I want to display a bar graph using highcharts.I am devoloping an app in play framework(play-java),in which I return a response from the java api which contains data in json format.It contains a field 'name' which contains data like 'Data','Gadgets','Others' etc.I want the x axis of the chart to take these values from json array which gets returned in response.
Here is the code for the response in .js
for(var i=0;i<response.data.result.length;i++)
{
$scope.total=$scope.total+parseInt(response.data.result[i].item_price);
}
var j=0;
console.log(response.data.result);
while(j<response.data.result.length)
{
$scope.jsonArray=[{
name:response.data.result[j].category_name,
y: (parseInt(response.data.result[j].item_price)/$scope.total)*100,
}]
$scope.renderChart();
}
The code for bar graph
$scope.renderChart = function()
{
Highcharts.chart('container', {
chart: {
type: 'column'
},
title: {
text: 'Your Expenses'
},
subtitle: {
text: 'Your total spent money is '+$scope.total+'.'
},
xAxis: {
type: 'category'
},
yAxis: {
title: {
text: 'Money spent in percentage'
}
},
legend: {
enabled: false
},
credits: {
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: 'Categories',
colorByPoint: true,
data:$scope.jsonArray
}]
});
}
I know that I can't use the while loop in the response code mentioned.That's where i am looking help for.The y axis should calculate the percentage value .I want to generate 'names' for x axis and percentage for y axis of the chart.Thanks in advance..
All we have to do is to just initialize the jsonArray as empty before doing the looping.Add a for loop so that it iterates through the array and assigns the values appropriately.
The changed code
$scope.jsonArray = [];
for(var i=0;i<response.data.result.length;i++)
{
$scope.jsonArray[i]={
name:response.data.result[i].category_name,
y: (parseInt(response.data.result[i].item_price)/$scope.total)*100,
}
$scope.renderChart();
console.log(response.data.result[i]);
}
console.log($scope.jsonArray);
})
Anyway thanks....

I've created an ajax request that returns data like this
Object
negative:3
neutral:3
positive:94
This is directly from console.log();
Im trying to create a pie chart using this data but when I try it doesn't draw the chart and nothing shows up except for the credits and no errors in the console either. But if I manually input data like this:
series: [{
name: 'Brands',
data: [
{ name: 'Positive', y: 94 },
{ name: 'Negative', y: 3 },
{ name: 'Neutral', y: 3 },
]
}]
it works no problem.
My code is:
function pieChart(data) {
// Make monochrome colors and set them as default for all pies
Highcharts.getOptions().plotOptions.pie.colors = (function () {
var colors = [],
base = Highcharts.getOptions().colors[0],
i;
for (i = 0; i < 10; i += 1) {
// Start out with a darkened base color (negative brighten), and end
// up with a much brighter color
colors.push(Highcharts.Color(base).brighten((i - 3) / 7).get());
}
return colors;
}());
// Build the chart
Highcharts.chart('pieChart', {
chart: {
plotBackgroundColor: null,
plotBorderWidth: null,
plotShadow: false,
type: 'pie'
},
title: {
text: 'Browser market shares at a specific website, 2014'
},
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',
data: data
}]
});
};
The response you've received from server using ajax request is an object.
All you need is to create a json array from the response you've received.
var object={'positive':94,'neutral':2,'negative':2};
var data=[];
for(i in object){
data.push({"name":i,"y":object[i]});
}
And set it to highchart series.
series: [{
name: 'Brands',
data: data
}]
I have this fiddle JSfiddle
Here is the reproduced code:
$(function () {
$('#container').highcharts({
chart: {
type: 'bar'
},
xAxis: {
categories: ['Heroku', 'Ruby','Lisp','Javascript','Python','PHP']
},
yAxis: {
categories: ['low','medium','high'],
title: {
text: 'expertise',
align: 'high'
},
labels: {
overflow: 'justify'
}
},
tooltip: {
valueSuffix: ' millions'
},
plotOptions: {
bar: {
dataLabels: {
enabled: true
}
}
},
series: [{
data: ['low','high','low','medium','medium']
}]
});
});
If you look at the fiddle the yAxis does not render and has a value of for every x category. I've been looking at the highcharts api, but I can't seem to get this right. The code makes sense to me but I'm obviously doing something wrong. Can someone point out why the YAxis is not displaying correctly?
As mentioned in my comment, you need to supply the numeric value of the category, not the category name.
In the case of categories, the numeric value is the array index.
Also, in your case, the way you are trying to plot the values, I would add an empty category at the beginning, otherwise your first category of low gets plotted as 0, which doesn't seem right.
So,
categories: ['low','medium','high']
Becomes
categories: ['','low','medium','high'],
And
data: ['low','high','low','medium','medium']
Becomes
data: [1,3,1,2,2]

Trick is to utilize the formatter function. You can use a similar formatter function on y-axis labels too if that's desired. Though it seems like you need it for data labels for this problem.
$(function() {
$('#container').highcharts({
chart: {
type: 'bar'
},
xAxis: {
categories: ['Heroku', 'Ruby', 'Lisp', 'Javascript', 'Python', 'PHP']
},
yAxis: {
title: {
text: 'expertise',
align: 'high'
},
labels: {
overflow: 'justify',
}
},
tooltip: {
valueSuffix: ' millions'
},
plotOptions: {
bar: {
dataLabels: {
enabled: true,
formatter: function() {
if (this.y == 0) {
return 'low'
} else if (this.y == 1) {
return 'medium'
} else {
console.log(this.y);
return 'high'
}
}
}
}
},
series: [{
data: [0, 2, 0, 1, 1]
}]
});
});
In my opinion, it is kinda unlikely for a line graph to have a y-axis category, since it speaks more of amount or value. In your case, "low, medium, and high" speaks of ranges, with which a certain value can be assigned to any of it.
Thus, Highcharts accepts series data in numeric form. But you can work around it by setting ['low', 'medium', 'high'] in the category attribute of yAxis, then setting series data as an array of number corresponding to the index of the category, i.e. [0,1,1,2,...] and tweaking the tooltip to display the category instead of the y value using formatter attribute.
Here is the code:
$(function() {
yCategories = ['low', 'medium', 'high'];
$('#container').highcharts({
title: {
text: 'Chart with category axes'
},
xAxis: {
categories: ['Heroku', 'Ruby','Lisp','Javascript','Python','PHP']
},
yAxis: {
categories: yCategories
},
tooltip: {
formatter: function() {
return this.point.category + ': ' + yCategories[this.y];
}
},
series: [{
data: [0, 1, 2, 2, 1]
}]
});
});
Here is a working example : JSFiddle
I am trying to do a drilldown chart like this one http://jsfiddle.net/gh/get/jquery/1.9.1/highslide-software/highcharts.com/tree/master/samples/highcharts/demo/column-drilldown/ and I am pretty close but I am trying loop my output of my items into an array and get the same format as the demo drilldown chart however it seems to only be getting the last set of items in my each loop. How can I keep the same format and pass them into my array? https://jsfiddle.net/pwbz0mxy/
chart_user_hours = {
chart: {
type: 'column',
renderTo: 'hours_chart_container'
},

}

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: [],
drilldown: {
series: []
}
};
data = '{"comparison":false,"title":"User Capacity Breakdown | January 2016 to July 2016","series":{"name":"User Hours Breakdown ","colorByPoint":true,"data":{"series":{"data":[{"name":"test","y":10,"drilldown":"test"},{"name":"test","y":154,"drilldown":"test"},{"name":"Large Move","y":29,"drilldown":"Large Move"},{"name":"Invoice 78554","y":20,"drilldown":"Invoice 78554"},{"name":"Small Move*","y":13,"drilldown":"Small Move*"}]}}},"drilldown":{"drilldown":{"series":[{"name":"test","id":"test","work_date":["2016-06-10"],"data":[10]},{"name":"test","id":"test","work_date":["2016-07-11","2016-07-10","2016-07-08","2016-07-06"],"data":[37,51,44,22]},{"name":"Large Move","id":"Large Move","work_date":["2016-07-04","2016-07-05","2016-07-08","2016-07-11"],"data":[9,8,7,5]},{"name":"Invoice 78554","id":"Invoice 78554","work_date":["2016-06-14","2016-06-24"],"data":[10,10]},{"name":"Small Move*","id":"Small Move*","work_date":["2016-06-30","2016-06-03"],"data":[3,9]}]}}}';
var obj = $.parseJSON(data);
chart_data = typeof obj.series.data.series != 'undefined' ? obj.series.data.series.data : '';
chart_user_hours['series'] = [{
name: obj.series.name,
data: chart_data
}];
$.each(obj.drilldown.drilldown.series, function( key, value ) {
chart_user_hours['drilldown']['series'] = [{
name: value.work_date,
id: value.id,
data: value.data
}];
});
var chart_hours = new Highcharts.Chart(chart_user_hours);
You are replacing the value of chart_user_hours['drilldown']['series'] each time in your loop. So actually it has to look like this:
Declaring the array – Before Loop
chart_user_hours['drilldown']['series'] = [];
Use push function of the array to add the value at the end of your array – In Loop
chart_user_hours['drilldown']['series'].push({
name: value.work_date,
id: value.id,
data: value.data
});
New to highcharts and as the title said I am trying to pull json from a webservice and place it into the chart (bar chart) but I am getting some weird behavior. after I pull the data down through $http.get() I try and set the series to that string of json like series: '$scope.jsondata'. It will fill some legends (more than expected) so it is getting the data. but the bars on the chart wont show.
On the other hand when I go to the url where I am getting the json and just copy and paste all of the json into the series field, it works perfectly.
I have a plunker here I have been working on that shows what I am talking about. You can just paste:
[
{
"name":"Kaia",
"data":[19]
},
{
"name":"Deborah",
"data":[86]
},
{
"name":"Phoebe",
"data":[77]
},
{
"name":"Rory",
"data":[17]
},
{
"name":"Savannah",
"data":[15]
}
]
...into the series field and everything works.
EDIT I havent yet, but I am planning to use $interval to update the data every x seconds. Something like :
$http.get(fullUrl).success(function(data2) {
$scope.records = [];
data2.forEach(function(r) {
$scope.records.push(r);
});
});
mainInterval = $interval(function() {
$http.get(fullUrl).success(function(data2) {
$scope.records = [];
data2.forEach(function(r) {
$scope.records.push(r);
});
});
}, 5000);
So like one of the answers suggested I put the chart creation in the callback of the $http.get() but I think that'd hinder the $interval
You can move the creation of the Chart into the callback of the get call to simplify things. http://plnkr.co/edit/utQG34xOQmtbOukTK71e?p=preview
Note I also updated series: '$scope.jsondata' to series: $scope.jsondata.
$http.get('https://api.myjson.com/bins/38qm9').success(function(ret) {
$scope.jsondata = ret;

I am trying to display values which I am getting dynamically. In the below code I am trying to store the values in array and I am trying to use the array values in "series: data".
Nothing is getting displayed in the graph.
I know this is very simple question but I did not get any satisfactory answer when I googled it. Please help
var x = window.location.search.replace( "?", "" );
x = x.substring(3);
var array = x.split(","); // I am storing my dynamic values in this array
$(function () {
//alert(array); ----- I am able to see the values here
$('#container').highcharts({
chart: {
type: 'bar'
},
title: {
text: 'Wireless Experience Meter'
},
subtitle: {
text: 'Sub - Time to Download'
},
xAxis: {
categories: ['Text'],
title: {
text: null
}
},
yAxis: {
min: 0,
title: {
text: 'Time (ms)',
align: 'high'
},

overflow: 'justify'
}

},
credits: {

},
series: [{
name: 'Attempt 1',
//data: [635, 203, 200]
data : [array[0]] // I need to pass the variables here to get it displayed
}, {
name: 'Attempt 2',
//data: [133, 408, 698]
data : [array[1]]
}, {
name: 'Attempt 3',
//data: [973, 914, 4054]
data : [array[2]]
}]
});
});
You don't tell us what the variable array equals but since its generated from x.split(","), it's elements are going to be strings and not the numeric values Highcharts needs.
So convert it with parseInt or parseFloat:
var numericData = [];
for (var i = 0; i < array.length; i++){
numericData.push(parseFloat(array[i]));
}
...
series: [{
name: 'Attempt 1',
data : numericData
},
...
[array[0]] is not an array, that looks like console output not javascript. But [[0]] or [0] technically would be. However, since a call to array (array(0)) generates an array then I think you want data: array(0).
Outside shot at data : [array(0)] if you didn't show the example data correctly. I've never used HighCharts so I don't know what it's expected but I still go with data : array(0)
