fusionCharts在java的基本应用

 
阅读更多

 

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
 
  1. <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
  2. <html>
  3. <head>
  4. <meta http-equiv="Content-Type" content="text/html; charset=GBK">
  5. <mce:script language="JavaScript" src="FusionCharts/JSClass/FusionCharts.js" mce_src="FusionCharts/JSClass/FusionCharts.js"></mce:script>
  6. <title>图</title>
  7. </head>
  8. <body>
  9. <table align='center' border="1">
  10. <caption>图</caption>
  11. <tr>
  12. <td>
  13. <div id='Pie' align="center">
  14. <script type="text/javascript">
  15. var chart =
  16. new FusionCharts('FusionCharts/Charts/FCF_Pie2D.swf', "ChartId", "400", "300");
  17. chart.setDataURL("data.xml");
  18. chart.render('Pie');
  19. </script>
  20. </div>
  21. </td>
  22. </tr>
  23. </table>
  24. </body>
  25. </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

<script type="text/javascript">
var chart =
new FusionCharts('FusionCharts/Charts/FCF_Pie2D.swf ', "ChartId", "400", "300");
chart.setDataURL("data.xml");
chart.render('Pie ');
</script>

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

 

data.xml

 

[xhtml] view plaincopy
 
  1. <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'>
  2. <set name='2009-10-04' value='57653' color='AFD8F8'/>
  3. <set name='2009-10-05' value='57389' color='F6BD0F'/>
  4. <set name='2009-10-06' value='59256' color='8BBA00'/>
  5. <set name='2009-10-07' value='62762' color='FF8E46'/>
  6. <set name='2009-10-08' value='63287' color='008E8E'/>
  7. <set name='2009-10-09' value='60109' color='D64646'/>
  8. <set name='2009-10-10' value='64653' color='8E468E'/>
  9. <set name='2009-10-11' value='61687' color='588526'/>
  10. </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
 
  1. <script type="text/javascript">
  2. var chart =
  3. new FusionCharts('FusionCharts/Charts/FCF_Pie2D.swf', "ChartId", "400", "300");
  4. 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>");
  5. chart.render('Pie');
  6. <script>

 

五、单序列XML形式

举例:

 

[xhtml] view plaincopy
 
  1. <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'>
  2. <set name='2009-10-04' value='57653' color='AFD8F8'/>
  3. <set name='2009-10-05' value='57389' color='F6BD0F'/>
  4. <set name='2009-10-06' value='59256' color='8BBA00'/>
  5. <set name='2009-10-07' value='62762' color='FF8E46'/>
  6. <set name='2009-10-08' value='63287' color='008E8E'/>
  7. <set name='2009-10-09' value='60109' color='D64646'/>
  8. <set name='2009-10-10' value='64653' color='8E468E'/>
  9. <set name='2009-10-11' value='61687' color='588526'/>
  10. </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
 
  1. <graph baseFont='SunSim' baseFontSize='12' caption='分析' subcaption='' yAxisMinValue='0' yAxisMaxValue='100' xaxisname='地区
  2. ' yaxisname='数量' hovercapbg='FFECAA' hovercapborder='F47E00' formatNumberScale='0' decimalPrecision='0' showvalues='1'
  3. numdivlines='10' numVdivlines='0' shownames='1' rotateNames='1' >
  4. <categories font='Arial' fontSize='11' fontColor='000000'>
  5. <category name='N. America' hoverText='North America'/>
  6. <category name='Asia' />
  7. <category name='Europe' />
  8. <category name='Australia' />
  9. <category name='Africa' />
  10. </categories>
  11. <dataset seriesname='Rice' color='FDC12E' alpha='100'>
  12. <set value='30' />
  13. <set value='26' />
  14. <set value='29' />
  15. <set value='31' />
  16. <set value='34' />
  17. </dataset>
  18. <dataset seriesname='Wheat' color='56B9F9' showValues='1' alpha='100'>
  19. <set value='67' />
  20. <set value='98' />
  21. <set value='79' />
  22. <set value='73' />
  23. <set value='80' />
  24. </dataset>
  25. <dataset seriesname='Grain' color='C9198D' showValues='1' alpha='100'>
  26. <set value='27' />
  27. <set value='25' />
  28. <set value='28' />
  29. <set value='26' />
  30. <set value='10' />
  31. </dataset>
  32. </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

[java] view plaincopy
 
    1. public class FusionChartsXMLGenerator {
    2. public static final int BOOLEAN_TRUE = 0;
    3. public static final int BOOLEAN_FALSE = 1;
    4. private static Logger LOGGER = LoggerFactory.getLogger(FusionChartsXMLGenerator.class);
    5. private static FusionChartsXMLGenerator singleton = new FusionChartsXMLGenerator();
    6. public static FusionChartsXMLGenerator getInstance() {
    7. return singleton;
    8. }
    9. private FusionChartsXMLGenerator() {}
    10. private String[] colors = {"AFD8F8", "F6BD0F", "8BBA00", "FF8E46", "008E8E",
    11. "D64646", "8E468E", "588526", "B3AA00", "008ED6", "9D080D", "A186BE"};
