Highcharts - Pie Chart change slice colors dynamically - javascript

The chart calls in JSON file that hold a string(color) and integer(count). I want to change the color of the each slice in a pie chart according to what the JSON file holds. So if the JSON file is [["Green",1],["Red",44],["Yellow",30]] I would like the the "Green" slice to have the color of green...etc. I've tried:
plotOptions: {
pie: {
//colors: ['#739600', '#bb0826', '#fcc60A'],
formatter: function () {
if ('Green' === this.value) {
return '<span style="fill: #739600;">' + this.value + '</span>';
}
else if ('Red' === this.value) {
return '<span style="fill: #bb0826;">' + this.value + '</span>';
}
else if ('Yellow' === this.value) {
return '<span style="fill: #fcc60A;">' + this.value + '</span>';
}
}, ...
It's not working how I expected. http://jsfiddle.net/LazerickL/bvaxmcLr/4/
Any help would be appreciated.
UPDATE
I had to restructure my JavaScript to call $.getJSON function. So, how would I proceed to implement the color slices for my latest code below? Thanks for any help!
$(document).ready(function() {
var options = {
chart: {
renderTo: 'containter',
defaultSeriesType: 'pie',
options3d: {
enabled: true,
alpha: 45
}
},
title: {
text: null
},
credits: {
enabled: false
},
tooltip: {
pointFormat:
'{series.name}: <b>{point.y}</b>'
},
plotOptions: {
pie: {
//colors: ['#739600', '#bb0826', '#fcc60A'],
allowPointSelect: true,
cursor: 'pointer',
depth: 30,
showInLegend: true,
dataLabels: {
enabled: true,
color: '#000000',
connectorColor: '#000000',
formatter: function () {
return '<b>' + this.point.name + '</b>: ' + this.point.y;
}
}
}
},
series: [{
type: 'pie',
name: 'Amount',
data: []
}]
}
$.getJSON("js/test.json", function (json) {
options.series[0].data = json;
var chart = new Highcharts.Chart(options);
});
});

To set your colors on your pies you'll need to update how you're pushing things into the data array to include the color of your pie. I accomplish this by adding a field to your data array but you could use an if statement like you had in the function if you prefer.
Here is an updated fiddle: http://jsfiddle.net/bvaxmcLr/8/
Also, your placement of the formatter function is invalid. That formatter javascript only applies to data labels as far as I know.
The important change from your script is removing the formatter function and updating to this to push the color value onto each data point:
var data={'d':[
{'Status_Color':'Green', 'Corrective_Action_ID':3},
{'Status_Color':'Red', 'Corrective_Action_ID':5},
{'Status_Color':'Yellow', 'Corrective_Action_ID':10},
]};
$.each(data.d, function (key, value) {
var colorVal = '';
if(value.Status_Color=='Green'){
colorVal = '#739600';
}
if(value.Status_Color=='Red'){
colorVal = '#bb0826';
}
if(value.Status_Color=='Yellow'){
colorVal = '#fcc60A';
}
var temp = {name:value.Status_Color, color:colorVal, y:value.Corrective_Action_ID};
options.series[0].data.push(temp);
})
Here is the whole script:
$(function () {
$(document).ready(function () {
var options = {
chart: {
renderTo: 'container',
type: 'pie',
options3d: {
enabled: true,
alpha: 45
}
},
title: {
text: null
},
subtitle: {
text: null
},
credits: {
enabled: false
},
tooltip: {
pointFormat: '{series.name}: <b>{point.y:.1f}</b>'
},
plotOptions: {
pie: {
depth: 45,
allowPointSelect: true,
cursor: 'pointer',
dataLabels: {
enabled: false
},
showInLegend: true
}
},
series: [{
type: 'pie',
name: 'Amount',
data: []
}]
}
var data={'d':[
{'Status_Color':'Green', 'Corrective_Action_ID':3},
{'Status_Color':'Red', 'Corrective_Action_ID':5},
{'Status_Color':'Yellow', 'Corrective_Action_ID':10},
]};
$.each(data.d, function (key, value) {
var colorVal = '';
if(value.Status_Color=='Green'){
colorVal = '#739600';
}
if(value.Status_Color=='Red'){
colorVal = '#bb0826';
}
if(value.Status_Color=='Yellow'){
colorVal = '#fcc60A';
}
var temp = {name:value.Status_Color, color:colorVal, y:value.Corrective_Action_ID};
options.series[0].data.push(temp);
})
chart = new Highcharts.Chart(options);
});
});

how to show mutipal dynamic highcharts based on json data

I want to use json data to construct mutipal pie charts. And put the pie chart inside class container, so for example:
data.data[0].usedPercentage=0,
data.data[1].usedPercentage=20,
data.data[2].usedPercentage=0,
the output pie chart should display like 0%, 20%, 0% ,
but now they display the same all in 0%, could anybody give some clues about that? Thanks a lot
$.ajax({
type: "GET",
url: 'http://XXX.XXX.XXX.XX',
dataType:'json',
contentType:"application/json",
success:function(data){
console.log(data);
var used = new Array();
for (var i = 0; i < data.data.length; i++) {
used[i]=data.data[i].usedPercentage;
pieIndex(used[i]);
projectList +="<div class='container'>pie</div>"
function pieIndex(used){
$(function () {
// Using classes to select multiple containers
var $containers = $(".container");
// You just set the configuration object once
var chartConfig = {
chart: {
plotBackgroundColor: null,
plotBorderWidth: null,
plotShadow: false,
type: 'pie'
},
title: {
text: ''
},
tooltip: {
pointFormat: '{series.name}: <b>{point.percentage:.1f}%</b>'
},
plotOptions: {
pie: {
allowPointSelect: true,
cursor: 'pointer',
dataLabels: {
enabled: false
},
showInLegend: true
}
},
series: [{
name: 'precentage',
colorByPoint: true,
data: [{
name: 'Unused',
y: 100-Number(used),
color: '#eeeeee',
sliced: true,
selected: true
}, {
name: 'Used',
y: Number(used),
color: '#f34s12',
selected: true
}]
}]
};
$containers.each(function() {
$(this).highcharts(chartConfig);
});
});
}
},
error:function(){
alert("connection error");
}
});
});
Each chart need a unique id on the container. Looks like you are overwriting those containers with the last chart. Try using a different id on each container div. For example:
projectList +="<div id='pie-chart-container-" + i + "' class='container'>pie</div>"

How to add data tables to dynamically generated highcharts

I want to add data tables to Charts.
I tried the implementation shown here: http://jsfiddle.net/highcharts/z9zXM/
but it didnt work for me.
I suspect its because how I instantiate highcharts.
in the example above the chart is generated by instantiating the Highcharts object.
my code:
// data from an ajax call
$.each(data, function(indicator, questions) {
indicator_type = "";
$.each(questions, function(question, value) {
dataChartType = "column";
series = [];
categories = [];
category_totals = {};
if(value.programs == null) {
return true;
}
$.each(value.programs, function(program, body) {
total = 0;
values = [];
$.each(body, function(j, k) {
if (categories.indexOf(j) == -1) {
categories.push(j);
category_totals[j] = 0;
}
if(k != 0) {
values.push(k);
} else {
values.push(null);
}
category_totals[j] += parseInt(k, 10);
total += k;
});
series.push({
data: values,
total: total,
name: program //question
});
}); // eo each program
var chartDiv = document.createElement('div');
chartDiv.className = "chart";
$('.charts_wrap').append(chartDiv);
$(chartDiv).highcharts({
events: {
load: Highcharts.drawTable
},
chart: {
type: dataChartType
},
xAxis: {
categories: categories
},
legend: {
layout: 'vertical',
backgroundColor: '#FFFFFF',
align: 'right',
verticalAlign: 'top',
y: 60,
x: -60
},
tooltip: {
formatter: function () {
return '<strong>' + this.series.name + '</strong><br/>' + this.x + ': ' + this.y;
}
},
plotOptions: {
line: {
connectNulls: true
},
column: {
stacking: 'normal',
dataLabels: {
enabled: false,
color: (Highcharts.theme && Highcharts.theme.dataLabelsColor) || 'white',
style: {
textShadow: '0 0 3px w'
}
}
}
},
series: series,
title:{ text: indicator },
subtitle:{ text: question }
});
}); // EO each question
}); // eo each indicator
When instantiating highcharts like this:
$("#container").highcharts({ ...
The events option needs to be included inside the charts option:
$("#container").highcharts({
chart: {
type: 'column',
events: {
load: Highcharts.drawTable
},
},
...

incorrect callback function string

I am using this code belong to plot currency change values but there is a problem while plotting chart.
$(document).ready(function () {

}
this.chart1.yAxisMax = (function(array){

when i run this code, i get an error message in console "Not acceptable : http://finance.yahoo.com/webservice/v1/symbols/allcurrencies/quote?format=json&view=basic&callback=jQuery18203581249208157574_1452451202663&_=1452451202773".
though the api i have used is correct but the string that callback function returns seems to be incorrect.

Highcharts bar chart wont animate

Not sure why because I have done it in the past, but I have a Highcharts bar chart and it won't animate. This is the declaration of the chart,
function initializeData() {
$http.get(url).success(function(ret) {
$scope.jsondata = ret;
var newdata = [];
for (x = 0; x < 5; x++) {
newdata.push({
name: setName($scope.jsondata[x].name),
y: $scope.jsondata[x].data[0],
color: getColor($scope.jsondata[x].data[0])
});
}
$scope.chart.series[0].setData(newdata);
});
mainInterval = $interval(updateData, 5000);
}
function updateData() {
$http.get(url).success(function(ret) {
$scope.jsondata = ret;
console.debug("here");
for (x = 0; x < 5; x++) {
$scope.chart.series[0].data[x].update({
y: $scope.jsondata[x].data[0],
color: getColor($scope.jsondata[x].data[0])
});
}
});
}
$scope.chart = new Highcharts.Chart({
chart: {
renderTo: 'container',
type: 'bar',
animation: true,
events: {
load: initializeData
}
},
title: {
text: ''
},
xAxis: {
type: 'category',
labels: {
style: {
fontSize: '11px'
}
}
},
yAxis: {
min: 0,
max: 100,
title: {
text: 'Total Score',
align: 'high'
}
},
legend: {
enabled: false
},
tooltip: {
pointFormat: 'Total Score <b>{point.y:.3f}</b>'
},
series: [{
name: 'Active Users',
data: [],
dataLabels: {
enabled: true,
rotation: 30,
style: {
fontSize: '10px',
fontFamily: 'Verdana, sans-serif'
},
format: '{point.y:.3f}', // one decimal
}
}]
});
And as you can see I have animate : true, so I am not sure what is the problem here. I have this older plunker where all of the data is in separate series, but it animates fine. But this is the plunker I am working on and having trouble with. They are like identical basically. In the newer one I broke out the initialization of data into its own method, but that is the only real main difference.
Some edits:
So as I was saying, I have done things this way with an areaspline chart (I know it was said they work a bit different but they are set up identically).
function initializeData() {
$interval.cancel(mainInterval);
$scope.previousPackets = '';
$http.get("https://api.myjson.com/bins/nodx").success(function(returnedData) {
var newdata = [];
var x = (new Date()).getTime();
for (var step = 9; step >= 0; step--) {
newdata.push([x - 1000 * step, 0]);
}
$scope.chart.series[0].setData(newdata);
});
mainInterval = $interval(updateData, 2000);
}
function updateData() {
$http.get(url + acronym + '/latest').success(function(returnedData) {
var x = (new Date()).getTime();
if ($scope.previousPackets != returnedData[0].numPackets) {
$scope.chart.series[0].addPoint([x, returnedData[0].numPackets], true, true);
$scope.previousPackets = returnedData[0].numPackets;
} else {
$scope.chart.series[0].addPoint([x, 0], true, true);
}
});
}
$scope.chart = new Highcharts.Chart({
chart: {
renderTo: 'container',
type: 'areaspline',
animation: Highcharts.svg, // don't animate in old IE
marginRight: 10,
events: {
load: initializeData
}
},
title: {
text: ''
},
xAxis: {
type: 'datetime',
tickPixelInterval: 150
},
yAxis: {
title: {
text: 'Packets'
},
plotLines: [{
value: 0,
width: 1,
color: '#d9534f'
}]
},
tooltip: {
formatter: function() {
return Highcharts.numberFormat(this.y) + ' packets<b> | </b>' + Highcharts.dateFormat('%H:%M:%S', this.x);
}
},
legend: {
enabled: false
},
exporting: {
enabled: false
},
series: [{
name: 'Packets',
data: []
}]
});
I also updated the first chunk of code with the initializeData() method and updateData() method which are seemingly identical in both different charts.
It looks like it plays an important role if you provide your data at chart initialization or after. For simplicity I refactored your code a little
function initializeChart(initialData, onload) {
$scope.chart = new Highcharts.Chart({
chart: {
renderTo: 'container',
type: 'bar',
animation: true,
events: {
load: onload
}
....
series: [{
name: 'Active Users',
data: initialData,
dataLabels: {
enabled: true,
format: '{point.y:.3f}', // one decimal
}
}]
});
}
function getData(callback) {
$http.get(url).success(function(ret) {
$scope.jsondata = ret;
var newdata = [];
for (x = 0; x < 5; x++) {
newdata.push([setName(ret[x].name), ret[x].data]);
}
callback(newdata);
});
}
As a result your two planks are in essense reduced to two methods below. The first initializes chart with preloaded data and the second updates data in existing chart.
function readDataFirst() {
getData(function(newdata) {
initializeChart(newdata);
});
}
function initializeChartFirst() {
initializeChart([], function() {
getData(function(newdata) {
$scope.chart.series[0].setData(newdata);
})
});
}
The first one animates fine while the second does not. It looks like highcharts skips animation if dataset is not initial and is treated incompatible.
However if you really want to have animation in your current plant (chart first workflow) you can achieve that by initializing first serie with zeros and then with the real data. This case it will be treated as update
function forceAnimationByDoubleInitialization() {
getData(function(newdata) {
initializeChart([]);
var zerodata = newdata.map(function(item) {
return [item[0], 0]
});
$scope.chart.series[0].setData(zerodata);
$scope.chart.series[0].setData(newdata);
});

HighStock graphic data array format

im using HighStock multiple series: http://www.highcharts.com/stock/demo/compare
The problem is that my application gives me this data format:
[data1],
[data2],
and HighStock is expecting this:
[
[data1],
[data2],
]
My JS for loading data is:
$(function () {
var seriesOptions = [],
seriesCounter = 0,
names = ['MSFT', 'AAPL', 'GOOG'],
// create the chart when all data is loaded
createChart = function () {
$('#graph1').highcharts('StockChart', {
legend: {
enabled: true,
align: 'center',
verticalAlign: 'bottom',
},
credits:{
enabled: false
},
title: {
text: 'Bitcoin Exchanges'
},
rangeSelector: {
selected: 4
},
yAxis: {
labels: {
formatter: function () {
return (this.value > 0 ? ' + ' : '') + this.value + '%';
}
},
plotLines: [{
value: 0,
width: 2,
color: 'silver'
}]
},
plotOptions: {
series: {
compare: 'percent'
}
},
tooltip: {
pointFormat: '<span style="color:{series.color}">{series.name}</span>: <b>{point.y}</b> ({point.change}%)<br/>',
valueDecimals: 2
},
series: seriesOptions
});
};
$.each(names, function (i, name) {
$.getJSON('http://www.highcharts.com/samples/data/jsonp.php?filename=' + name.toLowerCase() + '-c.json&callback=?', function (data) {
seriesOptions[i] = {
name: name,
data: data
};
seriesCounter += 1;
if (seriesCounter === names.length) {
createChart();
}
});
});
});
How can I push that data to an parent array so the library can consume it?
Thanks in advance.
