autoFit

{ type: 'view'; options?: FitViewOptions; animation?: ViewportAnimationEffectTiming; } | { type: 'center'; animation?: ViewportAnimationEffectTiming; } | 'view' | 'center'

Whether to automatically fit the canvas. ⚠️ Note: Each time render is executed, it will adapt according to autoFit.

Two basic adaptation modes:

• 'view' - Automatically scale to ensure all content is visible within the view
• 'center' - Center the content without changing the zoom level

More precise adaptation control can be achieved through object form:

const graph = new Graph({
  autoFit: {
    type: 'view', // Adaptation type: 'view' or 'center'
    options: {
      // Only applicable to 'view' type
      when: 'overflow', // When to adapt: 'overflow' (only when content overflows) or 'always' (always adapt)
      direction: 'x', // Adaptation direction: 'x', 'y', or 'both'
    },
    animation: {
      // Adaptation animation effect
      duration: 1000, // Animation duration (milliseconds)
      easing: 'ease-in-out', // Animation easing function
    },
  },
});

FitViewOptions

ViewportAnimationEffectTiming

type ViewportAnimationEffectTiming =
  | boolean // true to enable default animation, false to disable animation
  | {
      easing?: string; // Animation easing function: 'ease-in-out', 'ease-in', 'ease-out', 'linear'
      duration?: number; // Animation duration (milliseconds)
    };

autoResize

boolean Default: false

Whether to automatically resize the canvas.

Implemented based on the window.onresize event. When the browser window size changes, the canvas will automatically resize to fit the container.

background

string

Canvas background color.

This color is used as the background color when exporting images. Any valid CSS color value can be used, such as hexadecimal, RGB, RGBA, etc.

canvas

CanvasConfig

Canvas configuration. Related configuration items under GraphOptions (such as container, width, height, devicePixelRatio, background, cursor) are shortcut configuration items and will be converted to canvas configuration items.

CanvasConfig

container

string | HTMLElement | Canvas

Canvas container, can be one of the following three assignments:

• ID string of the DOM element, such as 'container'
• HTML element object, such as document.getElementById('container')
• Canvas instance, such as new Canvas(options), where options is of type CanvasConfig.

cursor

string

Cursor style, controls the cursor shape when hovering over the canvas. Any valid CSS cursor value can be used.

Supported values include: 'auto', 'default', 'none', 'context-menu', 'help', 'pointer', 'progress', 'wait', 'cell', 'crosshair', 'text', 'vertical-text', 'alias', 'copy', 'move', 'no-drop', 'not-allowed', 'grab', 'grabbing', 'all-scroll', 'col-resize', 'row-resize', 'n-resize', 'e-resize', 's-resize', 'w-resize', 'ne-resize', 'nw-resize', 'se-resize', 'sw-resize', 'ew-resize', 'ns-resize', 'nesw-resize', 'nwse-resize', 'zoom-in', `'zoom-out'.

Cursor values are referenced from MDN - cursor.

devicePixelRatio

number

Device pixel ratio.

Used for high-definition screens, the default is window.devicePixelRatio.

width

number

Canvas width. If not set, the container width will be automatically obtained.

height

number

Canvas height. If not set, the container height will be automatically obtained.

renderer

(layer: 'background' | 'main' | 'label' | 'transient') => IRenderer

Manually specify the renderer

G6 uses a layered rendering approach, divided into four layers: background, main, label, transient. Users can set the renderer for each layer of the canvas through this configuration item.

Example: Use SVG renderer for rendering

import { Renderer as SVGRenderer } from '@antv/g-svg';
import { Graph } from '@antv/g6';

const graph = new Graph({
  renderer: () => new SVGRenderer(),
});

padding

number | number[]

Canvas padding

Usually, during adaptation, it will be adapted according to the padding. It can be a single value (same padding on all sides) or an array form (specify the padding for top, right, bottom, left in order).

Example:

// Single value
const graph1 = new Graph({
  padding: 20, // 20 pixels of padding on all sides
});

// Array form
const graph2 = new Graph({
  padding: [20, 40, 20, 40], // Padding for top, right, bottom, left
});

rotation

number Default: 0

Rotation angle (in radians)

x

number

Viewport x coordinate, sets the initial horizontal position of the viewport.

y

number

Viewport y coordinate, sets the initial vertical position of the viewport.

zoom

number Default: 1

Sets the initial zoom level of the viewport, 1 means 100% (original size).

zoomRange

[number, number] Default: [0.01, 10]

Zoom range, limits the minimum and maximum scale that users can zoom.

animation

boolean | AnimationEffectTiming

Enable or disable global animation

When configured as an animation option, animation will be enabled, and this animation configuration will be used as the base configuration for global animation.

AnimationEffectTiming

Example:

// Simple enable
const graph1 = new Graph({
  animation: true,
});

// Detailed configuration
const graph2 = new Graph({
  animation: {
    duration: 500, // Animation duration (milliseconds)
    easing: 'ease-in-out', // Easing function
  },
});

data

GraphData

Data.

const graph = new Graph({
  data: {
    nodes: [
      { id: 'node1', style: { x: 100, y: 100 } },
      { id: 'node2', style: { x: 200, y: 200 } },
    ],
    edges: [{ id: 'edge1', source: 'node1', target: 'node2' }],
    combos: [{ id: 'combo1', style: { x: 150, y: 150 } }],
