XYZ Plots

[StanAccy]

I'm trying to plot 3D data (X/Y graph over a series of days).
While I see that JFreeChart has an XYZDataset (along with a nice comment in the source code about yet-to-be-implemented 3D support), what are the plans, if any, to develop a 3D chart that would be capable of displaying this data?

Is this still a work in progress, or have plans been shelved for this?

Regards

I must have missed this "nice comment".
For 3D data you can use the DefaultXYZDataset or you your own implementation. In order to make the 3rd dimentions visible, you need to assign a suitable renderer to that dataset. Please see

Many thanks for the reply. Ill look into the 3Dbar, but I'm looking to produce a surface plot.

Maybe a bar chart, with a thin enough bar, and clear XY sides (just leaving the top and bottom surfaces filled) will suffice.


A 3D surface plot chart would be a great addition

Hi!

Have a look at David's blog for some ideas about JFreeChart's 3D Supoport:

I did - this is what prompted my initial question. The stuff back last July looked great, but I didn't see any demos of the 3D stuff in the latest JFreeChart.
The graph manipulation in 3D space was especially cool.

However, one of the graph examples on david's blog looked like a surface plot, and this is what I'm trying to achieve here. The discontinuities in the 3D bar graph prevents its use - we are looking for spikes across the plane and a bar chart isn't the easiest format in which to detect these.

I really do want to get back to the 3D stuff, and I expect it to happen this year...but right now I'm working on a few other tasks which are kind of important (to me anyway).

Thanks for the update - I just wanted to check that I wasn't overlooking this functionality in the latest distribution.
