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

(4)Column图
FCF_Column2D.swf FCF_Column3D.swf
(5)Line图
FCF_Line.swf
(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

(2)Bar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"}; /** * data形式为: * "" category1,category2,category3...-------->这是第一行 * type1 value1,value2,value3,... * type2 value1,value2,value3,... * ...... */ public String getMultiDSXML(List<List<String>> data, String caption, String subCaption, String xAxisName, String yAxisName, int showNames,int showValues, int decimalPrecision, int rotateNames) { double max = -Double.MAX_VALUE, min = Double.MAX_VALUE; for (int i = 1; i < data.size(); i++) { List row = (List)data.get(i); for (int j = 1; j < row.size(); j++) { String val = (String)row.get(j); if (val != null && val.length() > 0) { double v = Double.parseDouble(val); if (v > max) { max = v; } if (v < min) { min = v; } } } } if (max == -Double.MAX_VALUE) { max = 0; } if (min == Double.MAX_VALUE) { min = 0; } if (min == max && min == 0) { min = 0; max = 100; } max = Math.abs(max / 10) + max; min = min - Math.abs(min / 10); int valCnt = ((List)data.get(0)).size() - 1; if (valCnt > 30) { showNames = 0; showValues = 0; } StringBuffer strXml = new StringBuffer(); strXml.append("<graph baseFont='SunSim' baseFontSize='12' caption='" + caption +"' subcaption='" + subCaption + "' " + "yAxisMinValue='" + min + "' yAxisMaxValue='" + max + "' " + "xAxisName='" + xAxisName + "' yAxisName='" + yAxisName + "' hovercapbg='FFECAA' " + "hovercapborder='F47E00' formatNumberScale='0' decimalPrecision='" + decimalPrecision + "' " + "showValues='" + showValues + "' numdivlines='10' numVdivlines='0' " + "showNames='" + showNames + "' rotateNames='" + rotateNames + "' " + "rotateYAxisName='0' showAlternateHGridColor='1'>"); strXml.append("<categories>"); List headerRow = (List)data.get(0); for (int i = 1; i < headerRow.size(); i++) { strXml.append("<category name='" + headerRow.get(i) + "'/>"); } strXml.append("</categories>"); for (int i = 1; i < data.size(); i++) { List row = (List)data.get(i); String name = (String)row.get(0); String color = colors[(i - 1) % 12]; strXml.append("<dataset seriesName='" + name +"' " + "color='" + color + "' anchorBorderColor='" + color + "' " + "anchorBgColor='" + color + "'>"); for (int j = 1; j < row.size(); j++) { strXml.append("<set value='" + (String)row.get(j) +"'/>"); } strXml.append("</dataset>"); } strXml.append("</graph>"); String str = strXml.toString(); LOGGER.info("=============/n" + str + "/n==============/n"); return str; } /** * 数据格式为: * name value * name value * ...... */ public String getSingleDSXML(List<List<String>> data, String caption, String subCaption, String xAxisName, String yAxisName, int showNames,int showValues, int decimalPrecision, int rotateNames) { double max = -Double.MAX_VALUE, min = Double.MAX_VALUE; for (int i = 0; i < data.size(); i++) { List<String> row = data.get(i); double value = Double.parseDouble(row.get(1)); if (value > max) { max = value; } if (value < min) { min = value; } } if (max == -Double.MAX_VALUE) { max = 0; } if (min == Double.MAX_VALUE) { min = 0; } if (min == max && min == 0) { min = 0; max = 100; } max = Math.abs(max / 10) + max; min = min - Math.abs(min / 10); int valCnt = data.size() - 1; if (valCnt > 30) { showNames = 0; showValues = 0; } StringBuffer strXml = new StringBuffer(); strXml.append("<graph baseFont='SunSim' baseFontSize='12' caption='" + caption +"' subcaption='" + subCaption + "' " + "yAxisMinValue='" + min + "' yAxisMaxValue='" + max + "' " + "xAxisName='" + xAxisName + "' yAxisName='" + yAxisName + "' hovercapbg='FFECAA' " + "hovercapborder='F47E00' formatNumberScale='0' decimalPrecision='" + decimalPrecision + "' " + "showValues='" + showValues + "' numdivlines='10' numVdivlines='0' " + "showNames='" + showNames + "' rotateNames='" + rotateNames + "' " + "rotateYAxisName='0' showAlternateHGridColor='1'>"); for (int i = 0; i < data.size(); i++) { List<String> row = data.get(i); String label = row.get(0); String value = row.get(1); String color = colors[i % 12]; strXml.append("<set name='" + label + "' value='" + value + "' color='" + color + "'/>"); } strXml.append("</graph>"); String str = strXml.toString(); LOGGER.info("=============/n" + str + "/n==============/n"); return str; } }
