Question

使用JFreeChart 生成一个三维的柱状图，无法显示中文的标题。

JFreeChart chart = ChartFactory.createBarChart3D(
"柱状图", // chart title
"个数no",
"类别no",
dataset, // data
PlotOrientation.VERTICAL ,
false, // include legend
true,
false
);

中文的title不能显示，如柱状图三个字不能显示，横轴和纵轴都只能显示no。发现改成英文可以显示的，如chart.setTitle(new TextTitle("testtesttitle"));。添加语句//chart.setTitle(new TextTitle("柱状图柱状图",new Font("宋体",Font.BOLD+Font.ITALIC,20)));程序会报错说The constructor TextTitle(String, Font) is undefined 求大神解答。。。

你调用这个方法试试看~
//设置乱码字体的,获得相关
public static void getChartTheme(){

StandardChartTheme theme = new StandardChartTheme("unicode") {
public void apply(JFreeChart chart) {
chart.getRenderingHints().put(RenderingHints.KEY_TEXT_ANTIALIASING,
RenderingHints.VALUE_TEXT_ANTIALIAS_OFF);
super.apply(chart);
}
};
theme.setExtraLargeFont(new Font("宋体", Font.PLAIN, 20));
theme.setLargeFont(new Font("宋体", Font.PLAIN, 14));
theme.setRegularFont(new Font("宋体", Font.PLAIN, 12));
theme.setSmallFont(new Font("宋体", Font.PLAIN, 10));
ChartFactory.setChartTheme(theme);
}
