I'm working on a timeline display and I have data that I want to show on the tooltip. currently it only shows the value at each time. and I cannot find a way to change it. the example below shows how to change the value's format but not what values are displayed
var chart = c3.generate({
data: {
columns: [
['data1', 30000, 20000, 10000, 40000, 15000, 250000],
['data2', 100, 200, 100, 40, 150, 250]
],
axes: {
data2: 'y2'
}
},
axis : {
y : {
tick: {
format: d3.format("s")
}
},
y2: {
show: true,
tick: {
format: d3.format("$")
}
}
},
tooltip: {
format: {
title: function (d) { return 'Data ' + d; },
value: function (value, ratio, id) {
var format = id === 'data1' ? d3.format(',') : d3.format('$');
return format(value);
}
//value: d3.format(',') // apply this format to both y and y2
}
}
});
it's taken from http://c3js.org/samples/tooltip_format.html
they do admit that there isn't an example for content editing but I couldn't find anything in the reference or forums, but a suggestion to change the code (it's here: https://github.com/masayuki0812/c3/blob/master/c3.js in line 300) and below:
__tooltip_contents = getConfig(['tooltip', 'contents'], function (d, defaultTitleFormat, defaultValueFormat, color) {
var titleFormat = __tooltip_format_title ? __tooltip_format_title : defaultTitleFormat,
nameFormat = __tooltip_format_name ? __tooltip_format_name : function (name) { return name; },
valueFormat = __tooltip_format_value ? __tooltip_format_value : defaultValueFormat,
text, i, title, value, name, bgcolor;
for (i = 0; i < d.length; i++) {
if (! (d[i] && (d[i].value || d[i].value === 0))) { continue; }
if (! text) {
title = titleFormat ? titleFormat(d[i].x) : d[i].x;
text = "<table class='" + CLASS.tooltip + "'>" + (title || title === 0 ? "<tr><th colspan='2'>" + title + "</th></tr>" : "");
}
name = nameFormat(d[i].name);
value = valueFormat(d[i].value, d[i].ratio, d[i].id, d[i].index);
bgcolor = levelColor ? levelColor(d[i].value) : color(d[i].id);
text += "<tr class='" + CLASS.tooltipName + "-" + d[i].id + "'>";
text += "<td class='name'><span style='background-color:" + bgcolor + "'></span>" + name + "</td>";
text += "<td class='value'>" + value + "</td>";
text += "</tr>";
}
return text + "</table>";
})
did anyone attempted to do so? developed some function to facilitate the process? have any tips on how to do so correctly? I do not know how to change their code in a way I could use more data or data different than the d value the function gets.
If you use the function getTooltipContent from https://github.com/masayuki0812/c3/blob/master/src/tooltip.js#L27 and add it in the chart declaration, in tooltip.contents, you'll have the same tooltip content that the default one.
You can make changes on this code and customize it as you like. One detail, as CLASS is not defined in the current scope, but it's part chart object, I substituted CLASS for $$.CLASS, maybe you don't even need this Object in your code.
var chart = c3.generate({
/*...*/
tooltip: {
format: {
/*...*/
},
contents: function (d, defaultTitleFormat, defaultValueFormat, color) {
var $$ = this, config = $$.config,
titleFormat = config.tooltip_format_title || defaultTitleFormat,
nameFormat = config.tooltip_format_name || function (name) { return name; },
valueFormat = config.tooltip_format_value || defaultValueFormat,
text, i, title, value, name, bgcolor;
for (i = 0; i < d.length; i++) {
if (! (d[i] && (d[i].value || d[i].value === 0))) { continue; }
if (! text) {
title = titleFormat ? titleFormat(d[i].x) : d[i].x;
text = "<table class='" + $$.CLASS.tooltip + "'>" + (title || title === 0 ? "<tr><th colspan='2'>" + title + "</th></tr>" : "");
}
name = nameFormat(d[i].name);
value = valueFormat(d[i].value, d[i].ratio, d[i].id, d[i].index);
bgcolor = $$.levelColor ? $$.levelColor(d[i].value) : color(d[i].id);
text += "<tr class='" + $$.CLASS.tooltipName + "-" + d[i].id + "'>";
text += "<td class='name'><span style='background-color:" + bgcolor + "'></span>" + name + "</td>";
text += "<td class='value'>" + value + "</td>";
text += "</tr>";
}
return text + "</table>";
}
}
});
If you want to control tooltip render and use default rendering depending on data value you can use something like this:
tooltip: {
contents: function (d, defaultTitleFormat, defaultValueFormat, color) {
if (d[1].value > 0) {
// Use default rendering
return this.getTooltipContent(d, defaultTitleFormat, defaultValueFormat, color);
} else {
return '<div>Show what you want</div>';
}
},
format: {
/**/
}
}
In my case i had to add the day for the date value(x axis) in tool tip. Finally i came came up with the below solution

When we have a stacked bar chart and we would like to show "Total" in the tooltip (but not in the chart as a bar/stack) this can come handy.
C3 charts use a array to store the data for tooltips and before the tooltips are displayed we are adding totals (or anyother data as per our requirement). By doing this though the totals is not available as a stack it is shown in the tooltip.
function key_for_sum(arr) {
return arr.value; //value is the key
};
function sum(prev, next) {
return prev + next;
}
var totals_object = {};
totals_object.x = d[0]['x'];
totals_object.value = d.map(key_for_sum).reduce(sum);
totals_object.name = 'total';
totals_object.index = d[0]['index'];
totals_object.id = 'total';
d.push(totals_object);
Above code has been added to ensure that total is available in
C3.js Stacked Bar chart's tooltip
var chart = c3.generate({
/*...*/
tooltip: {
format: {
/*...*/
},
contents: function (d, defaultTitleFormat, defaultValueFormat, color) {
function key_for_sum(arr) {
return arr.value; //value is the key
}
function sum(prev, next) {
return prev + next;
}
var totals_object = {};
totals_object.x = d[0]['x'];
totals_object.value = d.map(key_for_sum).reduce(sum);// sum func
totals_object.name = 'total';//total will be shown in tooltip
totals_object.index = d[0]['index'];
totals_object.id = 'total';//c3 will use this
d.push(totals_object);
var $$ = this,
config = $$.config,
titleFormat = config.tooltip_format_title || defaultTitleFormat,
nameFormat = config.tooltip_format_name || function (name) {
return name;
},
valueFormat = config.tooltip_format_value || defaultValueFormat,
text, i, title, value, name, bgcolor;
for (i = 0; i < d.length; i++) {
if (!(d[i] && (d[i].value || d[i].value === 0))) {
continue;
}
if (!text) {
title = titleFormat ? titleFormat(d[i].x) : d[i].x;
text = "<table class='" + $$.CLASS.tooltip + "'>" + (title || title === 0 ? "<tr><th colspan='2'>" + title + "</th></tr>" : "");
}
name = nameFormat(d[i].name);
value = valueFormat(d[i].value, d[i].ratio, d[i].id, d[i].index);
bgcolor = $$.levelColor ? $$.levelColor(d[i].value) : color(d[i].id);
text += "<tr class='" + $$.CLASS.tooltipName + "-" + d[i].id + "'>";
text += "<td class='name'><span style='background-color:" + bgcolor + "'></span>" + name + "</td>";
text += "<td class='value'>" + value + "</td>";
text += "</tr>";
}
return text + "</table>";
}
}
Adding additional content or non-numerical data into the chart tooltips can be done.
This builds on #supita's excellent answer http://stackoverflow.com/a/25750639/1003746.
Its possible to insert additional metadata about each line into the classes parameter when generating/updating the chart. These can then be added as rows to the tooltip.
This doesn't seem to affect the chart - unless you are using the data.classes feature.
data: {
classes: {
data1: [{prop1: 10, prop2: 20}, {prop1: 30, prop2: 40}],
data2: [{prop1: 50, prop2: 60}'{prop1: 70, prop2: 80}]
}
}
To pick up the metadata in the config.
tooltip: {
contents: function (d, defaultTitleFormat, defaultValueFormat, color) {
const $$ = this;
const config = $$.config;
const meta = config.data_classes;
...
for (i = 0; i < d.length; i++) {
if (! (d[i] && (d[i].value || d[i].value === 0))) { continue; }
if (! text) {
...
}
const line = d[0].id;
const properties = meta.classes[line];
const property = properties? properties[i] : null;
Then add the following rows to the table to show the new properties.
if (property ) {
text += "<tr class='" + $$.CLASS.tooltipName + "-" + d[i].id + "'>";
text += "<td class='name'><span style='background-color:" + bgcolor + "'></span>PROP1</td>";
text += "<td class='name'><span style='background-color:" + bgcolor + "'></span>" + property.prop1 + "</td>";
text += "</tr>";
text += "<tr class='" + $$.CLASS.tooltipName + "-" + d[i].id + "'>";
text += "<td class='name'><span style='background-color:" + bgcolor + "'></span>PROP2</td>";
text += "<td class='name'><span style='background-color:" + bgcolor + "'></span>" +
property.prop2+ " cm/s</td>";
If anybody cares, here is a ClojureScript version of the above algorithm (e.g. supita's answer), slightly simplified (without support for config). (This is probably nothing the OP asked for, but as of now there are so few resources on the net on this topic that most people might wind up here.)
:tooltip {
:contents
(fn [d default-title-format default-value-format color]
(this-as this
(let [this-CLASS (js->clj (.-CLASS this) :keywordize-keys true)
tooltip-name-class (:tooltipName this-CLASS)
rows (js->clj d :keywordize-keys true)
title-row (->> (first rows) (#(str "<table class='" (:tooltip this-CLASS)
"'><tr><th colspan='2'>"
(default-title-format (:x %)) "</th></tr>")))
data-rows (->> rows
(map #(str "<tr class='" tooltip-name-class "--" (:id %) "'>"
"<td class='name'><span style='background-color:"
(color (:id %)) "'></span>" (:name %) "</td>"
"<td class='value'>" (default-value-format (:value %)) "</td>"
"</tr>")))]
(str title-row (string/join data-rows) "</table>"))))}
Your question is about changing the content of the tooltip in c3js.
The tooltip has 3 variables
+----------------+
| title |
+----------------+
| name | value |
+----------------+
Plus, you want to add 'name' from an additional variable, other than those used in 'column'.
tooltip: {
format: {
title(x, index) { return ''; },
name(name, ratio, id, index) { return lst[index + 1]; },
value(value, ratio, id, index) { return value; }
}
},
this worked for me, feel free to play around with the arguments, to get what you need.
I faced a problem which is related tooltip position and style for c3 before. in order to arrange tooltip in c3 freely, my suggestion is manipulating tooltip with d3.
// internal = chart.internal()
const mousePos = d3.mouse(internal.svg.node()); // find mouse position
const clientX = mousePos[0]; //for x
const clientY = mousePos[1]; //for y
const tooltip = d3.select("#tooltip"); //select tooltip div (apply your style)
tooltip.style("display", "initial"); //show tooltip
tooltip.style("left", clientX - mouseOffSet.X + "px"); // set position
tooltip.style("top", clientY - mouseOffSet.Y + "px"); // set position
tooltip.html("<span>" + content + "</span>");
// you can arrange all content and style whatever you want
<div
id="tooltip"
className="your-style"
style={{ display: "none", position: "absolute" }}
/>
Good luck!!

I have this script that a fellow here on the site helped me fix.
This is the first part of the code where you can choose and separate blog articles by tag.
Would it be possible to add CSS in this first part of the code where we have the tags Terror, Shounen, Açãoand make each tag a different color?
For example: Terror: blue - Shounen: yellow - Ação: green
This script pulls the blogger content by the tag, but all columns are the same color, I would like to add a css in each to differentiate them.

Expanding on my comment:
Might be worthwhile to explore using data attributes. Though you could also add a color code attribute to your json, and at a.innerHTML in your javascript section have it do inline css/set the background-color for the div.
It's important to note though, there are likely many solutions to your question, this is just how I'd do it.
Your css file could look something like this:
div[data-tag='Terror'] {
background-color: blue;
}
div[data-tag='Shounen'] {
background-color: yellow;
}
div[data-tag='Ação'] {
background-color: green;
}
and you'd update your javascript to include a data-tag="'+c.feedsUri[c.current].tag+'" on your html element of interest.
The anchor tag may not be where exactly you'd want it, but this would at least get you started in the direction I perceive you're attempting to go.
a.innerHTML = '<div data-tag="'+c.feedsUri[c.current].tag+'" +class="main-title"><h4>' + c.feedsUri[c.current].name + "</h4></div>" + d;
I'm trying to edit the tooltip in a c3 line-chart. Specifically, I need to access the current x-value within the chart.tooltip.format.value function. However, the function is not passed the x-value explicitly.
var chart = c3.generate({
tooltip: {
format: {
value: function (value, ratio, id, index) {
return value;
}
}
},
data: {
x: 'YEAR',
xFormat: '%Y',
url: myURL',
},
axis: {
x: {
type: 'timeseries',
tick: {
format: '%Y'
}
},
},
});
You can use the tooltip's contents property to create a custom tooltip, and in there you can access the X value via: d[0].x.
Edit: use d[0].x.getFullYear() to retrieve only the year part of the date (it's a time series so C3 internally stores the supplied year as a javascript date object)
Here's code I've taken from this discussion https://github.com/c3js/c3/issues/444, and modified:
function tooltip_contents(d, defaultTitleFormat, defaultValueFormat, color) {
var $$ = this, config = $$.config, CLASS = $$.CLASS,
titleFormat = config.tooltip_format_title || defaultTitleFormat,
nameFormat = config.tooltip_format_name || function (name) { return name; },
valueFormat = config.tooltip_format_value || defaultValueFormat,
text, i, title, value, name, bgcolor;
// You can access all of data like this:
//console.log($$.data.targets);
for (i = 0; i < d.length; i++) {
if (! (d[i] && (d[i].value || d[i].value === 0))) { continue; }
// to exclude
//if (d[i].name === 'data2') { continue; }
if (! text) {
title = 'MY TOOLTIP # ' + d[0].x.getFullYear(); // SHOW X-VALUE, year only (given it is a time series)
text = "<table class='" + CLASS.tooltip + "'>" + (title || title === 0 ? "<tr><th colspan='2'>" + title + "</th></tr>" : "");
}
name = nameFormat(d[i].name);
value = valueFormat(d[i].value, d[i].ratio, d[i].id, d[i].index);
bgcolor = $$.levelColor ? $$.levelColor(d[i].value) : color(d[i].id);
text += "<tr class='" + CLASS.tooltipName + "-" + d[i].id + "'>";
text += "<td class='name'><span style='background-color:" + bgcolor + "'></span>" + name + "</td>";
text += "<td class='value'>" + value + "</td>";
text += "</tr>";
}
return text + "</table>";
}
var chart = c3.generate({
data: {
x: 'year',
xFormat: '%Y',
columns: [
['year', '1970', '1975', '1980', '1985', '1990'],
['data1', 100, 200, 150, 300, 200],
['data2', 400, 500, 250, 700, 300],
]
},
axis: {
x: {
type: 'timeseries',
tick: {
format: '%Y'
}
},
},
tooltip: {
contents: tooltip_contents
}
});
My fiddle, showing the current x-value: http://jsfiddle.net/w7h385h3/5/
My Website receives the following string from my WCF Service:
[
{
"Value": 5,
"Color": "#44A9FF",
"HighlightColor": "#5AD3D1",
"Label": "N/A"
},
{
"Value": 79,
"Color": "#009900",
"HighlightColor": "#5AD3D1",
"Label": "On Track"
},
{
"Value": 31,
"Color": "#66FF33",
"HighlightColor": "#5AD3D1",
"Label": "Done"
},
{
"Value": 4,
"Color": "#F3F300",
"HighlightColor": "#5AD3D1",
"Label": "Issue"
},
{
"Value": 7,
"Color": "#FF0000",
"HighlightColor": "#5AD3D1",
"Label": "Behind"
},
{
"Value": 9,
"Color": "#979797",
"HighlightColor": "#5AD3D1",
"Label": "Abandoned"
}
]
But for some reason I can't use $.each but I swear that I've called that on a similar structure before. It just gives me the following error:
Uncaught TypeError: Cannot use 'in' operator to search for 'length' in [{"Value":5,"Color":"#44A9FF","HighlightColor":"#5AD3D1","Label":"N/A"},{"Value":79,"Color":"#009900","HighlightColor":"#5AD3D1","Label":"On Track"},{"Value":31,"Color":"#66FF33","HighlightColor":"#5AD3D1","Label":"Done"},{"Value":4,"Color":"#F3F300","HighlightColor":"#5AD3D1","Label":"Issue"},{"Value":7,"Color":"#FF0000","HighlightColor":"#5AD3D1","Label":"Behind"},{"Value":9,"Color":"#979797","HighlightColor":"#5AD3D1","Label":"Abandoned"}] (10:24:26:561 | error, javascript)

From what I understand I can't use $.each on a string but I thought I made it into an Object. My JavaScript looks like this:
$.getJSON("http://localhost:52535/PUendeligService.svc/GetStatusOverview", function (data) {
var object = $.parseJSON(data);
var parsedData = [];
$.each(object, function () {
var value = object["Value"];
var color = object["Color"];
var highLight = object["HighlightColor"];
var label = object["Label"];
parsedData.push(
{
value: value,
color: color,
highlight: highLight,
label: label
}
);
});
var ctx = $('#myChart').get(0).getContext('2d');
var myPieChart = new Chart(ctx).Pie(parsedData, options);
var myPieChartLegend = $('#pie-chart-legend-tbody');
var tBodyContent = '';
var valueTotal = 0;
$.each(data, function (index) {
var value = data[index]["value"];
valueTotal += value;
});
$.each(data, function (index) {
var value = data[index]["value"];
var color = data[index]["color"];
var label = data[index]["label"];
var element =
'<tr>' +
'<td>' +
'<span class="fa fa-square" style="color:' + color + '"></span>\t' + label +
'</td>' +
'<td>' +
value +
'</td>' +
'<td>' +
((value / valueTotal) * 100).toFixed(2) +
'</td>' +
'</tr>';
tBodyContent += element;
});
tBodyContent +=
'<tr>' +
'<td>Total</td>' +
'<td>' + valueTotal + '</td>' +
'<td>' + 100 + '</td>' +
'</tr>';
myPieChartLegend.html(tBodyContent);
});
The C# code that is run for the example that doesnt't work:
public String GetStatusOverview()
{
StatusOverviewObject soo = new StatusOverviewObject();
soo.Value = 5;
soo.Color = "#44A9FF";
soo.HighlightColor = "#5AD3D1";
soo.Label = "N/A";
StatusOverviewObject soo2 = new StatusOverviewObject();
soo2.Value = 79;
soo2.Color = "#009900";
soo2.HighlightColor = "#5AD3D1";
soo2.Label = "On Track";
StatusOverviewObject soo3 = new StatusOverviewObject();
soo3.Value = 31;
soo3.Color = "#66FF33";
soo3.HighlightColor = "#5AD3D1";
soo3.Label = "Done";
StatusOverviewObject soo4 = new StatusOverviewObject();
soo4.Value = 4;
soo4.Color = "#F3F300";
soo4.HighlightColor = "#5AD3D1";
soo4.Label = "Issue";
StatusOverviewObject soo5 = new StatusOverviewObject();
soo5.Value = 7;
soo5.Color = "#FF0000";
soo5.HighlightColor = "#5AD3D1";
soo5.Label = "Behind";
StatusOverviewObject soo6 = new StatusOverviewObject();
soo6.Value = 9;
soo6.Color = "#979797";
soo6.HighlightColor = "#5AD3D1";
soo6.Label = "Abandoned";
List<StatusOverviewObject> list = new List<StatusOverviewObject>();
list.Add(soo);
list.Add(soo2);
list.Add(soo3);
list.Add(soo4);
list.Add(soo5);
list.Add(soo6);
return JsonConvert.SerializeObject(list);
}
You have 3 $.each in your code.
The first one takes the JSON instance named object and populates the array parsedData just fine.
The problem is in your rest of the iterators, you are passing data(the string of JSON) to them. You should rather pass parsedData instance to them.
$.each(parsedData, function (index) { //"parsedData" instead of "data"
var value = this[index]["value"]; //you can use "this" to access the object passed in argument
valueTotal += value;
});
$.each(parsedData, function (index) { //"parsedData" instead of "data"
var value = this[index]["value"];
var color = this[index]["color"];
var label = this[index]["label"];
var element =
'<tr>' +
'<td>' +
'<span class="fa fa-square" style="color:' + color + '"></span>\t' + label +
'</td>' +
'<td>' +
value +
'</td>' +
'<td>' +
((value / valueTotal) * 100).toFixed(2) +
'</td>' +
'</tr>';
tBodyContent += element;
});
In jquery, I am trying to get the text from a textarea tag, with the new lines as \n and not br tags. The problem is if I select it and get its val, the firefox debugger does not even show the \n or br. If I alert it, then I see there is two lines, but then if I insert it into the DOM, it removes all the new lines. I want it to keep its new lines.
I get it like this:
var handleSend = function(thread_id) {
var user = GLOBAL_DATA.user;
$(context).find("#message-form").unbind('submit').submit(function() {
var field = $(this).find("textarea");
runAJAXSerial($(this).serialize(), {
page : 'message/setmessage',
id : user['id'],
thread_id : thread_id
}, function(response) {
var user = GLOBAL_DATA.user;
var obj = {
user_id : user['id'],
message : field[0].value.replace(/<br\s*\/?>/mg,"\n"),
date_sent : getDate() + ' ' + getTime()
};
alert(obj.message);
cleanResponse(obj);
field.val("").focus();
displayMessages([obj], true);
}, function(data,status,xhr) {
});
return false;
});
};
function cleanResponse(response) {
if (Object.prototype.toString.call( response ) === '[object Array]') {
var i = 0, l = response.length;
for (i=0; i<l; i+=1) {
response[i] = cleanResponse(response[i]);
}
} else if (Object.prototype.toString.call( response ) === '[object Object]') {
for (var property in response) {
if (response.hasOwnProperty(property)) {
response[property] = cleanResponse(response[property]);
}
}
} else {
response = escapeHTML(response);
}
return response;
}
function escapeHTML(str) {
return $("<p/>").text(str).html();
}
var displayMessages = function(response, onBottom) {
var user = GLOBAL_DATA.user, i=0, l=response.length, acc = '';
for(i=0; i<l; i+=1) {
var obj = response[i];
var acc_temp = "";
acc_temp += '<div class="message ' + (obj['user_id']==user['id'] ? 'message-right' : 'message-left') + '">';
acc_temp += '<img src="' + getImage(obj['user_id']) + '" align="right" class="message-image" />';
acc_temp += '<div>' + Autolinker.link(obj['message']) + '</div>';
acc_temp += '<br/>';
if (obj['user_id']!=user['id']) {
acc_temp += '<div class="message-details">' + obj['first_name'] + ' ' + obj['last_name'] + '</div>';
}
acc_temp += '<div class="message-details">' + obj['date_sent'] + '</div>';
acc_temp += '</div>';
acc = acc_temp + acc;
}
addMessage(acc, onBottom);
};
var addMessage = function(html, onBottom) {
var list = $(context).find("#message-list");
if (onBottom) {
list.append(html);
scrollBot();
} else {
list.prepend(html);
}
};
displayMessages inserts the text into the DOM.
cleanResponse encodes the text so that the user can't execute scripts.
Does anyone know whats wrong?
Thanks
New lines in the DOM are treated like any other whitespace. You are getting the expected behaviour of adding the new lines.
If you want an new line to be rendered then you need to use a <br> element or modify the white-space CSS property.

When I run the program it only reads one of the variables i.e. either 1 or 2.
How can I correct them to read both the variables?
Use this.
<script type="text/javascript">
window.onload = function() {
variable1.init();
variable2.init();
}
</script>
Try this
<body onload="callFunctions()">
JS-
function callFunctions()
{
variable1.init();
variable2.init();
}
Update-
Also
there are other different ways to call multiple functions on page load
Hope it hepls you.
