I have created Pie chart and it is working ok. In Pie Chart, Labels are showing % values and it is also fine. But now I just want to show % value in Legend item text also.
var ChartDesignCreated = c3.generate({
bindto: "#Chart1",
data: {
columns: [
['Football', 10)],
['Cricket', 10)],
],
type: 'pie'
}
});
Legend item text should be display like :
Football = 50%
Cricket = 50%
Is it possible?
Thanks.
There are no built-in way to do that.
However, you can just put percentage into data label texts before chart rendering:
var columns = [
['data1', 30],
['data2', 120]
];
var total = columns.reduce(function(sum, item) {
return sum + item[1]
}, 0);
columns = columns.map(function(item) {
return [
item[0] + ' = ' + d3.format('.1%')(item[1] / total),
item[1]
]
});
var chart = c3.generate({
data: {
columns: columns,
type : 'pie'
}
});

I've been trying for 3 days to get this chart to display the way I want it to. Everything was working 100% until I realized the grouped bar chart numbers were off.
Example: When the bottom bar value equals 10 and the top bar value equals 20, the top of the grouped bar read 30. This is the default behavior, but not how I want to represent my data. I want the top of the grouped bar to read whatever the highest number is, which lead me to this fiddle representing the data exactly how I wanted to.
After refactoring my logic, this is what I have so far. As you can see the timeseries line is broken up and the tooltip is not rendering the group of data being hovered over.
My questions:
1) How to get the tooltip to render all three data points (qty, price, searches)
2) How to solidify the timeseries line so it's not disconnected
Any help would be greatly appreciated so I can move on from this 3 day headache!
Below is most of my code - excluding the JSON array for brevity, which is obtainable at my jsfiddle link above. Thank you in advance for your time.
var chart = c3.generate({
bindto: '#chart',
data: {
x: 'x-axis',
type: 'bar',
json: json,
xFormat: '%Y-%m-%d',
keys: {
x: 'x-axis',
y: 'searches',
value: ['qty', 'searches', 'price']
},
types: {
searches: 'line'
},
groups: [
['qty', 'price']
],
axes: {
qty: 'y',
searches: 'y2'
},
names: {
qty: 'Quantity',
searches: 'Searches',
price: 'Price ($)'
},
colors: {
price: 'rgb(153, 153, 153)',
qty: 'rgb(217, 217, 217)',
searches: 'rgb(255, 127, 14)'
}
},
bar: {
width: {
ratio: 0.60
}
},
axis: {
x: {
type: 'timeseries',
label: { text: 'Timeline', position: 'outer-right' },
tick: {
format: '%Y-%m-%d'
}
},
y: {
type: 'bar',
label: {
text: 'Quantity / Price',
position: 'outer-middle'
}
},
y2: {
show: true,
label: {
text: 'Searches',
position: 'outer-middle'
}
}
},
tooltip: {
grouped: true,
contents: function(d, defaultTitleFormat, defaultValueFormat, color) {
var data = this.api.data.shown().map(function(series) {
var matchArr = series.values.filter(function(datum) {
return datum.value != undefined && datum.x === d[0].x;
});
if (matchArr.length > 0) {
matchArr[0].name = series.id;
return matchArr[0];
}
});
return this.getTooltipContent(data, defaultTitleFormat, defaultValueFormat, color);
}
}
});
1) If I got it right, you want tooltip to show all values, even if some of them are null.
Null values are hidden by default. You can replace them with zero (if it is suitable for your task) and thus make them visible.
Also, it seems to me that there is a shorter way to get grouped values:
var data = chart.internal.api.data().map(function(item) {
var row = item.values[d[0].index]; // get data for selected index
if (row.value === null) row.value = 0; // make null visible
return row;
});
2) I think you are talking about line.connectNull option:
line: {
connectNull: true
}
UPDATE
Looks like having duplicate keys breaks work of api.data() method.
You need to change json structure to make keys unique:
Before:
var json = [
{"x-axis":"2017-07-17","qty":100},
{"x-axis":"2017-07-17","price":111},
{"x-axis":"2017-07-17","searches":1},
{"x-axis":"2017-07-18","qty":200},
{"x-axis":"2017-07-18","price":222},
{"x-axis":"2017-07-18","searches":2}
];
After:
var json = [
{"x-axis":"2017-07-17","qty":100,"price":111,"searches":1},
{"x-axis":"2017-07-18","qty":200,"price":222,"searches":2}
];
See fiddle.
I am using Highcharts - Line - Ajax.
Let's say I have two series of data - 'Headcount 1' and 'Headcount 2'. I want to draw a line graph of 'Headcount', which is the sum of the 2 series. However, when someone hovers on one data point, I want to show the individual values in the callout. Is this possible? How can I do this?
e.g.
H1 = (1, 2, 3)
H2 = (5, 6, 7)
Ht = (6, 8, 10)
I will draw a line graph with Ht. If I hover on '6' on the chart, the callout should show the values of H1 = 1 and H2 = 5
You can set the visibility for series H1 and H2 to false,
series: [{
name: 'H1',
data: [1, 2, 3],
visible: false,
showInLegend: false
}, {
name: 'H2',
data: [5, 6, 7],
visible: false,
showInLegend: false
}, {
name: 'H',
data: [6, 8, 10]
}]
and edit tooltip formatter to display what you want
tooltip: {
formatter: function() {
var s = '<b>' + this.x + '</b>';
var chart = this.points[0].series.chart; //get the chart object
var categories = chart.xAxis[0].categories; //get the categories array
var index = 0;
while(this.x !== categories[index]){index++;} //compute the index of corr y value in each data arrays
$.each(chart.series, function(i, series) { //loop through series array
if (series.name !== 'H') {
s += '<br/>'+ series.name +': ' +
series.data[index].y +'m'; //use index to get the y value
}
});
return s;
},
shared: true
}
Have a look at jsfiddle.net/s190ebby/27/
Yes
Points can have custom property, taking care that the names do not shadow highcharts variable names.
var data = [{
y: 6,
h1Value: 1,
h2Value: 5
},{
y: 8,
h1Value: 2,
h2Value: 6
}];
Set your series to this data in your config object, by series: data
Customise the tooltip as:
tooltip: {
pointFormat: '<b>H Value</b>: {point.y}<br/>
<b>H1 Value</b>: {point.h1Value}<br/>
<b>H2 Value</b>: {point.h2Value}'
}
js is a very good library, but I have a problem:
in my graph each bar represents a value produced between two hours, but the tick text is below the bar and I want to get it between the bar !
my type of x-axis is "type: 'category'"
data = ['x', '01:00', '02:00', '03:00', '04:00', '05:00', '06:00']
Can someone help me?
Thank you in advance.

You could convert your x axis to a timeseries and have the values tagged to the actual midpoint of your hour ranges (12.30, 1.30...)
var chart = c3.generate({
data: {
x: 'x',
columns: [
['x',
new Date('2013-01-01T00:30'),
new Date('2013-01-01T01:30'),
new Date('2013-01-01T02:30'),
new Date('2013-01-01T03:30')],
['data1', 30, 200, 100, 400]
],
type: 'bar'
},
axis: {
x: {
type: 'timeseries',
tick: {
format: '%H:%M',
values: [
new Date('2013-01-01T00:00'),
new Date('2013-01-01T01:00'),
new Date('2013-01-01T02:00'),
new Date('2013-01-01T03:00'),
new Date('2013-01-01T04:00')
],
rotate: -90
},
height: 50
}
}
});

I tried to use this example in order to create a C3 chart. But its using all the data in the api. I am using angularjs.
my data looks like this
[
No:1
Name:'abc'
Id:3
Value:34
]
here is my code
d3.json("http://api.mydata", function(data) {
var convertedData = [];
data.forEach(function(item){
convertedData.push([item.Id, item.Value]);
});
var chart = c3.generate({
bindto : '#chartContainer',
data : {
columns : [convertedData]
},
keys: {
x: convertedData.ID,
value: convertedData.Value
}
});
});
thanks
The data field has to be populated with information about the axis as well. Here you have a functional example (sorry for the Spanish variables):
var chart = c3.generate({
bindto: "#chart-" + value.siglas,
data: {
x: 'x',
x_format: '%Y',
columns: [
['x', new Date('2011'), new Date('2012'), new Date('2013'), new Date('2014')],
['Primera matrícula', value.tasas_2011.tasas1, value.tasas_2012.tasas1, value.tasas_2013.tasas1, value.tasas_2014.tasas1],
['Segunda matrícula', value.tasas_2011.tasas2, value.tasas_2012.tasas2, value.tasas_2013.tasas2, value.tasas_2014.tasas2],
['Tercera matrícula', value.tasas_2011.tasas3, value.tasas_2012.tasas3, value.tasas_2013.tasas3, value.tasas_2014.tasas3],
['Cuarta matrícula', value.tasas_2011.tasas4, value.tasas_2012.tasas4, value.tasas_2013.tasas4, value.tasas_2014.tasas4],
['Media nacional' + averageErrorFlag, average['tasas_2011'].toFixed(2), average['tasas_2012'].toFixed(2), average['tasas_2013'].toFixed(2), average['tasas_2014'].toFixed(2)]
]
},
axis: {
x: {
type: 'timeseries',
tick: {
format: "%Y" // https://github.com/mbostock/d3/wiki/Time-Formatting#wiki-format
}
}
}
});
In data, the format of the x axis and the values (in this graphic you have four variables and the x value) are included. You can also format the x axis with the axis key.
I have a c3js line graph of type timeseries.
My axis tables are currently like this:
11/10.....05/11.....11/11.....05/12.....11/12.....05/13.....11/13
and it want it to be
.12/10.....06/11.....12/11.....06/12.....12/12.....06/13.....
where each dot indicates a month, note that the datapoint at 11/10 is still kept and displayed, only the axis labelling has changed. FYI, The increment is not set directly but hacked using culling.
Is there any way to alter the starting label to 12/10 (with all subsequent labels increasing in 6-months intervals)?
UPDATE (14NOV14): I have added a working jsFiddle for you to tinker with. Any help is appreciated!
UPDATE (14NOV14): I have tried using functions for this. But I want the 'pop-up' box to show the grey heading all the time.
This was a painfully long learning process, for a very badly-documented library. But I had to use a function for the format option for the tick, and then format the title again for the tooltip. Here's the final, working copy.
HTML (Include the d3.js, c3.js, and c3.css scripts too)
<body>
<div id="chartContainer"></div>
</body>
JS
var chart = c3.generate({
bindto: '#chartContainer',
data: {
x: 'x',
columns: [
['x', '2013-04-01', '2013-05-02', '2013-06-03', '2013-07-04', '2013-08-05', '2013-09-06'],
['data1', 30, 200, 100, 400, 150, 250],
['data2', 130, 340, 200, 500, 250, 350]
]
},
axis: {
x: {
type: 'timeseries',
tick: {
format: function (x) {
if((x.getMonth()+1) % 6 === 0) {
return ('0' + (x.getMonth()+1)).slice(-2) + '/' + x.getFullYear().toString().substr(2,2);
}
}
}
}
},
tooltip: {
format: {
title: function (d) {
var format = d3.time.format('%m/%y');
return format(d)
}
}
}
});
N.B. Also be aware that culling might interfere with this. I had to set culling: {max: 100} to ensure any built in incrementations are not applied.
