Hi,
i wrote the classes to implement plotting of data that
represent wind values (intensity,direction),
and incorporated them in (well my

) jfreechart0.6.0.
If anyone is interested (David?) i'd be glad to send over the code.

Hi Achilleus,
Code submissions are always welcome. Just e-mail me the changes you have made and I'll see if I can integrate it into a future release...
Regards,
DG.

Yes, I would be interested in wind plot. How do I go about getting a copy

Hi All,
I have today (finally!) integrated the code that has been kindly contributed by Achilleus Mantzios. It is a sort of time series plot, that shows the wind force (on the Beaufort scale of 0-12) and direction at various points in time.
The code will be included with version 0.7.2 of JFreeChart, which will be released as soon as I complete a couple more bug fixes...
Regards,
Dave Gilbert

Hi,
I am trying to draw a time series plot. The plot consists of data measured every four minutes. Hence it contains 360 points every day. I typically have data for a week.
I want to show 1-day of data at a time using scrollbar in the plot.
Hence my question is that:
1. How do you show only part of x-axis and let the user scroll towards the end.

Actually, I'd be interested in that too. Do you have a solution for that already?
My idea is to have a scroll bar at the bottom, to scroll the chosen window right and left, and a slider at the top to increase/decrease the time period in the viewport.
For the moment, I think I'll do it with a drop-down box above the window and use the zoom functions. Even though I haven't really looked into it yet...

Hi everyone,
THis is actually very easy to implement on your own. Just make your dataset return only the last n points. I've implemented this in my own code, and even made it switchable so that you can select "last n points" or "all" data.
