[![NPM](https://nodei.co/npm/kline.png)](https://npmjs.org/package/kline)

> 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](https://webpack.js.org/) 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
