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!!
The value of to[0] is changing dynamically due to a javascript calender. In this code, change event is not working and I don't know...why so???
Jquery Code is:
$(document).ready(function() {
$("input[name='to[0]']").change( function() {
var b1 = $("input[name='to[0]']").val();
alert(b1);
});
});
HTML for this field is:
<td >
<input type="text" size="12" name="to[0]" value="To" readonly="readonly" />
<a class="datepicker" href="#"><img alt="Pick a date" src="js/date.gif" border="0" width="17" height="16" /></a>
</td>

Use this code instead of your code:
$("input:text[name=to[0]]").blur( function() {
var b1 = $(this).val();
alert(b1);
});
As shown on http://jsfiddle.net/RxsL8/1/ change event is never fired for an input if its value is changed dinamycally (and not by explicit user action)
so you would probably need to use some internal function/callbacks provided by your datepicker plugin, or add some code to run when a date is chosen
after your edit:
your input is updated on updateDateField function, right here
if (dateString)
targetDateField.value = dateString;
so add here a callback function
