Pie Chart Not Popping Up HighCharts

I am trying to make a pie chart that shows that rating of a python course. However every time I try to run it, the pie chart doesn't pop up, only the title. I am using HighCharts to create the pie chart and it is also supposed to be interactive. This is what I am using to create the pie chart. I also don't get any error message. Please help me.

I had the same problem.
I fixed it by removing (or commenting out) the 2 code lines below, which set the "plotBackgroundColor" and "plotBorderWidth" properties to null:
chart_def = """

//plotBackgroundColor: null, --> remove or comment out this line
//plotBorderWidth: null, --> remove or comment out this line

Highcharts: Add multiple colors to area line chart

I am trying to create a chart like this one:
:
I have already achieved all of the features except the multi colored line of the area chart. I want to show the different gradients of the chart in different colors, thus I need multiple colors on the line.
I have already tested zones like shown here and also common plugins like this. Both do not work. The zones are applied to the area which I do not want and the plugin can only color lines OR areas but not only lines in area charts.
My current Highcharts settings look like this:
{
title: {
text: null
},
xAxis: {
crosshair: true,
labels: {
format: '{value} km'
},
title: {
text: null
},
opposite: true,
startOnTick: true,
endOnTick: false,
min: 0
},
yAxis: {
startOnTick: true,
showFirstLabel: false,
endOnTick: false,
maxPadding: 0.35,
title: {
text: null
},
min: 100,
labels: {
format: '{value} m'
}
},
plotOptions: {
dataGrouping: {
enabled: false
},
showInNavigator: true,
stacking: 'normal',
series: {
dragDrop: {
draggableY: true
},
point: {
events: {
mouseOver: (e) => {
this.chartHover.emit({
distance: e.target.x * 1000
});
},
}
},
},
area: {
dragDrop: {
draggableY: true,
dragPrecisionY: 1
}
}
},
credits: {
enabled: false
},
legend: {
enabled: false
},
chart: {
update: true,
styledMode: true,
marginBottom: 0,
marginRight: 0
},
tooltip: {
headerFormat: '',
pointFormatter: function () {
let point = this;
if (!this.series) {
return;
}
return '<span class="tooltip-area-series-' + this.series.index + '">\u25CF</span> ' + point.series.name + ': <b>' + point.y + 'm</b><br/>';
},
shared: true
},
series: [],
};
Is there an built-in solution for this?
EDIT:
I used the proposed solution by ppotaczek:
series: [{
type: 'areaspline',
id: 'areaSeries',
data: data
}, {
type: 'spline',
linkedTo: 'areaSeries',
data: data,
zoneAxis: 'x',
zones: [{
color: 'red',
value: 2
}, {
color: 'green',
value: 4
}]
}]
This works pretty good, but has some performance pitfalls when you try to add approx. more than 150 zones on desktop browsers.
There is also a small rendering issue - small gaps between the zones.
Best,
Philipp

You can add an extra spline series with zones:
series: [{
type: 'areaspline',
id: 'areaSeries',
data: data
}, {
type: 'spline',
linkedTo: 'areaSeries',
data: data,
zoneAxis: 'x',
zones: [{
color: 'red',
value: 2
}, {
color: 'green',
value: 4
}]
}]

Highchart reloading upon call issue - javascript

Hi I'm trying to update my piechart LIVE without redrawing the piechart, any advice?
this is the function that is being called
var i = 0;
setInterval(function(){
piecharts(i, 1, 2, 3, 4, 5);
i++;
},5000);
function piecharts(sector0Data, sector1Data, sector2Data, sector3Data, sector4Data, sector5Data)
{
$('#container').highcharts({
chart: {
plotBackgroundColor: null,
plotBorderWidth: null,
plotShadow: false,
type: 'pie',
options3d: {
enabled: false,
alpha: 45,
beta: 0
}
},
title: {
text: 'Number of person in each sector'
},
tooltip: {
pointFormat: '{series.name}: <b>{point.y}</b>'
},
plotOptions: {
pie: {
allowPointSelect: true,
cursor: 'pointer',
depth: 35,
dataLabels: {
enabled: true,
format: '<b>{point.name}</b>: {point.y} ', //change percentage to y for decimal value
style: {
color: (Highcharts.theme && Highcharts.theme.contrastTextColor) || 'black'
}
}
}
},
series: [{
name: 'Avg number of person in this sector over the total of ',
colorByPoint: true,
data: [{
name: 'Sector0',
y: sector0Data
},{
name: 'Sector1',
y: sector1Data
},{
name: 'Sector2',
y: sector2Data
},{
name: 'Sector3',
y: sector3Data
},{
name: 'Sector4',
y: sector4Data
}, {
name: 'Sector5',
y: sector5Data
}]
}]
});
}
For every 5 second, my i will increase by 1 and my pie-chart will be drawn, this works fine but it kept redrawing my chart. any advice? thanks. also, i'm using v4.1.8 of highchart

You should use the update() method for this. Init your chart on the DOM ready event and just call a function in order to update data :
Demo
function updatePiechart(sector0Data, sector1Data, sector2Data, sector3Data, sector4Data, sector5Data)
{
var chart = $('#container').highcharts();
chart.series[0].update({
data: [{
name: 'Sector0',
y: sector0Data
},{
name: 'Sector1',
y: sector1Data
},{
name: 'Sector2',
y: sector2Data
},{
name: 'Sector3',
y: sector3Data
},{
name: 'Sector4',
y: sector4Data
}, {
name: 'Sector5',
y: sector5Data
}]
})
}

The reason for the re-render is that you create a new chart every five seconds instead of updating its data.
You need to call the update method for your y point on your chart series data:
chart.series[0].data[0].update(y);
Here is a simple example on how to update the data: Update pie data jsfiddle
Or have a look at the documentation for live data

How to pass a value into javascript array?

I am working on a pie chart for the admin dashboard to display some data about the users. I am getting the response from PHP file correctly and store it in result_from_PHP variable as you can see the code below. My problem is, I don't know how to pass this variable result_from_PHP to the series part in the code y: result_from_PHP. Can anyone help please ?
<script type="text/javascript">
$.getJSON("PHP_trader_behav.php", function(data){
$.each(data.result,function(){
var result_from_PHP = this['visitors_count'];
alert(result_from_PHP);
$(function () {
alert(result_from_PHP);
$('#container').highcharts({
chart: {
plotBackgroundColor: null,
plotBorderWidth: null,
plotShadow: false,
type: 'pie'
},
title: {
text: 'Browser market shares January, 2015 to May, 2015'
},
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: 'Brands',
colorByPoint: true,
data: [{
name: 'Microsoft Internet Explorer',
y: result_from_PHP
}, {
name: 'Chrome',
y: 5000,
sliced: true,
selected: true
}, {
name: 'Firefox',
y: 1000
}, {
name: 'Safari',
y:1000
}, {
name: 'Opera',
y: 4000
}, {
name: 'Proprietary or Undetectable',
y:3000
}]
}]
});
});
});
});
</script>

TRY THIS ONE
y: <?PHP echo result_from_PHP ?>
you have do whatever your wish with in the php tag

Build series array[in the form of json] using $.each , then use that variable into $('#container').highcharts({series:some-variable})

Highchart drilldown to simultaneous multiple series and y-axis

Hello I would like to use HighChart package and make JS figures with drilldown capability that
1. Show multiple series at drilled-down level at the same time.
2. Use multiple (say 2) y-axis to indicate the different units from these series at the drilled-down level.
Based on the starting point of the code:
$(function () {
// Create the chart
$('#container').highcharts({
chart: {
type: 'column'
},
title: {
text: 'Browser market shares. January, 2015 to May, 2015'
},
subtitle: {
text: 'Click the columns to view versions. Source: netmarketshare.com.'
},
xAxis: {
type: 'category'
},
yAxis: {
title: {
text: 'Total percent market share'
}
},
legend: {
enabled: false
},
plotOptions: {
series: {
borderWidth: 0,
dataLabels: {
enabled: true,
format: '{point.y:.1f}%'
}
}
},
tooltip: {
headerFormat: '<span style="font-size:11px">{series.name}</span><br>',
pointFormat: '<span style="color:{point.color}">{point.name}</span>: <b>{point.y:.2f}%</b> of total<br/>'
},
series: [{
name: 'Brands',
colorByPoint: true,
data: [{
name: 'Microsoft Internet Explorer',
y: 56.33,
drilldown: 'Microsoft Internet Explorer'
}, {
name: 'Chrome',
y: 24.03,
drilldown: 'Chrome'
}, {
name: 'Firefox',
y: 10.38,
drilldown: 'Firefox'
}, {
name: 'Safari',
y: 4.77,
drilldown: 'Safari'
}, {
name: 'Opera',
y: 0.91,
drilldown: 'Opera'
}, {
name: 'Proprietary or Undetectable',
y: 0.2,
drilldown: null
}]
}],
drilldown: {
series: [{
name: 'Microsoft Internet Explorer',
id: 'Microsoft Internet Explorer',
categories: ['v11','v8','v9','v10','v7'],
type: 'spline',
data: [
['v11',25],
['v8',17],
['v9',8],
['v10',5],
['v7',3]]
}, {
name: 'Chrome',
id: 'Chrome',
data: [
['v40.0',5],
['v41.0',4.32],
['v42.0',3.68]
]
}]
}
});
});
http://jsfiddle.net/h5xjp8h5/2/
with three js source code:
<script src="https://code.highcharts.com/highcharts.js"></script>
<script src="https://code.highcharts.com/modules/data.js"></script>
<script src="https://code.highcharts.com/modules/drilldown.js"></script>
But when i make the drilldown part code like the following:
drilldown: {
series: [{
name: 'Microsoft Internet Explorer',
id: 'Microsoft Internet Explorer',
type: 'spline',
data: [
['v11',25],
['v8',17],
['v9',8],
['v10',5],
['v7',3]]
}, {
name: 'Microsoft Internet Explorer Cost',
id: 'Microsoft Internet Explorer',
type: 'spline',
yAxis: 1,
data: [
['v11',50],
['v8',40],
['v9'60],
['v10',65],
['v7',73]]
}, {
name: 'Chrome',
id: 'Chrome',
data: [
['v40.0',5],
['v41.0',4.32],
['v42.0',3.68]
]
}]
}
With y-axis part:
yAxis: [{
title: {
text: 'Total percent market share'
}
},
{
title: {
text: 'cost'
},
opposite: true
}],
http://jsfiddle.net/h5xjp8h5/3/
It did not work.
Could someone please help me on this: 1) I want drill down on Microsoft Internet Explore into a view with two spline series, one with version usage and the other with version cost. 2) i want those two series in. 3) using two y-axis.
Thank you very much in advance.

You can use drilldown event callback function for add new series as your drilldown:
drilldown: function(e) {
var chart = this,
drilldowns = chart.userOptions.drilldown.series,
series = [];
e.preventDefault();
Highcharts.each(drilldowns, function(p, i) {
if (p.id.includes(e.point.name)) {
chart.addSingleSeriesAsDrilldown(e.point, p);
}
});
chart.applyDrilldown();
}
You can use addSingleSeriesAsDrilldown(), method similar to: http://api.highcharts.com/highcharts#Chart.addSeriesAsDrilldown
But you can add multiple series as drilldown with this method.
Here you can see an example how it can work:

Kind regards.
