1、源码如下：

package com.you.jfreechart;
import java.awt.Color;

public class ColumnChart {

}

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

4、显示结果如下图：
