前言

在大数据时代，数据可视化技术显得至关重要。一个设计优雅的信息图，能在一个600px*400px的画布上，显示出各种行业的全球市场的几百万条数据。

“如果图像能通过数据驱动，如果图像能动起来，如果图像支持交互，如果还能画股票K线图”，那才我想要的。Highchart是一个基于Javascript的跨浏览器的图形可视化工具，能满足我的需求。

1. highchart介绍

Highcharts是一个非常流行界面美观的纯Javascript图表库。它主要包括两个部分：Highcharts和Highstock。

Highcharts能够很简单便捷的在web网站或是web应用程序添加有交互性的图表，并且免费提供给个人学习、个人网站和非商业用途使用。目前HighCharts支持的图表类型有曲线图、区域图、柱状图、饼状图、散状点图和综合图表。

Highstock可以为您方便地建立股票或一般的时间轴图表。它包括先进的导航选项，预设的日期范围，日期选择器，滚动和平移等等。

2. highchart项目构建

系统环境

win7 64bit
Nodejs:v0.10.5
Npm:1.2.19

初始化项目

~ D:\workspace\javascript>mkdir highchart && cd highchart 

~ D:\workspace\javascript\highchart>bower search highchart

我们通过bower来下载highchart库，有关bower的安装和使用，请参考文章：bower解决js的依赖管理

通过Ant工具构建highcharts. Ant是一个用Java开发的自动化构建工具。

~ cd bower_components\highcharts.com

BUILD SUCCESSFUL
Total time: 1 minute 19 seconds

在新生成的build/dist文件夹中，就能找到highchart.js, highstock.js，这两个用于发布的文件了。

用grunt创建一个静态服务器，grunt的使用说明，请参考文章：grunt让Nodejs规范起来

grunt的运行时环境，新建文件：package.json，Gruntfile.js

~ npm install grunt
~ npm install grunt-contrib-connect

~ vi packages.json
{
    "name": "nodejs-highcharts",
    "version": "0.0.1",
    "private": true,
    "scripts": {
        "start": "node app.js"
    },
    "dependencies": {
    },
    "devDependencies": {
        "grunt": "~0.4.1",
        "grunt-contrib-connect": "~0.4.1"
    }
}

~ vi Gruntfile.js
'use strict';
module.exports = function(grunt) {
    grunt.initConfig({
      connect: {
        server: {
          options: {
            port: 9001,
            base: './',
            keepalive: true
          }
        }
      }
    });

    grunt.loadNpmTasks('grunt-contrib-connect');
    grunt.registerTask('server', ['connect']);
};

新建一个测试文件：demo1.html

<!DOCTYPE html>
<html>
<head>
<title>HighCharts</title>
<script src="bower_components/highcharts.com/lib/jquery-1.10.1.js"></script>
<script src="bower_components/highcharts.com/build/dist/highcharts/js/highcharts.js"></script>
</head>
<body>

<div id="container" style="height: 400px"></div>
<script>
$(function () {
Highcharts.setOptions({
colors: ['#058DC7', '#50B432', '#ED561B', '#DDDF00', '#24CBE5', '#64E572', '#FF9655', '#FFF263', '#6AF9C4']
});

$('#container').highcharts({
chart: {
type: 'pie'
},

series: [{
data: [29.9, 71.5, 106.4, 129.2, 144.0, 176.0, 135.6, 148.5, 216.4, 194.1, 95.6, 54.4]
}]
});
});
</script>
</body>
</html>

由于highcharts是依赖于jQuery的，所以我们也需要引入jquery.js

启动grunt server

~ D:\workspace\javascript\highchart>grunt server
Running "connect:server" (connect) task
Waiting forever...
Started connect web server on 127.0.0.1:9001.

浏览器打开：http://localhost:9001/demo1.html

3. highchart使用

找到highchart的官网，查看demo：http://www.highcharts.com/demo/，支持好几十种可视化图形。

我最常用的是曲线图：

新建文件

line.html:网页文件
line.js:脚本文件，进行简单封装
line.json:数据文件

安装moment类库，用于时常日期转换

~ bower install moment

4. highstock使用

到highchart的官网，查看stock demo：http://www.highcharts.com/stock/demo/，同样支持好多种可视化图形。

选择K线图(candlestick)实验：

新建文件：

candlestick.html:网页文件
candlestick.js:脚本文件，进行简单封装
candlestick.json:数据文件

json/candlestick.json, 部分数据
