OFCGWT 入门实例
Web 开发中，主要使用下面两个文件，
- open-flash-chart.swf: Flash 文件接口，通过该文件来生成 Flash 文件，备页面调用(在 web 目录下，与 WEB-INF 目录并级)。
- swfobject.js: Flash 文件依赖的 JS 文件(在 web 目录下，与 WEB-INF 目录并级)。
首先在页面中编写 script 脚本,保存页面为 chart.html
<html>
<head>
<script type="text/javascript" src="js/swfobject.js"></script>
<script type="text/javascript">
swfobject.embedSWF("open-flash-chart.swf", "my_chart", "250", "200", "9.0.0");
</script>
</head>
<body>
<p>Hello World</p>
<div id="my_chart"></div>
</body>
</html>
其次，编写图表的 JSON 文本，将该文本保存为 data.json, 放在与 chart.html 同一个目录下。
{
"title":{
"text": "Many data lines",
"style": "{font-size: 20px; color:#0000ff; font-family: Verdana; text-align: center;}"
},
"y_legend":{
"text": "Open Flash Chart",
"style": "{color: #736AFF; font-size: 12px;}"
},
"elements":[
{
"type": "bar",
"alpha": 0.5,
"colour": "#9933CC",
"text": "Page views",
"font-size": 10,
"values" : [9,6,7,9,5,7,6,9,7]
},
{
"type": "bar",
"alpha": 0.5,
"colour": "#CC9933",
"text": "Page views 2",
"font-size": 10,
"values" : [6,7,9,5,7,6,9,7,3]
}
],
"x_axis":{
"stroke":1,
"tick_height":10,
"colour":"#d000d0",
"grid_colour":"#00ff00",
"labels": ["January","February","March","April","May",
"June","July","August","Spetember"]
},
"y_axis":{
"stroke": 4,
"tick_length": 3,
"colour": "#d000d0",
"grid_colour": "#00ff00",
"offset": 0,
"max": 20
}
}
在浏览器地址栏输入URL，比如：http://localhost:8080/chart/chart.html?ofc=data.json , 就可以看到的图表效果。
