Highcharts 基於web的純javascript圖表庫

背景
本文主要是作爲Highcharts的入門級介紹。和大家分享這個好用的圖標庫，詳情使用方法請訪問http://www.highcharts.me/
Highcharts簡介
Highcharts是一款純Javascript圖表庫，讓開發者很容易在Web網站、Web應用中創建交互性的圖表。Highcharts目前支持line , spline, area, areaspline, column, bar, pie, scatter, angular gauges, arearange,areasplinerange, columnrange, bubble, box plot, error bars, funnel, waterfall 和 polar等各種類型圖表。

兼容性：
Highcharts支持目前所有現在瀏覽器，包括IE6、iPhone/ipad。標準（W3C標準）的瀏覽器用SVG圖形渲染，在遺留的IE瀏覽器中用VML繪圖。
圖表類型豐富

Highcharts目前支持 line , spline, area, areaspline, column, bar, pie, scatter, angular gauges,arearange, areasplinerange, columnrange, bubble, box plot, error bars, funnel, waterfall 和 polar等各種類型圖表。其中很多種圖表可以集成在同一個圖中形成綜合圖。

動態性
提供豐富的API接口方便在創建圖表後對圖表的任意點、線、文字等進行增加、刪除、修改操作。支持衆多的Javascript時間，結合Jquery、MooTools、Prototype 提供的Ajax接口，可以實時的從服務器取得數據並實時刷新圖表。
多軸支持
對於需要比較的數據，Highcharts提供多軸支持。並且每個軸可以方便設置其位置、文字、樣式等。
動態提示框
當鼠標劃過圖表時，Highcharts會顯示信息提示框，顯示當前點的信息，當然，顯示的內容和樣式可以動態指定。
圖表導出和打印功能
你可以將Highcharts圖表導出爲PNG、JPG、PDF、SVG格式文件或直接在網頁上打印出來。
圖表縮放
可以設置圖表的縮放，讓你更方便查看圖表數據。
支持外部數據加載
Highcharts支持多種數據形式，可以是Javascript數組，json文件、json對象、表格等，這些數據來源可以使本地、不同頁面，甚至是不同網站。

運行環境
Highcharts完全基於本地瀏覽器技術，不需要任何插件，比如Flash、java，可以運行在任何現代瀏覽器，包括移動終端以及IE6，標準的瀏覽器用 SVG技術渲染圖表，對於遺留的瀏覽器，則用VML來繪圖。
安裝

Highcharts運行需要兩個js文件，Highcharts.js和 Jquery、MooTools 、Prototype 、Highcharts Standalone Framework 其中的一個框架庫文件。推薦使用Highcharts.js和jquery的組合。

通過CND 引入必須的js文件
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.8.2/jquery.min.js"></script>
<script src="http://code.highcharts.com/highcharts.js"></script>
引入本地js文件
<script src="js/jquery.min.js"></script>
