## 安装 ```bash npm install @antv/g2 ``` ## 快速开始 ```html
``` ```js import G2 from '@antv/g2'; const data = [ { genre: 'Sports', sold: 275 }, { genre: 'Strategy', sold: 1150 }, { genre: 'Action', sold: 120 }, { genre: 'Shooter', sold: 350 }, { genre: 'Other', sold: 150 }, ]; const chart = new G2.Chart({ container: 'c1', width: 500, height: 500 }); chart.source(data); chart.interval().position('genre*sold').color('genre'); chart.render(); ``` [更多示例](https://antv.alipay.com/zh-cn/g2/3.x/demo/index.html) ## 本地开发 ```bash $ npm install # 跑测试用例 $ npm run test-live # 监听文件变化构建,并打开 demo 页面 $ npm run dev # 打开 demo $ npm run demos ``` ## 如何贡献 如果您在使用的过程中碰到问题,可以先通过 [issues](https://github.com/antvis/g2/issues) 看看有没有类似的 bug 或者建议。 如需提交代码,请遵从我们的[贡献指南](https://github.com/antvis/g2/blob/master/CONTRIBUTING.md)。
