billboard.js 1.11.0 release: Lazy render, new TextOverlap plugin & more!

What’s New?

Lazy Rendering

The lazy rendering functionality make render lazily when chart bind element visibility is hidden. And when element turn to be visible, automatically renders the chart.

Lazy Rendering in action
// (1) Initial state
<div id='chart' style='display:none'></div>
// (2) Generate chart as usual, but it won't be rendered until '#chart' element visibility change automatically.
const chart = bb.generate({
bindto: "#chart",
// (3) Update the visibility to make chart to be rendered
document.getElementById('chart').style.display = 'block';
render: {
lazy: true, // Make to not render at initialization
observe: false // Observe bind element's visibility

new TextOverlap Plugin

The new “TextOverlap” plugin prevents label text overlap using Voronoi layout from the excellent contribution by github/kimberlybaum!

(Left) Normal positioning / (Right) TextOverlap Plugin applied
const chart = bb.generate({
data: {
columns: [ ... ]
plugins: [
new bb.plugin.textoverlap({
// selector for data label text nodes
selector: ".bb-texts text",
// extent of label overlap prevention
extent: 8,
// minimum area needed to show a data label
area: 3


New startingAngle option for donut & pie, gives the control of start angle where it draws.

pie’s startingAngle option
donut: {
startingAngle: 0.7
pie: {
startingAngle: 1


The axes options for x, y and y2 Axis, makes to add multiple axes for each Axis. But the added Axes’ tick scales was bound to its main Axis, where making harder if you need display different scale than its original value.

x Axes with domain option and y Axes without.
[x|y|y2]: {
axes: [
// set new domain value
domain: [0, 1000],

Improved data.labels.position

data.labels.position option makes positioned data label texts in different position relatively its original position.

Different data label text position for each data
position: {
data1: {x: 5, y: 5},
data2: {x: 10, y: -20}


Added new background option, where you can add background’s image or colred background.

Image background and colored background
background: {
class: "myClass",
color: "red",
// Set image url for background.
// If specified, 'color' option will be ignored.
imgUrl: "",


The data.onover/out option callback has a small improvement. From this reelase, the callback will receive second argument.

data: {
onover/out: function(d, element) {
// d - ex) {x: 4, value: 150, id: "data1", index: 4}
// element - <circle>
