funsionchart利用zoomline现实报表信息，将数据转为XML流--JAVA
1、界面
?
<div id="chart1div"></div>javascript脚本：
?
var chart1 = new FusionCharts("<%=request.getContextPath()%>/FusionCharts/ZoomLine.swf", "0", "1000", "600", "0", "1"); chart1.setDataXML(srcHtml); chart1.render("chart1div"); ??
2、XML类package com.yihaodian.pis.util; import java.io.IOException; import org.dom4j.Document; import org.dom4j.DocumentHelper; import org.dom4j.Element; /** * 使用dom4j生成XML工具类 * * @author 向旗 * */ public class XMLUtil { private Document document = null; public Document getDocument() { return document; } /** * 构造方法，初始化Document */ public XMLUtil() { document = DocumentHelper.createDocument(); } /** * 生成根节点 * * @param rootName * @return */ public Element addRoot(String rootName) { Element root = document.addElement(rootName); return root; } /** * 生成节点 * * @param parentElement * @param elementName * @return */ public Element addNode(Element parentElement, String elementName) { Element node = parentElement.addElement(elementName); return node; } /** * 为节点增加一个属性 * * @param thisElement * @param attributeName * @param attributeValue */ public void addAttribute(Element thisElement, String attributeName, String attributeValue) { thisElement.addAttribute(attributeName, attributeValue); } /** * 为节点增加多个属性 * * @param thisElement * @param attributeNames * @param attributeValues */ public void addAttributes(Element thisElement, String[] attributeNames, String[] attributeValues) { for (int i = 0; i < attributeNames.length; i++) { thisElement.addAttribute(attributeNames[i], attributeValues[i]); } } /** * 增加节点的值 * * @param thisElement * @param text */ public void addText(Element thisElement, String text) { thisElement.addText(text); } /** * 获取最终的XML * * @return * @throws IOException */ public String getXML() { return document.asXML().substring(39); } } ??
3、JAVA增加XML节点内容?
XMLUtil xml = new XMLUtil(); Element graph = xml.addRoot("graph"); xml.addAttribute(graph, "caption", "CPI Category Report"); // xml.addAttribute(graph, "subCaption", "消费者物价指数种类报告"); xml.addAttribute(graph, "basefontsize", "12"); xml.addAttribute(graph, "yAxisName", "价格CPI报表"); xml.addAttribute(graph, "decimalPrecision", "2");// 小数精确度，0为精确到个位 xml.addAttribute(graph, "showValues", "0");// 在报表上不显示数值 xml.addAttribute(graph, "hovercapbg", "FFECAA"); xml.addAttribute(graph, "hovercapborder", "F47E00"); xml.addAttribute(graph, "animation", "1"); xml.addAttribute(graph, "numdivlines", "4"); xml.addAttribute(graph, "numVdivlines", "0"); xml.addAttribute(graph, "numVdivlines", "0"); xml.addAttribute(graph, "yaxisminvalue", "1000"); xml.addAttribute(graph, "yaxismaxvalue", "1800"); xml.addAttribute(graph, "lineThickness", "3"); xml.addAttribute(graph, "rotateNames", "1"); xml.addAttribute(graph, "numberSuffix", "%");增加种类：Element categories = xml.addNode(graph, "categories"); for (int i = 0; i < datelen; i++) { Element category = xml.addNode(categories, "category"); category.addAttribute("name", (new Date(dateMinDate.getTime() + i * 24 * 60 * 60 * 1000)).toString()); }增加种类对应的数据：Element dataset = xml.addNode(graph, "dataset"); xml.addAttribute( dataset, "color", Integer.toString( (int) (Math.random() * 255 * 255 * 255)) .toUpperCase()); xml.addAttribute(dataset, "showValue", "1"); xml.addAttribute(dataset, "alpha", "100"); xml.addAttribute(dataset, "anchorAlpha", "0"); xml.addAttribute(dataset, "lineThickness", "2"); xml.addAttribute(dataset, "seriesname", catNameStrs[i]); for (int m = 0; m < datelen; m++) { Element set= xml.addNode(dataset, "set"); }?4.关于传参的问题传到JAVASCRIPT一方面利用AJAX传参，另一方面利用文本，
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd "> <html xmlns="http://www.w3.org/1999/xhtml "> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>Fusion Chart Test</title> <script type="text/javascript" src="FusionCharts.js"></script> <script type="text/javascript"> function show(){var xml = document.getElementById("test").value;alert(xml); var chart = new FusionCharts("ZoomLine.swf", "0", "800", "600",0,0); chart.setDataXML(xml); chart.render("chartDiv"); } </script></head> <body> <div id="chartDiv"></div> <input type="text" size="500" id="test"/> <input type="button" onclick="show()" value="show"/></body> </html>? (然后按按钮，发现可以安然运行，之所以你先前不行，是因为"与JAVASCRIPT中"有重叠影响。var xml="<graph><categories><category name="1"/><";那么程序只会得到var xml="<graph><categories><category name="后面的会报错，你可以将后台的参数设置在<input type="text" size="500" id="test"/>中<input type="text" size="500" id="test" value="${xml}"/>)在文本框内输入<graph><categories><category name="1"/><category name="1"/><category name="1"/></categories><dataset><set value="5"/><set value="5"/><set value="5"/></dataset></graph> 有不懂的联系QQ526151410
