中文 README

F2 is born for mobile, developed for developers as well as designers. It is Html5 Canvas-based, and is also compatible with Node.js, Weex and React Native. Based on the grammar of graphics, F2 provides all the chart types you'll need. Our mobile design guidelines enable better user experience in mobile visualzation projects.

Special thanks to Leland Wilkinson, the author of The Grammar Of Graphics, whose book served as the foundation for F2 and G2.

Installation

$ npm install @antv/f2

Features

Born for mobile

  • Design for mobile: make data more alive and chart interactions more natural.

  • Performance: small package size(version without interaction is 44k after gzip) with great rendering performance.

  • Compatibility: multi-end, Multi-runtime support. Besides H5 env, F2 can also run in Node.js, Weex rendering and React Native, also 支付宝小程序 and 微信小程序.

All the chart types you want

With the power of grammar of graphics, F2 supports data-driven 50+ chart types(the amount can be even more, which is depended on you) including classical charts such as line, column/bar chart, pie chart, scatter plot, gauges, etc. Additionally, F2 also provides feature-riched chart components, such as Tooltip, Legend and Guide.

Flexible and Interactive

Getting Started

<canvas id="mountNode"></canvas>
// F2 对数据源格式的要求，仅仅是 JSON 数组，数组的每个元素是一个标准 JSON 对象。
const data = [
  { genre: 'Sports', sold: 275 },
  { genre: 'Strategy', sold: 115 },
  { genre: 'Action', sold: 120 },
  { genre: 'Shooter', sold: 350 },
  { genre: 'Other', sold: 150 },
];

// 获取 canvas context
const context = document.getElementById('mountNode').getContext('2d');
const { props } = (
  <Canvas context={context} pixelRatio={window.devicePixelRatio}>
    <Chart data={data}>
      <Axis field="genre" />
      <Axis field="sold" />
      <Interval x="genre" y="sold" color="genre" />
      <Tooltip />
    </Chart>
  </Canvas>
);

const canvas = new Canvas(props);
canvas.render();
