<img src="http://www.wtfpl.net/wp-content/uploads/2012/12/wtfpl-badge-4.png" width="80" height="15" alt="WTFPL" />

本项目扒了某网站的K线插件做了一些封装和二次开发,使其更加便于使用和修改,方便后来的开发者. 修改主要涉及以下几个点:

• 使用 webpack 打包 css/images/html
• 使用 ES6 + Babel 对原有代码进行了拆分和重构
• 删除了一些不必要的逻辑
• 把源码中可配置的部分抽出来
• 添加了对 websocket(stomp over websocket) 连接方式的支持
• 增加对外接口及事件回调

Features

✅ 支持两种主题配色切换 
✅ 支持简体中文,英文,繁体中文三种语言 
✅ 可配置的时间聚合方式
✅ 支持多种画线工具
✅ 支持多种画图算法
✅ 支持深度图数据及最近成交数据展示
✅ 支持普通轮询和Websocket Over Stomp两种连接方式
