The existing examples I am able to find use a deprecated version for TimeSeries.
Here's the latest documentation for JFreeChart's TimeSeries:
http://www.jfree.org/jfreechart/api/javadoc/org/jfree/data/time/TimeSeries.html

But, I am not sure ow to implement the same. If possible, please provide me with some example code. Thanks!

This is a demo example without a single deprecated warning - works fine

And if you see a deprectaed warning - don't be afraiid of it - believe me, there is no danger or poison in there.

The above code does not generate deorection - I removed them.
