java - 跨纳秒的 JFree TimeSeries 图表

Question

我必须绘制时间序列图表，其中数据以纳秒为单位。但是，在我当前的实现中，我们的日期轴范围以毫秒为单位。

那么如何将日期轴范围从毫秒更改为纳秒。

谢谢。 :)

Answer 1

这是我在your post上给出的答案在 JFreeChart 论坛中:

The DateAxis won't give you precision below milliseconds, because under the covers it is working with java.util.Date (which provides only millisecond precision). I don't think there would be any obstacle to creating a ValueAxis subclass that could handle nano-seconds, but there is no implementation of that at present.
