FusionCharts在Java中的基本使用（2）

五、單序列XML形式

舉例：

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

<graph>標籤的一些屬性：

baseFont: 圖表的字型

baseFontSize: 圖表的字型大小

caption: 標題

subcaption: 子標題

yAxisMinValue: y軸的最小值

yAxisMaxValue: y軸的最大值

hovercapbg: 當滑鼠移至上方時顯示的背景色

hovercapborder: 當滑鼠移至上方時邊框色

formatNumber（0/1）:是否用逗號分隔（1--用逗號分隔，0--不用）

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

decimalPrecision: 小數的位元

showValues（0/1）: 是否顯示數值

numdivlines: 水平網格線的條數

numVdivlines: 垂直網路線顯示的條數

showNames（0/1）: 是否顯示x軸的每個資料的名稱

rotateNames（0/1）： 是否旋轉x軸的每個資料的名稱

rotateYAxisName（0/1）：是否顯示y軸的名稱

showAlternateHGridColor（0/1）： 是否顯示交替的網格顏色

 

<set>標籤：

name: x軸的每個資料的名稱

value: 值

 

有幾種圖可以使用單序列的XML格式的資料

（5）Line圖

（6）Doughnut圖

六、多序列XML形式

舉例：

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

 

<graph>基本上同單序列XML形式

<categroies>指明x軸有幾個種類

<categroy>對應一個種類

name：種類名

<dataset>指明一個序列集，序列集中值的個數同category的種類數

seriesname：序列的名稱

<set>：序列的一個值

七、產生上述XML的類

public class FusionChartsXMLGenerator {</p><p>public static final int BOOLEAN_TRUE = 0;<br />public static final int BOOLEAN_FALSE = 1;<br />private static Logger LOGGER = LoggerFactory.getLogger(FusionChartsXMLGenerator.class); </p><p>private static FusionChartsXMLGenerator singleton = new FusionChartsXMLGenerator();</p><p>public static FusionChartsXMLGenerator getInstance() {<br />return singleton;<br />}</p><p>private FusionChartsXMLGenerator() {}</p><p>private String[] colors = {"AFD8F8", "F6BD0F", "8BBA00", "FF8E46", "008E8E",<br />"D64646", "8E468E", "588526", "B3AA00", "008ED6", "9D080D", "A186BE"};</p><p>/**<br /> * data形式為:<br /> * "" category1,category2,category3...-------->這是第一行<br /> * type1 value1,value2,value3,...<br /> * type2 value1,value2,value3,...<br /> * ......<br /> */<br />public String getMultiDSXML(List<List<String>> data,<br />String caption, String subCaption,<br />String xAxisName, String yAxisName,<br />int showNames,int showValues,<br />int decimalPrecision, int rotateNames) {<br />double max = -Double.MAX_VALUE, min = Double.MAX_VALUE;<br />for (int i = 1;
