UTC(2010, 0, 1),
pointInterval: 24 * 3600 * 1000
}]
});
});

If the endOnTick option is true, max will sometimes be rounded up. I updated your fiddle with endOnTick:false:

I am creating a HighChart with a plotLine in it. The plotLine has a fixed value, while the data can vary between charts.
HighChart scales the y-axis automatically based on the maximum value of data, but it doesn't consider the plotLine's value in its calculations.
Hence, if the data range encompasses the plotLine value, the plotLine gets shown, but gets cropped out of the viewport if not.
Example:
$(function () {
$(document).ready(function() {
var chart = new Highcharts.Chart({
chart: {
renderTo: 'container',
type: 'column'
},
title: {
text: 'Dummy Data by Region'
},
xAxis: {
categories: ['Africa', 'America', 'Asia']
},
yAxis: {
plotLines:[{
value:450,
color: '#ff0000',
width:2,
zIndex:4,
label:{text:'goal'}
}]
},
series: [{
name: 'Year 1800',
data: [107, 31, 650]
}]
});
});
});
JSFiddle for above code: http://jsfiddle.net/4R5HH/3/
The goal line (in red) is shown for the default data, but if I change the data to [107, 31, 250], then the plotLine goes out of the graph viewport and hence becomes invisible.
One other option that does not introduce data points:
yAxis: {
minRange:450,
min:0,
plotLines:[{
value:450,
color: '#ff0000',
width:2,
zIndex:4,
label:{text:'goal'}
}]
},
This sets the minimum for the yAxis to 0 (this is unlikely to be false in this case) and the minimum Range to 450.
See updated fiddle.
You need to add in a point to you chart but disable the marker.
I added a new series with scatter plot type and its value equal to the goal value:
{
name: 'Goal',
type: 'scatter',
marker: {
enabled: false
},
data: [450]
}
See updated jsFiddle: http://jsfiddle.net/wergeld/4R5HH/4/
In some cases, wergeld's solution would be preferable than jank's solution, especially when you are not sure about min and minRange. But wergeld's solution has a minor issue. If you point your mouse over the plot line, it will show a point and tooltip on the point. To avoid this, I have modified his solution and added enableMouseTracking to get rid of the problem.
{
name: 'Goal',
type: 'scatter',
marker: {
enabled: false
},
data: [450],
enableMouseTracking: false
}
See updated jsFiddle: http://jsfiddle.net/4R5HH/570/
You could simply set the max attribute to the max value you will have:
yAxis: {
max:650 //HERE
plotLines...
},
Adjust the axis while loading the chart:
$(function() {
$('#container').highcharts({
chart: {
events: {
load: function() {
var check = $('#container').highcharts();
var min = check.yAxis[0].min;
var max = check.yAxis[0].max;
var pLine = check.yAxis[0].chart.options.yAxis[0].plotLines[0].value;
if (pLine > max) {
check.yAxis[0].setExtremes(null, pLine);
}
if (pLine < min) {
check.yAxis[0].setExtremes(pLine, null);
}
}
}
},
xAxis: {
categories: ['Jan', 'Feb', 'Mar'],
},
yAxis: {
minPadding: 0.30,
plotLines: [{
color: '#FF0000',
width: 2,
value: 200
}]
},
series: [{
data: [70, 60, 95]
}]
});
});
