Hi, I have a collection returned from a database of dates and sales volume. I would like to use that collection to display a line chart per day and a bar chart per month How can I take a TimeSeries of class Day and transform it into a TimeSeries of Class Month using jfree or do I need to do that out...

I have a rather large dataset for which I would like to chart a timeline. How can I use a TimeSeries Data set to generate the appropriate data attribute value for an Eastwood base line chart. is there any helper classes I can use

Thanks in advance
