My Script is Here :
<script type="text/javascript">
var data = <?php echo json_encode($json_data) ?>
data.forEach(function(el) {
el.name = el.label;
el.y = Number(el.value);
});
Highcharts.chart('userpie', {
chart: {
plotBackgroundColor: null,
plotBorderWidth: null,
plotShadow: false,
type: 'pie'
},
title: {
text: undefined
},
credits: {
enabled: false
},
exporting: { enabled: false } ,
tooltip: {
pointFormat: '{series.name}: <b>{point.percentage:.1f}%</b>'
},
plotOptions: {
pie: {
allowPointSelect: true,
cursor: 'pointer',
showInLegend: true,
dataLabels: {
enabled: true,
format: '<b>{point.name}</b>: {point.percentage:.1f} %',
style: {
color: (Highcharts.theme &&
Highcharts.theme.contrastTextColor) || 'black'
}
}
}
},
series: [{
name: 'Users',
colorByPoint: true,
data: data
}]
});
</script>
Am I missing Something ?. Please Help. Thanks in Advance

You can change the opacity property in the inactive state:
plotOptions: {
pie: {
states: {
inactive: {
opacity: 1
}
},
...
}
}

how to draw hour and minute value (hh:mm) pie chart using highcharts,javascript

how to draw hh:mm pie chart using highcharts for bellow table

You could try this approach, we get the total amount of time, then create a highcharts chart from the individual points:
const data = [
{
name: 'Line Clear - Line maintenance',
value: '06:29',
color: '#eef441'
},
{
name: 'Incoming Supply Failure (ICF)',
value: '14:44',
color: '#f44242'
},
{
name: '33 KV Line Breakdown',
value: '02:13',
color: '#41f48b'
},
{
name: 'Line Clear - SS maintenance',
value: '00:10',
color: '#4176f4'
},
{
name: 'Momentary Interruptions',
value: '01:11',
color: '#e541f4'
}
];
var totalTimeSeconds = data.reduce((sum,row) => {
return sum + 1.0*moment.duration(row.value).asSeconds();
}, 0.0);
var dataSeries = data.map((row) => {
return {
name: row.name + " (" + row.value +")",
y: moment.duration(row.value).asSeconds() / totalTimeSeconds,
color: row.color
};
});
Highcharts.chart('container', {
chart: {
plotBackgroundColor: null,
plotBorderWidth: null,
plotShadow: false,
type: 'pie'
},
title: {
text: 'Reason Type'
},
tooltip: {
pointFormat: '{series.name}: <b>{point.percentage:.1f}%</b>'
},
plotOptions: {
pie: {
allowPointSelect: true,
cursor: 'pointer',
dataLabels: {
enabled: true,
format: '<b>{point.name}</b>: {point.percentage:.1f} %',
style: {
color: (Highcharts.theme && Highcharts.theme.contrastTextColor) || 'black'
}
}
}
},
series: [{
name: 'Reason',
colorByPoint: true,
data: dataSeries
}]
});
Here's a JSFiddle that demonstrates this: Reason-Chart

Highcharts. Dynamic labels inside donut chart on mouseOver

so this is what I'm trying to acomplish:
Example
What I need is:
Label inside donut chart changing on mouse over
Color depending on data
Styling label to look like the picture
I actually managed to do the mouse over but I can't change the color according to data and place it in the middle
Here is a fiddle: https://jsfiddle.net/9cjxb97a/1/
Here is the code I wrote so far:
Highcharts.chart('container', {
chart: {
plotBackgroundColor: null,
plotBorderWidth: null,
plotShadow: false,
type: 'pie'
},
title: {
text: ''
},
exporting: {
enabled: false
},
tooltip: {
enabled: false
},
colors: ['red', 'blue', 'green'],
plotOptions: {
pie: {
allowPointSelect: true,
cursor: 'pointer',
dataLabels: {
enabled: false,
format: '<b>{point.name}</b>: {point.percentage:.1f} %',
style: {
color: (Highcharts.theme && Highcharts.theme.contrastTextColor) || 'black'
}
}
},
series: {
point: {
events: {
mouseOver: function() {
var chart = this.series.chart;
if (!chart.lbl) {
chart.lbl = chart.renderer.label('')
.attr({
padding: 10,
})
.css({
color: 'red',
})
.add();
}
chart.lbl
.show()
.attr({
text: this.y + '%'
});
}
}
},
},
},
series: [{

colorByPoint: true,
data: [{

Here's your code to display value in between circle.
Highcharts.chart('container', {
chart: {
plotBackgroundColor: null,
plotBorderWidth: null,
plotShadow: false,
type: 'pie'
},
title: {
text: ''
},
exporting:{
enabled:false
},
tooltip: {
enabled:false
},
colors:['red', 'blue', 'green'],
plotOptions: {
pie: {
allowPointSelect: true,
cursor: 'pointer',
dataLabels: {
enabled: false,
format: '<b>{point.name}</b>: {point.percentage:.1f} %',
style: {
color: (Highcharts.theme && Highcharts.theme.contrastTextColor) || 'black'
}
}
},
series: {
point: {
events: {
mouseOver: function () {
var chart = this.series.chart;
if (!chart.lbl) {
chart.lbl = chart.renderer.label('')
.attr({
padding: 10,
})
.css({
color: 'red',
})
.add();
}
chart.lbl
.show()
.attr({
text: this.y + '%'
});
}
}
},
},
},
tooltip: {
borderWidth: 0,
backgroundColor: 'none',
headerFormat: '',
shadow: false,
style: {
fontSize: '16px'
},
pointFormat: '<span style="font-size:40px;color:black; font-weight: bold">{point.y}%</span><br><span>50 Kg</span>{point.custom.customParam}',
positioner: function (labelWidth) {
return {
x: (this.chart.chartWidth - labelWidth) / 2,
y: this.chart.plotHeight/2
};
}
},

How can I place chart directly above the legend? (highcharts)

Here is what I achieved so far
http://jsfiddle.net/9r6Lr5gr/3/

},
exporting: {
enabled: false

enabled: false
},

lineWidth: 0,

}
},
yAxis: {
gridLineWidth: 0,
title: {

},
stackLabels: {
enabled: true,
style: {
fontWeight: 'bold',
color: 'gray'
},
formatter: function(){
return 'Total: ' + this.total;
}
},
labels: {
enabled: false
}
},
legend: {
reversed: true,
align: 'left'
},
plotOptions: {
series: {
stacking: 'normal',
pointWidth: 30,
dataLabels: {
enabled: true,
color: 'white',
style: {
fontWeight: 'none',
fontSize: 15
}
}
}
},
series: [{
name: 'Outstanding (due > 7 days)',
data: [41]
}, {
name: 'Outstanding (due < 7 days)',
data: [32]
}, {
name: 'Overdue',
data: [15]
}]
});
I want to place the bar chart directly above the legend. Also, is it possible the little horizontal line just before the bar chart. Thanks.

Highcharts - How to change display data and remove mouseover?

I have a Highcharts pie chart on my page, working fine.
What I would like to do is remove the values displayed on mouseover of the pie and instead display the values statically with dataLabels(?).
I am not that good at JS and have no idea where to start.
See image below for explanation.
$(function() {
$('#total').highcharts({
credits: {
enabled: false
},
data: {
table: document.getElementById('datatable_total'),
switchRowsAndColumns: true,
endRow: 1
},
chart: {
type: 'pie'
},
title: {
text: ''
},
yAxis: {
allowDecimals: false,
title: {
text: 'Units'
}
},
tooltip: {
formatter: function() {
return '<b>' + this.series.name + '</b><br/>' +
this.point.y + ' ' + this.point.name.toLowerCase();
}
},
navigation: {
buttonOptions: {
verticalAlign: 'bottom',
y: -20
}
}
});
});

$(function () {
Highcharts.chart('container', {
chart: {
plotBackgroundColor: null,
plotBorderWidth: null,
plotShadow: false,
type: 'pie'
},
title: {
text: ''
},
tooltip: {
pointFormat: '{series.name}: {point.y}'
},
plotOptions: {
pie: {
allowPointSelect: true,
cursor: 'pointer',
dataLabels: {
enabled: true,
format: '<b>{point.name}</b> <br>{point.y}</br>',
style: {
color: (Highcharts.theme && Highcharts.theme.contrastTextColor) || 'black'
}
}
}
},
series: [{
colorByPoint: true,
data: [{
name: 'Europe',
y: 50
}, {
name: 'Africa',
y: 25
}, {
name: 'Australia',
y: 18
}, {
name: 'US',
y: 7
}]
}]
});
