FusionCharts在Java中的基本使用（2）

五、单序列XML形式

 举例：

<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

（5）Line图

（6）Doughnut图

六、多序列XML形式

举例：

<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

（2）Bar图

（3）Column图

（4）Line图

（5）Stacked图

七、产生上述XML的类

public class FusionChartsXMLGenerator {
	
	public static final int BOOLEAN_TRUE = 0;
	public static final int BOOLEAN_FALSE = 1;
	private static Logger LOGGER = LoggerFactory.getLogger(FusionChartsXMLGenerator.class); 
	
	private static FusionChartsXMLGenerator singleton = new FusionChartsXMLGenerator();
	
	public static FusionChartsXMLGenerator getInstance() {
		return singleton;
	}
	
	private FusionChartsXMLGenerator() {}
	
	private String[] colors = {"AFD8F8", "F6BD0F", "8BBA00", "FF8E46", "008E8E",
			"D64646", "8E468E", "588526", "B3AA00", "008ED6", "9D080D", "A186BE"};
	
	/**

	 * type1 value1,value2,value3,...

	 */

			}
		}

		strXml.append("<categories>");
