fusionCharts在java的基本应用

一、介绍

FusionCharts是一个基于XML和Flash的图表组件，其中FusionCharts Free是免费的，其功能也十分强大、美观。

在线Demo：http://www.fusioncharts.com/free/demos/Blueprint/

其可以用在PHP、JSP、ASP等等。

二、常见的图表类型

1.Area图

2.Bar图

3.Column图

4.Line图

5.Pie图

6.Stacked图

7.Combine图

三、数据源

其数据源形式为XML的形式，XML形式分为单序列和多序列XML，以及其他的格式。

四、简单使用

目录结构：

test.html

data.xml

FusionCharts

|----------Charts

| |--------------- many charts *.swf

|----------JSClass

| |--------------- FusionCharts.js

test.html代码：

[java]view plaincopy
       
   
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=GBK">
<mce:script language="JavaScript" src="FusionCharts/JSClass/FusionCharts.js" mce_src="FusionCharts/JSClass/FusionCharts.js"></mce:script>
<title>图</title>
</head>
<body>
<table align='center' border="1">
<caption>图</caption>
<tr>
<td>
<div id='Pie' align="center">
<script type="text/javascript">
var chart =
new FusionCharts('FusionCharts/Charts/FCF_Pie2D.swf', "ChartId", "400", "300");
chart.setDataURL("data.xml");
chart.render('Pie');
</script>
</div>
</td>
</tr>
</table>
</body>
</html>

要注意添加以下几行代码，并注意其中的路径：

（1）导入JS： <script language="JavaScript" src='FusionCharts/JSClass/FusionCharts.js '></script>

（2）图表显示的地方：<div id='Pie' align="center">......</div>

（3）脚本：用于设置显示什么图、图的数据等

其中，chart.render("Pie")中的Pie是你要显示图的div的id

data.xml

[xhtml]view plaincopy
       
   
<graph baseFont='SunSim' baseFontSize='12' caption='分析' subcaption='' yAxisMinValue='51650.1' yAxisMaxValue='71118.3' xaxisname='日期' yaxisname='数量' hovercapbg='FFECAA' hovercapborder='F47E00' formatNumberScale='0' decimalPrecision='0' showvalues='1' numdivlines='10' numVdivlines='0' shownames='1' rotateNames='1'>
<set name='2009-10-04' value='57653' color='AFD8F8'/>
<set name='2009-10-05' value='57389' color='F6BD0F'/>
<set name='2009-10-06' value='59256' color='8BBA00'/>
<set name='2009-10-07' value='62762' color='FF8E46'/>
<set name='2009-10-08' value='63287' color='008E8E'/>
<set name='2009-10-09' value='60109' color='D64646'/>
<set name='2009-10-10' value='64653' color='8E468E'/>
<set name='2009-10-11' value='61687' color='588526'/>
</graph>

显示效果如下：

也可以不用单独的文件存储xml，可以利用setDataXML方法，如下：

[c-sharp]view plaincopy
       
   
<script type="text/javascript">
var chart =
new FusionCharts('FusionCharts/Charts/FCF_Pie2D.swf', "ChartId", "400", "300");
chart.setDataXML("<graph baseFont='SunSim' baseFontSize='12' caption='分析' subcaption='' yAxisMinValue='51650.1' yAxisMaxValue='71118.3' xaxisname='日期' yaxisname='数量' hovercapbg='FFECAA' hovercapborder='F47E00' formatNumberScale='0' decimalPrecision='0' showvalues='1' numdivlines='10' numVdivlines='0' shownames='1' rotateNames='1'><set name='2009-10-04' value='57653' color='AFD8F8'/><set name='2009-10-05' value='57389' color='F6BD0F'/><set name='2009-10-06' value='59256' color='8BBA00'/><set name='2009-10-07' value='62762' color='FF8E46'/><set name='2009-10-08' value='63287' color='008E8E'/><set name='2009-10-09' value='60109' color='D64646'/><set name='2009-10-10' value='64653' color='8E468E'/><set name='2009-10-11' value='61687' color='588526'/></graph>");
chart.render('Pie');
<script>

五、单序列XML形式

举例：

[xhtml]view plaincopy
       
   
<graph baseFont='SunSim' baseFontSize='12' caption='分析' subcaption='' yAxisMinValue='51650.1' yAxisMaxValue='71118.3' xaxisname='日期' yaxisname='数量' hovercapbg='FFECAA' hovercapborder='F47E00' formatNumberScale='0' decimalPrecision='0' showvalues='1' numdivlines='10' numVdivlines='0' shownames='1' rotateNames='1'>
<set name='2009-10-04' value='57653' color='AFD8F8'/>
<set name='2009-10-05' value='57389' color='F6BD0F'/>
<set name='2009-10-06' value='59256' color='8BBA00'/>
<set name='2009-10-07' value='62762' color='FF8E46'/>
<set name='2009-10-08' value='63287' color='008E8E'/>
<set name='2009-10-09' value='60109' color='D64646'/>
<set name='2009-10-10' value='64653' color='8E468E'/>
<set name='2009-10-11' value='61687' color='588526'/>
</graph>

<graph>标签的一些属性：

baseFont: 图表的字体

baseFontSize: 图表的字号

caption: 标题

subcaption: 子标题

yAxisMinValue: y轴的最小值

yAxisMaxValue: y轴的最大值

hovercapbg: 当鼠标悬停时显示的背景色

hovercapborder: 当鼠标悬停时边框色

formatNumber（0/1）:是否用逗号分隔（1--用逗号分隔，0--不用）

formatNumberScale（0/1）: 是否添加K、M到数字（1--添加，0--不添加）

decimalPrecision: 小数的位数

showValues（0/1）: 是否显示数值

numdivlines: 水平网格线的条数

numVdivlines: 垂直网络线显示的条数

showNames（0/1）: 是否显示x轴的每个数据的名称

rotateNames（0/1）：是否旋转x轴的每个数据的名称

rotateYAxisName（0/1）：是否显示y轴的名称

showAlternateHGridColor（0/1）：是否显示交替的网格颜色

<set>标签：

name: x轴的每个数据的名称

value: 值

有几种图可以使用单序列的XML格式的数据

（1）Pie图

FCF_Pie2D.swf FCF_Pie3D.swf

（2）Area图

FCF_Area2D.swf

（3）Bar图

FCF_Bar2D.swf

（4）Column图

FCF_Column2D.swf FCF_Column3D.swf

（5）Line图

FCF_Line.swf

（6）Doughnut图

FCF_Doughnut2D.swf

六、多序列XML形式

举例：

[c-sharp]view plaincopy
       
   
<graph baseFont='SunSim' baseFontSize='12' caption='分析' subcaption='' yAxisMinValue='0' yAxisMaxValue='100' xaxisname='地区
' yaxisname='数量' hovercapbg='FFECAA' hovercapborder='F47E00' formatNumberScale='0' decimalPrecision='0' showvalues='1'
numdivlines='10' numVdivlines='0' shownames='1' rotateNames='1' >
<categories font='Arial' fontSize='11' fontColor='000000'>
<category name='N. America' hoverText='North America'/>
<category name='Asia' />
<category name='Europe' />
<category name='Australia' />
<category name='Africa' />
</categories>
<dataset seriesname='Rice' color='FDC12E' alpha='100'>
<set value='30' />
<set value='26' />
<set value='29' />
<set value='31' />
<set value='34' />
</dataset>
<dataset seriesname='Wheat' color='56B9F9' showValues='1' alpha='100'>
<set value='67' />
<set value='98' />
<set value='79' />
<set value='73' />
<set value='80' />
</dataset>
<dataset seriesname='Grain' color='C9198D' showValues='1' alpha='100'>
<set value='27' />
<set value='25' />
<set value='28' />
<set value='26' />
<set value='10' />
</dataset>
</graph>

<graph>基本上同单序列XML形式

<categroies>指明x轴有几个种类

<categroy>对应一个种类

name：种类名

<dataset>指明一个序列集，序列集中值的个数同category的种类数

seriesname：序列的名称

<set>：序列的一个值

有几种图可以使用多序列的XML格式的数据

（1）Area图

FCF_MSArea2D.swf

（2）Bar图

FCF_MSBar2D.swf

（3）Column图

FCF_MSColumn2D.swf FCF_MSColumn3D.swf

（4）Line图

FCF_MSLine.swf

（5）Stacked图

FCF_StackedArea2D.swf

FCF_StackedBar2D.swf

FCF_StackedColumn2D.swf FCF_StackedColumn3D.swf

七、产生上述XML的类

public static final int BOOLEAN_FALSE = 1;

return singleton;
}
