Here is a jsFiddle for an issue i have been trying to solve:
http://jsfiddle.net/kSSYg/
When the donut chart loads, the slices are not visible, but the legends are. When you hover over, they appear.
Has anyone else encountered this?
code
$(function () {
var chart;
$(document).ready(function() {
var colors = Highcharts.getOptions().colors,
categories = ['Security', 'Interfaces', 'SNMP', 'Management', 'General'],
name = 'Rule Categories',
data = [{"y":23.53,"drilldown":{"name":"Security","categories":["Pass","Fail"],"data":[11.77,11.77]}},{"y":23.53,"drilldown":{"name":"Interfaces","categories":["Pass","Fail"],"data":[23.53,0]}},{"y":23.53,"drilldown":{"name":"SNMP","categories":["Pass","Fail"],"data":[11.77,11.77]}},{"y":5.88,"drilldown":{"name":"Management","categories":["Pass","Fail"],"data":[5.88,0]}},{"y":23.53,"drilldown":{"name":"General","categories":["Pass","Fail"],"data":[23.53,0]}}];
// Build the data arrays
var browserData = [];
var versionsData = [];
for (var i = 0; i < data.length; i++) {
// add browser data
browserData.push({
name: categories[i],
y: data[i].y,
color: data[i].color
});
// add version data
for (var j = 0; j < data[i].drilldown.data.length; j++) {
var brightness = 0.2 - (j / data[i].drilldown.data.length) / 5 ;
versionsData.push({
name: data[i].drilldown.categories[j],
y: data[i].drilldown.data[j],
color: Highcharts.Color(data[i].color).brighten(brightness).get()
});
}
}
// Create the chart
chart = new Highcharts.Chart({
chart: {
renderTo: 'container',
type: 'pie'
},
title: {
text: 'Browser market share, April, 2011'
},
yAxis: {
title: {
text: 'Total percent market share'
}
},
plotOptions: {
pie: {
shadow: false

dataLabels: {
formatter: function() {
return this.y > 5 ? this.point.name : null;
},

}
}, {
name: 'Versions',
data: versionsData,

}
}
}]
});
});
});
Do you have to define your own colors? If you remove the two lines which are setting the colors, it works. See http://jsfiddle.net/kSSYg/2/
remove:
color: data[i].color
and
color: Highcharts.Color(data[i].color).brighten(brightness).get()
The reason these lines are not working is because your data array objects do not define the attribute "color"

SO What I am trying to do is that I am trying to fetch data from CSV File, and from other CSV file I am trying to Highlight a particular area from the Chart.
For Eg.:
This is the Chart I am getting .
By adding the Following Code.
$.get('abc.csv', function(data) {
var lines = []
lines = data.split('\n');
console.log(lines);
var ecgData=[];
$.each(lines, function(lineNo, lineContent){
if(lineNo >= 0)
{
ecgData[lineNo-0] = parseFloat(lineContent.substring(lineContent.lastIndexOf(",")+1) );
//gibber=500;
//m=m+500;
}//console.log('PPG Data', ppgData[ppgNo-0])
});
featurex = [5,10,14,34,56,78,90,95] ;
featurey = [0,0,1,0,0,3,0,2];
zip = (xs, ys) => xs.reduce((acc, x, i) => (acc.push([x, ys[i]]), acc), []);
//console.log(ecg);
console.log(ecgData);
Highcharts.chart('ecg', {
chart: {
type: 'line',
zoomType: 'xy',
panning: true,
panKey: 'shift'
},
credits: {
enabled: false
},
title: {
text: 'ECG Data'
},
subtitle: {
text: ''
},
xAxis: {
crosshair: false
},
yAxis: {
title: {
text: 'ECG Peaks'
}
},
tooltip: {
enabled: false
},
plotOptions: {
column: {
pointPadding: 0.2,
borderWidth: 0
}
},
series: [{
name: '',
lineWidth: 1,
data: ecgData,
animation: {
duration: 14000
}
},
{ type: 'column',
name: 'Features',
data: zip(featurex, featurey),
animation: {
duration: 14000
}
}
]
});
});
My Chart :
Now as you can see from the Chart. I am getting the features data as bars in the chart.
featurex = [5,10,14,34,56,78,90,95] ;
featurey = [0,0,1,0,0,3,0,2];
but that is not what I want what I want is that where the features x value is 1, I want to highlight that area with a particular color, where it is 2, it should be filled with other color Like an example below:
Note: its just an example how the data should look don't math the data with the above image data.
I hope my question is clear.
In the load event you can check if a point meets your condition and add plotBands to your chart.
chart: {
events: {
load: function() {
var xAxis = this.xAxis[0],
points = this.series[0].points,
from,
to,
plotBands = [];
points.forEach(function(point, i) {
from = points[i - 1] ? points[i - 1].x : point.x;
to = points[i + 1] ? points[i + 1].x : point.x;
if (point.y === 1) {
plotBands.push({
color: 'blue',
from: from,
to: to
});
} else if (point.y === 2) {
plotBands.push({
color: 'green',
from: from,
to: to
});
}
});
xAxis.update({
plotBands: plotBands
});
}
}
}

I am Trying to Display The Total Users on the PieChart. But my "getting the Total Code" is not Working. It Displays Nothing.
Here is The Code that I am Using :
events: {
load: function(event) {
var total = 0;
for(var i=0, len=this.series[0].yData.length; i<len; i++){
total += this.series[0].yData[i];
}
var text = this.renderer.text(
'Total: ' + total,
this.plotLeft,
this.plotTop - 20
).attr({
zIndex: 5
}).add()
}
}
If I Can Show You My Full Code Here it is :
var data = <?php echo $data ; ?>
data.forEach(function(el) {
el.name = el.label;
el.y = Number(el.value);
});
Highcharts.chart('pieDiv', {
chart: {

I am Able to Get the Data on the Pie Chart . but the Total is not being Displayed. It was supposed to be appear on the top Left Corner of the Box
You've made a simple mistake in js for loop code using , instead of ;. Check the code and working demo with total data rendered properly.
Code:
chart: {
events: {
load: function() {
var total = 0,
len = this.series[0].yData.length,
text;
for (var i = 0; i < len; i++) {
total += this.series[0].yData[i];
}
text = this.renderer.text(
'Total: ' + total,
this.plotLeft,
this.plotTop - 20
).attr({
zIndex: 5
}).add();
}
}
}

I want to process data from a .csv file to:

I'm not sure what you are asking, but I'll take a shot at it...
First things first, this snippet of code is not sound. It'll not only skip NaNs but 0s as well (which is valid numeric data):
else if(parseFloat(csvData[rowIndex][colIndex]))
{
seriesItem.data.push(parseFloat(csvData[rowIndex][colIndex]));
}
Instead I'd do:
//first column data as categories,
if (colIndex == 0)
{
categories.push(csvData[rowIndex][0]);
}
else
{
var fVal = parseFloat(csvData[rowIndex][colIndex]);
if (!isNaN(fVal))
{
fVal = fVal / 10.0; //<-- here's the division!!
seriesItem.data.push(fVal);
}
}
As far as how to exclude outliers, the big question there is how do you want to exclude outliers? A simple min/max criteria? Then just check that fVal is within those limits before seriesItem.data.push...
I'm attempting to create a "ring chart" similar to the ones found here (scroll down to ring charts) with Highcharts using a donut chart. So, if I want to display a data value of 46% of something, it circles around counter-clockwise to 46% and stops.
I don't have a lot to go off of at this point, but here is a fiddle with what I have so far.
And code:
$(function () {
// Create the chart
$('#container').highcharts({
chart: {
type: 'pie'
},
title: {
text: 'Browser market share, April, 2011'
},
yAxis: {
title: {
text: 'Total percent market share'
}
},
plotOptions: {
pie: {
shadow: false,
center: ['50%', '50%']
}
},
tooltip: {
valueSuffix: '%'
},
series: [ {
name: 'Art Education',
data: [
['Covered by contributions',46]
],
size: '70%',
innerSize: '40%',
dataLabels: {
formatter: function() {
// display only if larger than 1
return this.y > 1 ? '<b>'+ this.series.name +':</b> '+ this.y +'%' : null;
}
}
}, {
name: 'Versions',
data: [1, 2],
size: '80%',
innerSize: '70%',
dataLabels: {
formatter: function() {
// display only if larger than 1
return this.y > 1 ? '<b>'+ this.point.name +':</b> '+ this.y +'%' : null;
}
}
}]
});
});

2017 Update:
Highcharts can now do Semi circle donut charts which is what I was looking for. Example.
Simple example using polar chart with some data interpolation: http://jsfiddle.net/ghvKY/
function interpolateData (min, max, step, index) {
var d = [];
// add points from start to one before last
for(var i = min; i < max; i += step){
d.push([i,index]);
}
//add end point
d.push([max, index]);
return d;
}
(function($){
$(function () {
$(document).ready(function() {
Highcharts.setOptions({
global: {
useUTC: false
}
});
var i=0;
var chart = new Highcharts.Chart({
chart: {
type: 'spline',
renderTo: 'container',
animation: Highcharts.svg, // don't animate in old IE
marginRight: 10,
events: {
load: function() {
// set up the updating of the chart each second
var series = this.series[0];
setInterval(function() {
var Name = new Array();
Name[0] = "Random data";
Name[1] = "Volvo";
var length=chart.series.length;
var flag=0;
var index=0;
var x = (new Date()).getTime(), // current time
y = Math.random();
for (var k=0;k<Name.length;k++) {
for(var j=0;j<chart.series.length;j++) {
if(chart.series[j].name==Name[k]) {
flag=1;
index=j;
x = (new Date()).getTime();
y = Math.random();
break;
}
}
if(flag==1) {
chart.series[index].addPoint([x, y], true, true);
flag=0;
} else {
chart.addSeries({name: '' + Name[k] + '', data: [] });
chart.series[length].addPoint([x, y+1], true);
length=length+1;
}
}
}, 1000);

I am able to add series and add point in charts but the series that I add after initialization, which is "volvo", is not drawing lines between its points. What might be the problem?
And is there any other way of comparing arrays and adding points without a for-loop? Because I can get millions of series at times and I don't want to be looping over arrays to check if it exists or not. So is there any efficient way of finding wheteher a list already exists, and if it does what is its index?
here is its fiddle: www.jsfiddle.net/2jYLz/
It is related with fact that you have enabled shifting in addPoint() when you add new serie. In other words, shifting remove first point and add new in the end of serie. So when you have one point it caused your scenario. So you need to disable shipfing, and when lenght of series.data achieve i.e 10 points, shifting should be enabled.
