renderer.setSeriesToGroupMap(map);
也就是 org.jfree.chart.renderer.category.BarRenderer3D renderer;
renderer = new org.jfree.chart.renderer.category.BarRenderer3D();
不支持renderer.setSeriesToGroupMap(map);

楼上的这个3D效果是简单的，现在最主要的是在3D下如何处理如下代码
GroupedStackedBarRenderer renderer = new GroupedStackedBarRenderer();
KeyToGroupMap map = new KeyToGroupMap("G1");
Iterator<String> iter2=rowList.keySet().iterator();
String str = "";
int i = 0;
while(iter2.hasNext())
{
Object key=iter2.next();
if(!str.equalsIgnoreCase((String)key))
{
i++;
}
map.mapKeyToGroup(rowList.get(key)+" (得分)", "G"+i);
map.mapKeyToGroup(rowList.get(key)+" (差额)", "G"+i);
}
renderer.setSeriesToGroupMap(map);

另外，针对这个分组柱状图，做成3D效果，我试了很多种办法都不行，有谁实现过的？

你写这个显示没错，但是你到底要显示什么，没说清楚

要显示什么样，这个显示jfreechart官方的模型类型吧

网上看下JFreeChart文档，好像没有设置这个的方法，也只有像lz说的那样，横轴调整成90度显示的办法了。
本来想设置dataSet的时候可以用换行符，比如："产/n品/n一"，试了下不可行，遗憾。。.

domainAxis.setCategoryLabelPositions(CategoryLabelPositions.UP_90);
这个只能改变 Jan 04 这个的现实，不能改变 产品一 这个现实模式。

这是官方模板，目前的产品一 产品二 这三个字是横显
我要让他竖显即如下：
产
品
一
因为这样 柱状图多的时候 文字才显示的清楚
但是 目前SubCategory不知道怎么设置，对Category可以设置成90度显示
