Problem implementing JFreeChart
提问by Darth Blue Ray
DefaultPieDataset myColoredPieChart = new DefaultPieDataset();
myColoredPieChart.setValue("Java", 12.9);
.......
org.jfree.chart.JFreeChart myColoredChart=ChartFactory.createPieChart("Programming - Colored Pie Chart Example",myColoredPieChart,true,true,false);
I get a error "The type org.jfree.util.PublicCloneable cannot be resolved. It is indirectly referenced from required .class files"
我收到错误消息“无法解析类型 org.jfree.util.PublicCloneable。它是从所需的 .class 文件间接引用的”
Anyone a idea how to fix it?
任何人都知道如何解决它？

JFreeChart is packaged as multiple jar files; you're probably not including all of them in your program. The one named jcommon-XXX.jarcontains the class that's missing, so be sure to inclide that one in your program.
JFreeChart 被打包成多个 jar 文件；您可能没有将所有这些都包含在您的程序中。命名的jcommon-XXX.jar包含缺少的类，因此请确保在您的程序中包含该类。
