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.

I have a c3.js chart which has 4 datasets. Is it possible to set the tooltop only to display for 1 set of data?
From the code below I only want the tooltip to display for data4.
var chart = c3.generate({
bindto: '#chart3',
data: {
//x: 'x1',
xFormat: '%d/%m/%Y %H:%M', // how the date is parsed
xs: {
'data1': 'x1',
'data2': 'x2',
'data3': 'x3',
'data4': 'x4'
},
columns: [
x1data,
y1data,
x2data,
y2data,
x3data,
y3data,
x4data,
y4data,
],
types: {
data1: 'area',
},
},
legend: {
show: false
}
});
There is the tooltip option for show:false but that disables them all.
Can it display for just 1 dataset?
The tooltip.position() function can be used to control the position of the tooltip, and we can set the tooltip position way off the canvas as a quick hack to hide it when we do not want to see it. However, I do not know how to return the default which is not documented - maybe someone else can elaborate on that.
tooltip: {
grouped: false,
position: (data, width, height, element) => {
if (data[0].id === 'data2'){ // <- change this value to suit your needs
return { top: 40, left: 0 };
}
return { top: -1000, left: 0 };
}
}
EDIT: After digging around for a solution I found that Billboard.js (a fork of C3.js on github) provides a tooltip.onshow() function that the API docs say is 'a callback that will be invoked before the tooltip is shown'. So it would appear that Billboard.js already has the a potential solution where you could intercept the data and hide the tooltip.
I have a C3 chart,
I would like to add a label on each point reading its y value with a percentage symbol appended to it.
e.g. 400%.
There is a solution for bar charts
labels: {
format: {
y: d3.format("$,")
//y: function (v, id) { return "Custom Format: " + id; }
}
But this doesn't work for line graphs.
There is also good answer on custom labels for bar charts, however, this doesn't seem to transfer to line charts.
There is this good answer on custom tooltips, but I can't work out how to do custom labels in a line graph.
Attempt: http://jsfiddle.net/7kYJu/6547/
Also, for some reason using % will prevent the graph from appearing, whereas $ will work, e.g
y: d3.format("$,")
Try This
`var chart = c3.generate({
data: {
columns: [
['data1', 30, 200, 100, 400, 150, 250],
['data2', 130, 100, 140, 200, 150, 50]
],
type: 'line',
labels: {
format: {
data1: d3.format("$,")
//data1: function (v, id) { return "Custom Format: " + id; }
}
}
}
});`
it should be the data array and not the axis to be mentioned as key in format object
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.
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've been struggling with this all morning. While my date's were being dynamically generated by my database, I was defaulting the time to all entries to 8:00AM (as they show in jqplots examples).
The date plots are not only date, but also time sensitive. My solution was to change the default time to 12:01AM for all my plots and now they line up on grid.
I use PHP to dynamically generate my plot arrays as mentioned, they look something like this now:
[chart1] => Array
(
[plots] => ['2013-04-02 12:01AM',11, 11], ['2013-04-03 12:01AM',95, 95], ['2013-04-19 12:01AM',325, 325], ['2013-04-22 12:01AM',90, 90],
)
