I've drawn a column chart with gradient Highcharts library .
that you can see here
$(function() {
$('#container').highcharts({
chart: {
type: 'column',
spacingBottom: 0,
spacingTop: 0,
spacingLeft: 0,
spacingRight: 0,
events: {
load: function() {
this.xAxis[0].setExtremes(0, 5);
}
}
},
title: {
text: ''
},
subtitle: {
text: ''
},
xAxis: {
categories: [
'S1',
'S2',
'S3',
],
crosshair: false,
gridLineWidth: 0,
tickWidth: 0
},
yAxis: {
min: 0,
max: 100,
title: {
text: ''
},
labels: {
enabled: false
},
gridLineWidth: 0,
},
plotOptions: {
column: {
pointPadding: 0.2,
borderWidth: 0
}
},
series: [{
name: 'S1',
data: [30, 50, 100],
color: {
linearGradient: {
x1: 0,
x2: 0,
y1: 0,
y2: 1
},
stops: [
[0, 'red'],
[1, 'green']
]
}
}]
});
});

The problem is about gradient ,
I have three bars here
the first column value is 30
the second is 50
and last is 100
but gradient is the same for all !
(all of the have green and red )
and it is not right !
I want a gradient in order that
the first column to be in green zoon
something like this
How can I achieve it ?
From docs:
Note that linear gradients can be differently defined (as an array or
an object). Also, start/end positions might be calculated differently
depending on the gradientUnits property (this property can only be set
in linear gradient declared as object).
gradientUnits values:
userSpaceOnUse Default when gradient declared as an array. Start and end positions have to be declared as pixels on the chart.
objectBoundingBox Default when gradient declared as an object. Start and end positions are in the range of 0 to 1 as described above.
Using this might sometimes result in the disappearance of the coloured
element.
So, instead of object for linearGradient, use array (which has values in pixels).
color: {
linearGradient: [0, 0, 0, 400],
stops: [
[0, 'red'],
[1, 'green']
]
}

I am using two xAxis and three yAxis in this example. As you can see the data labels for the two purple lines show as expected. But when you change the zoom level to anything more than 3m, the dataLabels hide.
I am using:
dataLabels: {
enabled: true,
allowOverlap: true,
align: 'left',
verticalAlign: 'top',
x: 0,
y: -18,
zIndex: 1000,
crop: false,
overflow: 'none',
inside: true,
padding: 0,
maxPadding: 0,
formatter: function() {
return 'Other';
}
}
for one, and just allowOverlap: true for the other. None of them seem to work. Any suggestions?
The issue is caused by dataGrouping, which group points when you set range above 3m. The solution is define formatter in plotOptions.series object, instead of point.
I have a little problem with my meteogram which I created in highchart. I have two x axises (on the top and on the bottom of my chart). I enabled scrollbar (I'm using highstock) and this scrollbar affected only on my bottom axis. When I move my scroll only bottom axis scrolls. I also want to move my top axis. How to do that? There is no 'scroll' option in reference to axis, only global:
scrollbar: {
enabled: true
}
Here you can see how it looks like:
Top categories doesn't change when we move scroll. Only bottom are changing.
Here is code resposible for x axises creation:
xAxis: [ {
categories: prepareCategories(jsonData),
min: 0,
max: 25,
tickInterval: 8,
tickWidth: 2,
plotLines: preparePlotLines(jsonData)
}, {
categories: prepareWindCategories(jsonData),
min: 0,
max: 25,
tickInterval: 2,
tickWidth: 2,
opposite: true,
labels: {
useHTML: true,
formatter: function() {
return prepareWindLabel(this.value.wind, this.value.windDirection);
}
}
} ],
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

I've this graph.
I only what to display integer steps on the y axis.
So instead of [0, 0.5, 1, 1.5, 2, 2.5] I want [0,1,2].
Is that possible? I'm not sure what to look for in the official API.
The answer you're looking for is the allowDecimals Boolean:
yAxis: {
allowDecimals : false,
/* completely irrelevant stuff follows... */
title: {
text: 'It\'s the y-axis'
},
plotLines: [{
value: 0,
width: 1,
color: '#808080'
}]
},
With allowDecimals: false.
yAxis: {
allowDecimals : true, // though it defaults to 'true' anyway...
/* other stuff... */
},
And the same graph with allowDecimals: true.

Highcharts API reference for allowDecimals.
