问题描述
我已经使用JFreeChart制作了以下图表：
I've got the following chart made with JFreeChart:alt text http://img706.imageshack.us/img706/912/jfreechart.jpg
是否有可能（如果是这样的话）延长日期在x轴上，以便它们包含年份，例如。 4-II-2010,5-II-2010，...，6-III-2010？
Is it possible (and if it is how) to extend the dates on the x-axis so that they contain the year, eg. 4-II-2010, 5-II-2010, ..., 6-III-2010?
推荐答案
目前尚不清楚你现在如何格式化日期，但 /jfree/chart/axis/DateAxis.html\"rel =nofollow noreferrer> DateAxis 允许您指定合适的。如果尚未提供，您应该能够覆盖 /text/DateFormatSymbols.htmlrel =nofollow noreferrer> DateFormatSymbols 罗马数字。
It's not clear how you are formatting the dates now, but setDateFormatOverride in DateAxis allows you to specify a suitable SimpleDateFormat. If not already available, you should be able to override getShortMonths() in DateFormatSymbols for the Roman numerals.
附录：为了正确本地化，可能更容易做到这样的事情：
Addendum: For correct localization, it may be easier to do something like this:
DateAxis axis = (DateAxis) plot.getDomainAxis();
DateFormatSymbols dfs = DateFormatSymbols.getInstance(); // default locale
String[] roman = { ... };
dfs.setShortMonths(roman);
axis.setDateFormatOverride(new SimpleDateFormat("dd-MMM-yyyy", dfs));
