JFree TimeSeries图表跨越纳秒 [英] JFree TimeSeries Chart Spanning Nanoseconds
问题描述
我必须绘制TimeSeries图表,其中数据以纳秒为单位。但是,在我当前的实现中,我们的日期轴范围是毫秒。
I have to plot TimeSeries chart where the data is coming in nanoseconds. But, In my current implementation our date axis range is in Milliseconds.
所以我如何将日期轴范围从毫秒更改为纳秒。
谢谢。 :)
推荐答案
这是我在您的帖子在JFreeChart论坛中:
This is the answer I gave on your post in the JFreeChart forum:
DateAxis不会为您提供毫秒以下的精度,因为
的底线是与java.util.Date一起使用的(仅提供
毫秒精度)。我认为创建一个可以处理纳秒级的ValueAxis子类不会有任何障碍
,但是
目前没有实现它。
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.
