JFreeChart Timeseries RegularTimePeriod

I can use a TimeSeries to plot 1 minute data using JFreeChart. I'm wondering if there's an easy to plot other time i开发者_Python百科ntervals like 5 min or 15 min, etc? It seems like there are only Minute, Hour, Day, etc. for RegularTimePeriod implementation.

You could introduce a new org.jfree.data.time.RegularTimePeriod, such as PentaMinute or QuarterHour, but I'm skeptical of the usefulness. Alternatively, you might examine the approach adopted for a period of n Millisecond, discussed here and here.
