If you want a more beautiful animation, you can define your own animation.

Animation Register

Animation register is used to achieve the goal of reusing animation functions. After register, you can use it everywhere.
// require registeration class of animation
const Animate = require('@antv/f2/lib/animation/animate');
* @param {String} animationName Animation name, specified by users
* @param {Function} animationFun define specific animations
Animate.registerAnimation('animationName', animationFun); // register a animation called animationName
// use the registered animation
appear: {
animation: 'animationName' // the registered name of the animation

Details on Custom Animation

F2 provides a complete animation customization mechanism. Users can customize animation behavior for any states of graphic element that supports animation. The states here are the four types of animations: appear, enter, leave, update.
The animations in F2 all act on Shape. The animation is performed by changing shape's attributes frame by frame, take the movement of the circle as example:
The animation is very simple, it moves the circle from point A to point B (the coordinate is {x: 230, y: 50}). We need only to call shape.animate() to specify the final state, i.e. graph attributes, of the shape.
// the initial position of circle on canvas is x: 100, y: 100
attrs: {
x: 230, // final coordinate of x-axis
y: 50 // final coordinate of y-axis
}, // specify the final state of the circle
easing: 'linear', // easing function
duration: 1500 // duration of the animation
See here for graph attributes of various shapes.
Three parameters will be passed to the user-defined animation function, in the order of shape, animateCfg, coord.
appear: {
animation: (shape, animateCfg, coord) => {}
  • shape: The shape instance which animation is acted on.
You can get graph attributes attrs from shape instance and then customize the animation.
The attributes are provided to help users ease the customization:
Method To Get
Get all graph attributes of the shape
Get the type name of the shape
Get the drawing data and corresponding original data record of the shape
Get the index of the shape, i.e. the order of the data record in data set
In addition, shape.attr(name) can also be used to get graph attribute from shape. More methods of shape are listed in Shape API.
F2 also provides a cacheShape attribute for the shape instance in the update state.This attribute stores the content of the previous state for the shape, so that users can customize the animation for changing. The cacheShape contains the following content:
animateCfg: {}, // configuration for animation
attrs: {}, // graph attrs of previous state
className: "", // class name of the shape
  • animateCfg: Object, configuration for animation
    The following attributes are contained in animateCfg:
    easing: , // easing function
    duration: , // duration of the animation
    delay: // delay of the animation
  • coord: Coordinate object, represents the current coordinate of the chart. The attributes contained in coordinate object are listed in Coordinate API.


The example below shows how to customize the apear animation for bar chart, online demo here:
const { Chart, Animate, Util, G } = F2;
// register an animation called delayScaleInY
Animate.registerAnimation('delayScaleInY', function(shape, animateCfg) {
const box = shape.getBBox(); // get the bounding box of the shape
const origin = shape.get('origin'); // get the drawing data of the shape
const points = origin.points; // the points that compose of each column
const centerX = (box.minX + box.maxX) / 2;
let centerY;
if (points[0].y - points[1].y <= 0) { // when the point is below 0
centerY = box.maxY;
} else {
centerY = box.minY;
[ 't', centerX, centerY ],
[ 's', 1, 0.1 ],
[ 't', -centerX, -centerY ]
]); // use matrix transformation to change the origin state of the shape. scaleY.
const index = shape.get('index');
let delay = animateCfg.delay; // get the animation configuration
if (Util.isFunction(delay)) {
delay = animateCfg.delay(index); // set delay time according to the index
const easing = animateCfg.easing; // get the animation configuration
const matrix = shape.getMatrix(); // get the current matrix
const endMatrix = G.Matrix.transform(matrix, [
[ 't', centerX, centerY ],
[ 's', 1, 10 ],
[ 't', -centerX, -centerY ]
]); // the matrix for the final state of the shape
attrs: {
matrix: endMatrix
duration: animateCfg.duration
}); // do the animation
const data = [];
for (let i = 0; i < 50; i++) {
x: i,
y: (Math.sin(i / 5) * (i / 5 - 10) + i / 6) * 5
const chart = new Chart({
id: 'mountNode',
width: 375,
height: 200,
pixelRatio: window.devicePixelRatio
chart.axis('x', false);
.color('y', '#4a657a-#308e92-#b1cfa5-#f5d69f-#f5898b-#ef5055')
.animate({ // customize animation configuration
appear: {
animation: 'delayScaleInY', // use the registered animation name
easing: 'elasticOut', // easing function
delay(index) {
return index * 10;
} // delay time for each shape according to index
