最近信用办项目要将有关统计的平面柱状图改为立体柱状图,用了jfreechart。简单例子,分享一下。
1,首先,引入IText-2.1.5.jar jcommon-1.0.17.jar jfreechart-1.0.14.jar
2,代码
柱状图:
<span style="font-family:KaiTi_GB2312;font-size:18px;">import java.awt.Font; import java.io.File; import org.jfree.chart.ChartFactory; import org.jfree.chart.ChartUtilities; import org.jfree.chart.JFreeChart; import org.jfree.chart.plot.CategoryPlot; import org.jfree.chart.plot.PlotOrientation; import org.jfree.data.category.DefaultCategoryDataset; public class AppBar { public static void main(String[] args) throws Exception { DefaultCategoryDataset ds = new DefaultCategoryDataset(); ds.addValue(2000, "IBM", "一季度"); ds.addValue(2300, "ORACLE", "一季度"); ds.addValue(2800, "JBOSS", "一季度"); ds.addValue(3300, "用友", "一季度"); ds.addValue(4800, "IBM", "二季度"); ds.addValue(4300, "ORACLE", "二季度"); ds.addValue(3200, "JBOSS", "二季度"); ds.addValue(1800, "用友", "二季度"); ds.addValue(1500, "IBM", "三季度"); ds.addValue(2600, "ORACLE", "三季度"); ds.addValue(3900, "JBOSS", "三季度"); ds.addValue(2100, "用友", "三季度"); String title = "前三季度各大公司JEE AS销量统计" ; JFreeChart chart = ChartFactory.createBarChart3D(title, "季度", "销量(单位:万台)", ds, PlotOrientation.VERTICAL, true, false, false); //中文 chart.getTitle().setFont(new Font("宋体", Font.BOLD, 25));//大标题 //提示条 chart.getLegend().setItemFont(new Font("宋体", Font.BOLD, 15)); CategoryPlot plot = (CategoryPlot) chart.getPlot(); //域轴字体 plot.getDomainAxis().setLabelFont(new Font("宋体", Font.BOLD, 18)); plot.getDomainAxis().setTickLabelFont(new Font("宋体", Font.PLAIN, 15));//小标签字体 //range plot.getRangeAxis().setLabelFont(new Font("宋体", Font.BOLD, 15)); plot.setForegroundAlpha(0.6f); ChartUtilities.saveChartAsJPEG(new File("f:\\bar.jpg"), chart, 800, 500); } } </span>
饼图:
