@antv/coord

@antv/coord

Toolkit for mapping elements of sets into geometric objects. (demo)

✨ Features

• Powerful: Not only does @antv/coord provide some basic affine transformations(translate, rotate, scale, etc.), it also provide some advanced coordinate system transformations(polar, helix, parallel) and cool fisheye transformations.
• Fixable: It is a independent lib which means you can use it with other libs besides G2, such as D3 to create some awesome charts and animations.
• Fully embrace TypeScript: All code are written in TypeScript and complete type definition files are provided.

📦 Installation

$ npm install @antv/coord

🔨 Getting Started

import { Coordinate, Options } from '@antv/coord';

const optons: Options = {
  x: 0,
  y: 0,
  width: 500,
  height: 500,
  transformations: [['cartesian']]
};

const coord = new Coordinate(options);
coord.transform('translate', 10, 10);
coord.map([0.5, 0.5]); // [260, 260]
coord.getSize(); // [500, 500]
coord.getCenter(); // [250, 250]
