JFreeChart生成3D柱状图

1、源码如下：

/**
 * @Title:ColumnChart.java
 * @Package:com.you.jfreechart
 * @Description:柱形图
 * @author:Youhaidong(游海东)
 * @date:2013-7-23 下午10:50:00
 * @version V1.0
 */
package com.you.jfreechart;

import java.awt.Color;
import java.awt.Font;
import org.jfree.chart.ChartFactory;
import org.jfree.chart.ChartFrame;
import org.jfree.chart.JFreeChart;
import org.jfree.chart.axis.CategoryAxis;
import org.jfree.chart.axis.CategoryLabelPositions;
import org.jfree.chart.plot.CategoryPlot;
import org.jfree.chart.plot.PlotOrientation;
import org.jfree.chart.title.LegendTitle;
import org.jfree.data.category.DefaultCategoryDataset;

/**

 * @version V1.0
 */
public class ColumnChart {

	public ColumnChart(String string, JFreeChart chart) {
		
	}

	/**
	 * @Title:main
	 * @Description:柱形图
	 * @param:@param args
	 * @return: void
	 * @throws
	 */
	public static void main(String[] args) {
		
		DefaultCategoryDataset dataset = new DefaultCategoryDataset();
		dataset.addValue(630, "湖北", "香蕉");
		dataset.addValue(520, "湖南", "苹果");
		dataset.addValue(320, "河北", "橘子");
		dataset.addValue(850, "河南", "梨子");
		dataset.addValue(240, "广东", "杏子");
		dataset.addValue(340, "广西", "葡萄");
		dataset.addValue(410, "浙江", "柠檬");
		dataset.addValue(600, "辽宁", "西瓜");
		dataset.addValue(780, "黑龙江", "荔枝");
		
		JFreeChart chart = ChartFactory.createBarChart3D("水果销售分布图","水果", "销量量", dataset, 
				           PlotOrientation.VERTICAL, true, true, false);
		chart.setBackgroundPaint(Color.yellow);
		CategoryPlot categoryPlot = chart.getCategoryPlot();
		categoryPlot.setBackgroundPaint(Color.LIGHT_GRAY);
		categoryPlot.setDomainGridlinePaint(Color.white);
		categoryPlot.setDomainGridlinesVisible(true);
		categoryPlot.setRangeGridlinePaint(Color.white);
		CategoryAxis categoryAxis = categoryPlot.getDomainAxis();
		categoryAxis.setCategoryLabelPositions(CategoryLabelPositions.DOWN_45);
		categoryPlot.getDomainAxis().setLabelFont(new Font("宋体",Font.BOLD,12));
		categoryPlot.getRangeAxis().setLabelFont(new Font("宋体",Font.BOLD,12));
		//解决标题乱码
		chart.getTitle().setFont(new Font("宋体",Font.BOLD,20));
		
		ChartFrame chartFrame = new ChartFrame("水果数量分布", chart);
		chartFrame.pack();
		chartFrame.setVisible(true);
		
		//解决Legend乱码问题
		LegendTitle legendTitle = chart.getLegend(0);
		legendTitle.setItemFont(new Font("宋体",Font.BOLD,12));
        
	}

}

2、生成结果如下，出现乱码：

3、解决中文乱码的源码

public class ColumnChart {

	}

		JFreeChart chart = ChartFactory.createBarChart3D("水果销售分布图","水果", "销量量", dataset, 
				           PlotOrientation.VERTICAL, true, true, false);

		//解决Legend乱码问题
		LegendTitle legendTitle = chart.getLegend(0);
		legendTitle.setItemFont(new Font("宋体",Font.BOLD,12));
        
	}

}

4、显示结果如下图：
