I'm creating a pie chart in highcharts.
Does anybody know how to set data labels in two lines?
I'm finding this problem when the data labels are too long.
http://jsfiddle.net/larrytron/fSjnD/
$(function () {
$('#container').highcharts({
chart: {
plotBackgroundColor: null,
plotBorderWidth: null,
plotShadow: false
},
title: {
text: 'Browser market shares at a specific website, 2010'
},
tooltip: {
pointFormat: '{series.name}: <b>{point.percentage:.1f}%</b>'
},
plotOptions: {
pie: {
allowPointSelect: true,
cursor: 'pointer',
dataLabels: {
enabled: true,
color: '#000000',
maxStaggerLines:1,
connectorColor: '#000000',
format: '<b>{point.name}</b>: {point.percentage:.1f} %'
},
}
},
series: [{
type: 'pie',
name: 'Browser share',
data: [
['Firefox jandler glander gramenauer gramen', 45.0],
['IE', 26.8],
{
name: 'Chrome',
y: 12.8,
sliced: true,
selected: true
},
['Safari', 8.5],
['Opera', 6.2],
['Others', 0.7]
]
}]
});
});
You can simply set width for dataLabels, see: http://jsfiddle.net/Fusher/fSjnD/1/
style: {
width: '100px'
}
You can simply insert in the data labels:
data: [
['Firefox jandler glander <br><b>gramenauer gramen</b>', 45.0],
Note, for some reason, the second line loses the bold formatting unless you addit back in using tags.

Hello! I have problem with color in highchart library. I define class name of color inside data series. Class apply only to pie path but does not apply for legend. Ноw define color as class inside data series for all elements inside chart
Highcharts.chart('lvl-chart', {
chart: {
type: 'pie'
},
title: {
text: 'Fruit Consumption'
},
legend: {
align: 'left',
verticalAlign: 'top',
layout: 'vertical',
x: 0,
y: 100
},
plotOptions: {
pie: {
cursor: 'pointer',
dataLabels: {
enabled: false
},
showInLegend: true
}
},
series: [{
name: 'Brands',
data: [{
name: 'Chrome',
className:'emergency',
y: 61.41,
}, {
name: 'Internet Explorer',
className:'emergency',
y: 11.84
}, {
name: 'Firefox',
className:'emergency',
y: 10.85
}, {
name: 'Edge',
className:'emergency',
y: 4.67
}, {
name: 'Safari',
className:'emergency',
y: 4.18
}, {
name: 'Other',
className:'emergency',
y: 7.05,
}]
}]
});
.emergency{
background-color: #FF6347;
fill: #FF6347;
}
<div id="lvl-chart" style="width:100%; height:400px;"></div>
<script src="https://code.highcharts.com/highcharts.src.js"></script>
Do you need to use the className? You should be able to achieve it by defining the plotOptions.pie.colors array.
plotOptions: {
pie: {
cursor: 'pointer',
dataLabels: {
enabled: false
},
showInLegend: true,
colors: ['#FF6347']
}
},

API: https://api.highcharts.com/highcharts/plotOptions.pie.colors
EDIT
To update the legend items colors to the same as the point has assigned via CSS you need to enable the styledMode in the chart.

Because some date are overlap, I want to add labelline in each Bubble, How can I do that? Thks
You can add the label option to your series object:
series: [{
type: 'scatter',
symbolSize: function (data) {
...
},
emphasis: {
...
},
label: {
show: true,
position: 'top'
},
itemStyle: {
...
},
...
}]
all the customizations available for this label are here (position, format, etc):
https://echarts.apache.org/en/option.html#series-scatter.label
In the example below the y-axis crosses at 1, rather than 0. Is there a way to achieve this in echarts?
It seems to me, literally, you can't do this with basic bar chart because it will break the coordinate system and result will be anything but not a bar chart.
If you need only visual like on attached picture then you can hide xAxis and draw its surrogate with markLine but you will have the troubles with bar positioning (that will fix with stack and transparent bars, see below).
If you need real chart with responsive, zoomable and other opts then in the Echarts you can use custom series for build own chart type (see example).
Example how to make picture like attached:
var myChart = echarts.init(document.getElementById('main'));
var option = {
tooltip: {},
xAxis: {
data: ['Category-1', 'Category-2', 'Category-3', 'Category-4'],
show: true,
axisLine: {
show: true,
lineStyle: {
opacity: 0
}
},
axisTick: {
show: false,
}
},
yAxis: {
max: 4,
min: -1
},
series: [{
name: 'Series-1',
type: 'bar',
stack: 'group',
data: [1, 1, -3],
color: 'rgba(0,0,0, 0)',
}, {
name: 'Series-2',
type: 'bar',
stack: 'group',
data: [{
value: 1,
itemStyle: {
color: 'red'
}
}, {
value: 2,
itemStyle: {
color: 'green'
}
}, {
value: 1,
itemStyle: {
color: 'orange'
}
}],
markLine: {
symbol: "none",
data: [{
silent: false,
yAxis: 1,
lineStyle: {
color: "#000",
width: 1,
type: "solid"
}
}, ],
label: {
show: false,
}
},
}]
};
myChart.setOption(option);
<script src="https://cdn.jsdelivr.net/npm/echarts#4.8.0/dist/echarts.min.js"></script>
<div id="main" style="width: 600px;height:400px;"></div>
P.S. If this not a secret, why you need it?
So I have a chart.js chart with two series. One is a bar chart and the other is a line graph.
S1 = 71,166,2,6,8
S2 = 6,2,4,8,5
When I plot them, they both appear on their own scales which makes the bar and line graphs kinda pointless.
I need a way to plot both charts on the same scale.
Is there a way to do this within chart.js? If not, how would you do it?
thanks.
var barChartData = {
labels: dataLabels,
datasets: [{
type: 'bar',
label: "Actual",
data: dataActual,
fill: false,
backgroundColor: '#71B37C',
borderColor: '#71B37C',
hoverBackgroundColor: '#71B37C',
hoverBorderColor: '#71B37C',
yAxisID: 'y-axis-2'
}, {
label: "Maximum",
type:'line',
data: dataMaximum,
fill: false,
borderColor: '#EC932F',
backgroundColor: '#EC932F',
pointBorderColor: '#EC932F',
pointBackgroundColor: '#EC932F',
pointHoverBackgroundColor: '#EC932F',
pointHoverBorderColor: '#EC932F',
yAxisID: 'y-axis-1'
} ]
};
$(function () {
if (theChart !== undefined) {
theChart.destroy();
}
var ctxActualVsMax = document.getElementById("myChart2").getContext("2d");
theChart = new Chart(ctxActualVsMax, {
type: 'bar',
data: barChartData,
options: {
responsive: true,
tooltips: {
mode: 'label'
},
elements: {
line: {
fill: false
}
},
scales: {
xAxes: [{
display: true,
gridLines: {
display: false
},
labels: {
show: true,
}
}],
yAxes: [{
type: "linear",
display: true,
position: "left",
id: "y-axis-1",
gridLines:{
display: false
},
labels: {
show:true,
}
}, {
type: "linear",
display: false,
position: "right",
id: "y-axis-2",
gridLines:{
display: false
},
labels: {
show:true,
}
}]
}
}
});
});
In your code you have specified your two datasets to use different yAxisId's. Just set them both to the same, you can also remove the unused yAxes object from the options

Is there a way funnel chart will redraw like pie chart does, when a segment is removed?
Similar to this question redraw pie chart in highchart
http://jsfiddle.net/2Me2z/
$(function () {
var chart = new Highcharts.Chart({
chart: {
renderTo: 'container',
type: 'pie'
},
plotOptions: {
pie: {
showInLegend: true
}
},
legend: {
enabled: true
},
series: [{
data: [20, 30, 30, 20]
}]
});
// button handler
$('#button').click(function() {
var series = chart.series[0];
if (series.data.length) {
chart.series[0].data[0].remove();
}
});
});
So click on any slice in legend will cause the chart to redraw and the remaining slices will take up 100%
Wonder if the same thing can be done for a funnel chart
http://jsfiddle.net/YUL5c/2/
$(function () {
var chart;
$(document).ready(function () {
// Build the chart
$('#container').highcharts({
chart: {
type: 'funnel',
plotBackgroundColor: null,
plotBorderWidth: null,
plotShadow: false
},
title: {
text: 'Browser market shares at a specific website, 2010'
},
tooltip: {
pointFormat: '{series.name}: <b>{point.percentage:.1f}%</b>'
},
plotOptions: {
series: {
allowPointSelect: true,
cursor: 'pointer',
dataLabels: {
enabled: false
},
showInLegend: true
}
},
series: [{
name: 'Browser share',
data: [
['Firefox', 45.0],
['IE', 26.8],
{
name: 'Chrome',
y: 12.8,
sliced: true,
selected: true
},
['Safari', 8.5],
['Opera', 6.2],
['Others', 0.01]
]
}]
});
});
});
Currently the segment just disaapear. But the chart does not redraw
Unfortunately this animation is not supported, but I advice to post your request on the uservoice website
point.visible flag is ignored in funnel code.
If adding the check back to the drawing logic things just work magically. Even for the animation.
Not sure if it is a bug or ignored by intention
