I'm using highchart large tree map demo. I'm getting level data on click of each section. But also need to get the data on back button. So I'm using events drill up function to get data on click of back button. below is my code.
this.setState({
data: {
series: [{
type: 'treemap',
layoutAlgorithm: 'squarified',
allowDrillToNode: true,
animationLimit: 1000,
dataLabels: {
enabled: false
},
levelIsConstant: false,
levels: [{
level: 1,
dataLabels: {
enabled: true
},
borderWidth: 0,
}],
data: points,
events: {
click:(e)=>{
console.log(e)
},
drillup:(e)=>{
console.log(e)
}
}
}],
// subtitle: {
// text: 'Click points to drill down. Source: WHO.'
// },
title: {
text: ''
}
}
})
But don't know drill up is not working even click is working and also I added
import drilldown from "highcharts/modules/drilldown";
drilldown(Highcharts);
But still not getting any data. Please help.
Notice that treemap series don't use the drilldown module, but has own drilldown implementation, which logic you can find here: https://code.highcharts.com/modules/treemap.src.js
What you will need to do is render a custom button while clicking the point and attach an update functionality on this button. Something like here:
Demo: https://jsfiddle.net/BlackLabel/gas07t34/
events: {
click() {
let chart = this.chart;
chart.button = chart.renderer.button('back', 500, 0, function() {
chart.series[0].update({
data: data1
})
chart.button.destroy();
}).add()
this.update({
data: data2
})
}
}

I create a high chart using angular 4 and I want to highlight a particular portion of Highchart.
Ex Image :https://www.screencast.com/t/MHxo59j2dM
As per above image if data point value goes below to some limit (like 0) then highlight with "Red" color and if it goes below 8 then highlight with Yellow
I'm not sure whether its possible with Highchart or not but if someone had created this kind of features then please let me know.
Highchart provides Area Chart option - https://www.highcharts.com/demo/area-negative but my chart is normal and I don't want to highlight all series point.
There's no such functionality in Highcharts, but you can mimic it by using polygon series and plot lines:
var chart = Highcharts.chart('container', {
plotOptions: {
polygon: {
showInLegend: false
}
},
yAxis: {
tickInterval: 1,
plotLines: [{
value: 4,
color: 'orange',
width: 2
}, {
value: 3,
color: 'red',
width: 2
}]
},
series: [{
data: [6, 4, 3, 1, 2, 3, 4, 7]
}, {
type: 'polygon',
data: [[1,4], [2, 4], [2,3]],
color: 'orange'
}, {
type: 'polygon',
data: [[5,4], [6, 4], [5,3]],
color: 'orange'
}, {
type: 'polygon',
data: [[2,3], [5, 3], [4,2], [3,1], [2,3]],
color: 'red'
}]
});
Live working example: http://jsfiddle.net/kkulig/fbomb7cf/
It will require some programming to make the process of creating these areas automatic (in my fiddle everything is hard-coded).
To achieve similar styling you can try patter fill Highcharts plugin: https://www.highcharts.com/blog/extension/pattern-fill/

I was working on my chart,But it gives only single color for a name:vengadesh ,
Here is my Chart code in Fiddle..
My Example Chart in FIDDLE
But i want to get multiple colors for a single person dynamically...
My Actual Chart
MY EXPECTED CHART
Another solution is to set array of colors for series, then set colorByPoint: true, see: http://jsfiddle.net/7VNwk/2/
series: [{
type: 'column',
name: 'Vengadesh',
data: [2, 2, 2],
colors: ['blue', 'red', 'green'],
colorByPoint: true
}]
series: [{
type: 'column',
name: 'Member Average Packer Price',
data: [{y: 110.20, color: 'red'}, // this point is red
// default blue
{y: 110.20, color: '#aaff99'}, // this will be greenish
],
FIDDLE
I am attempting to make a stacked column chart representing events on a timeline. I need evenly-spaced bars, that scroll left/right with their respective ticks. Currently upon scrolling, the columns remain in place and their data is updated to reflect the new timespan they represent (I assume).
For example: when scrolling one "step" to the right, I note these differences:
The column remains in place with updated data and the axis tick moves to the left. This results in a 'graphic equalizer'-like effect when scrolling. (See fiddle)
What I need is to have the column represent the same data for the life of the chart, and to scroll left/right with its tick mark.
I suspect I'm misunderstanding something in the configuration. Any help/direction would be very much appreciated.
(As a side note: is there any easy way to style/color data from the past (with an xAxis datetime value of < today) differently to normal data?)
chart: {
alignTicks: false,
backgroundColor: '#eeeeee',
events: {
load: function (e) {
this.xAxis[0].setExtremes(1390943153305, 1400015153305);
}
},
ignoreHiddenSeries: true,
renderTo: $('#chart')[0]
},
colors: ['#89f1a4','#68d9f7','#9eb9ef','#c49eef'],
credits: {enabled: false},
legend: {
enabled: true,
shadow: true
},
rangeSelector: {selected: 1},
title: {text: 'Global Events'},
navigator: {
height: 40,
xAxis: {
gridLineWidth: 1
},
series: {type: 'column'}
},
plotOptions: {
series: {
showInLegend: true,
stacking: 'normal',
dataGrouping: {
enabled: true,
forced: true,
units: [
['millisecond', [604800000]], // Attempting to force data into weekly groups, throws error if this is null
['second', [604800]],
['minute', [10080]],
['hour', [168]],
['day', [7]],
['week', [1]], // Expected this to be the only required option if I only want weekly grouping...
['month', null],
['year', null]
]
}
}
},
xAxis: {ordinal: false},
series: data
If you want just weekly grouping, then only that one set, see: http://jsfiddle.net/s6BmC/2/
I think that resolves your issue, right?
plotOptions: {
series: {
showInLegend: true,
stacking: 'normal',
dataGrouping: {
enabled: true,
forced: true,
units: [ [ 'week', [1] ]]
}
}
},
Regarding additional question:
- yes you can set specific color for each point, but you need to determine on your own what color should be set:
data: [{ x: timestamp, y: value, color: color }, { x: timestamp, y: value, color: color }... ]
Another solution is to wrap setting color for column. Something similar I have done for candlestick: http://jsfiddle.net/79WZM/ (this solution requires much more knowledge of Highcharts).
I have building a pie chart using HighCharts library, and here is my chart:
// http://jsfiddle.net/t2MxW/20890/
var chart = new Highcharts.Chart({
colors: ['#0072BC', '#BFDAFF', '#DDDF00', '#24CBE5', '#64E572', '#FF9655', '#FFF263', '#6AF9C4'],
credits: { enabled: false },
chart: {
renderTo: 'container',
backgroundColor: 'rgba(255, 255, 255, 0.1)',
type: 'pie',
margin: [0, 0, 0, 0],
spacingTop: 0,
spacingBottom: 0,
spacingLeft: 0,
spacingRight: 0
},
title: { text: null },
plotOptions: {
pie: {
allowPointSelect: false,
size: '100%',
dataLabels: { enabled: false }
}
},
series: [{
showInLegend: false,
type: 'pie',
name: 'Pie Chart',
data: [
['Mobile', 65], // first half of pie
['Other', 35] // second half of pie
]
}]
});
But the problem is that I don't want appearing tooltip on mouse over...
Is it possible to disable tooltip on hover?
Disabling tooltip just disables the tooltip but the hover effect is still present. To disable the hover effect, add the following to your plotOptions:
plotOptions: {
series: {
states: {
hover: {
enabled: false
}
}
}
},
You need to set the tooltip attribute to false, like so:
tooltip: { enabled: false },
jsFiddle here
Here's the full code for your case:
var chart = new Highcharts.Chart({
colors: ['#0072BC', '#BFDAFF', '#DDDF00', '#24CBE5', '#64E572', '#FF9655', '#FFF263', '#6AF9C4'],
credits: { enabled: false },
tooltip: { enabled: false },
chart: {
renderTo: 'container',
backgroundColor: 'rgba(255, 255, 255, 0.1)',
type: 'pie',
margin: [0, 0, 0, 0],
spacingTop: 0,
spacingBottom: 0,
spacingLeft: 0,
spacingRight: 0
},
title: { text: null },
plotOptions: {
pie: {
allowPointSelect: false,
size: '100%',
dataLabels: { enabled: false }
}
},
series: [{
showInLegend: false,
type: 'pie',
name: 'Pie Chart',
data: [
['Mobile', 65], // first half of pie
['Other', 35] // second half of pie
]
}]
});
You might alternatively want to disable all mouse tracking in general, both tooltip and hover effects:
(copy and paste link) http://api.highcharts.com/highcharts#series.enableMouseTracking
http://jsfiddle.net/gh/get/jquery/1.7.2/highslide-software/highcharts.com/tree/master/samples/highcharts/plotoptions/series-enablemousetracking-false/
plotOptions: {
series: {
enableMouseTracking: false
}
}
The title of the question is about disabling hovering, so in case anyone else finds themselves here for that purpose, I'll elaborate on #SergeyB's answer.
There are a few options that affect how mouse hovering changes a series' styling. They each have different effects depending on the series type. I'll talk about line and pie series here, but generally, you can look under plotOptions.<seriesType>.states.hover for styling applied to the currently hovered series and plotOptions.<seriesType>.states.inactive for styling applied to the non-hovered series (e.g. plotOptions.pie.states.hover). None of these options affect the tooltip styling.
plotOptions.series.states.inactive
plotOptions.series.states.inactive affects the styling applied to all series that aren't currently being hovered over. To prevent them from fading into the background, set plotOptions.series.states.inactive.opacity to 1.
var chartOptions = {
// ...
plotOptions: {
series: {
states: {
inactive: {
opacity: 1,
},
},
},
},
}
jsFiddle for line
jsFiddle for pie
plotOptions.series.states.hover
plotOptions.series.states.hover affects the styling applied to the series that's being hovered over. For example, for a line series, the default is to thicken the line width and apply a halo to the nearest point.
To disable any styling of a currently hovered line series, set plotOptions.series.states.hover.enabled to false.
var chartOptions = {
// ...
chart: {
type: "line",
},
plotOptions: {
series: {
states: {
hover: {
enabled: false,
},
},
},
},
}
jsFiddle
Unfortunately, if we set this on a pie series, this will make the hovered slice fade into the background with the rest of the inactive slices (see this jsFiddle for an example). If we want to remove all hover styling without affecting the inactive styling, we can set plotOptions.series.states.hover.halo.size to 0 (which removes the halo) and plotOptions.pie.states.hover.brightness to 0 (which removes the brightening effect). Note that since brightness is specific to pie series, it's documented under plotOptions.pie instead of plotOptions.series (though it worked for me even when I added it under plotOptions.series).
var chartOptions = {
// ...
chart: {
type: "pie",
},
plotOptions: {
series: {
states: {
hover: {
halo: {
size: 0,
},
// this worked for me even though it's not
// documented under plotOptions.series:
//brightness: 0,
},
},
},
pie: {
states: {
hover: {
brightness: 0,
},
},
},
},
}
jsFiddle
plotOptions.series.stickyTracking
If you're using a line or area series, you may have noticed that as soon as you hover over the chart, even if you're not touching a series, the nearest series will receive hover styling and the rest will receive inactive styling. This is because plotOptions.series.stickyTracking is true by default for line and area series. If you set plotOptions.series.stickyTracking to false, hover and inactive styling will only be applied while you're hovering over a line.
var chartOptions = {
// ...
chart: {
type: "line",
},
plotOptions: {
series: {
stickyTracking: false,
},
},
}
jsFiddle
plotOptions.series.enableMouseTracking
As #ninedozen noted, you can completely disable all responsive interactions based on mouse movement by setting plotOptions.series.enableMouseTracking to false. Note that this will also disable tooltips in addition to hover/inactive styling.
Options scope
To apply these options to all series in the entire chart, place them under plotOptions.series. To apply them only to certain series types (or if the option is specific to a certain series), place them under plotOptions.<seriesType>. To apply them to a specific series, place them inside that series' options.
var chartOptions = {
series: [
{
name: "series1",
type: "line",
data: [...],
// these options will only apply to series1, not series2 or series3
states: {...},
},
{
name: "series2",
type: "line"
data: [...],
},
{
name: "series3",
type: "pie"
data: [...],
}
],
plotOptions: {
// these options will apply to all series in the chart
series: {states: {...}},
// these options will only apply to series of type line
// i.e. series1 and series2
line: {states: {...}}
}
}
You can simply turn them of using the following:
tooltip: {
enabled: false
},
plotOptions: {
series: {
states: {
inactive: {
opacity: 1,
},
},
}
}
I did this to display multiple line charts on hover.
In order to completely turn off tooltip and hover effects on a chart,
it is needed to turn off the tooltip, disable hover state and set inactive data opacity to 100%.
This answer is based on previous answers and shows a complete solution to the problem.
This is the configuration which turns off the hover and tooltip effects:
series: {
states: {
hover: {
enabled: false
},
inactive: {
opacity: 1,
}
}
},
tooltip: {
enabled: false
}
you can simply disable it by setting the option
tooltip:{
enabled: false
}
I usually just disable the style in css so I can still access the hover event in JS if needed...
.highcharts-tooltip {
display: none;
}
As specified in the accepted answer, you need to set
tooltip: { enabled: false }
Note - you must specify this as a property of your Highcharts.Options object (i.e. your chart options object, not a property of your series). So, either specify it in the JSON that you pass into your Highcharts.Chart object, or specify it as a property of a Highcharts.Options object that you explicitly create, before you pass it to you Highcharts.Chart
