概述
基于echarts的股票K线图展示，只需引用单个插件，通过简单配置，导入数据，即可实现炫酷复杂的K线图效果。
详细
一、概述
这是一个简单的股票K线图展示，利用echarts第三方进行配置，用户可以进行放大缩小查看K线图，还可进行拖拽。
二、演示效果
三、目录结构
其中dist文件夹是echart插件，jquery的引用是为了打开网页后F11自适应全屏
四、详细步骤
1、meta标签配置
<meta name="viewport" content="width=device-width, initial-scale=1.0, maximum-scale=1.0, user-scalable=0">
<meta http-equiv="X-UA-Compatible" content="IE=edge,chrome=1"/>
2、文件引用
<script src="dist/echarts.min.js"></script>
<script src="jquery-1.10.1.min.js"></script>
3、添加全局样式，图表容器
<style>
*{margin:0;padding:0}
html,body{ width:100%;
height:100%;
}
#main{
width:100%;
height:100%;
}
</style> <div id="main"></div> //获取容器，建立实例
var myChart = echarts.init(document.getElementById('main'))
myChart.setOption(option);
4、数据格式解释
var rawData = [
['2015/12/31','3570.47','3539.18','-33.69','-0.94%','3538.35','3580.6','176963664','25403106','-'],
['2015/12/30','3566.73','3572.88','9.14','0.26%','3538.11','3573.68','187889600','26778766','-'],
['2015/12/29','3528.4','3563.74','29.96','0.85%','3515.52','3564.17','182551920','25093890','-'],
['2015/12/28','3635.77','3533.78','-94.13','-2.59%','3533.78','3641.59','269983264','36904280','-'],
['2015/12/25','3614.05','3627.91','15.43','0.43%','3601.74','3635.26','198451120','27466004','-']
]
其中数据格式为数组形式的数组，
各个位置的含义：时间 开盘 关盘 最低点 最高点 MA5 MA10 MA20 MA30，后续的几个MA*的意思的最近*天的日均值

showSymbol: false,
lineStyle: {
normal: {

}
}
]
};tooltip、legend：定制信息提示框的内容样式
xAxis和yAxis表示横坐标和纵坐标的数据设置以及样式，这里是调用了两个map循环进行设置，ES6语法，不懂的同学可以先学习一下，毕竟现在ES6还是一个大趋势。
series：整体配置 其中type很关键 表示该图的类型，
data:图表所用数据，实际项目中大家可以通过http获取数据，再赋值给data。
其中lineStyle表示线条样式设置 areaStyle表示块的样式设置。
最后给大家讲一下运用jquery的全屏配置
setInterval(function () {
var maxHeight= $(document.body).outerHeight(true);
$("#main").height(maxHeight);
},1)这个要看实际项目中的需要了，有时候需要将屏幕投影的时候全屏肯定是比一个网页要舒服。大家赶紧下载玩玩吧！
