Mix 3D scatter plot with other charts

Post by Qingzhi » Fri Oct 21, 2016 11:22 pm

Hi,
Does any one know how to mix 3D Scatter plot with 3D line chart or a surface? In 2D JfreeChart, we just need to call setDataset() method to add several different dataset, but I really don't know how to achieve 3D combination of different charts.

Thanks in advance.

Hi,

I didn't implement the same multi-dataset / multi-renderer feature that JFreeChart has because the 3D rendering approach in Orson Charts (painters algorithm) would result in too many artefacts showing up if multiple datasets were rendered on the same chart.

Do you have any plan to add this feature to combine different 3D datasets?
I just need to show 3D scatter plot with a simple fitting line or surface.

I'm not planning to do it. It wouldn't be hard to add this feature, but I think the rendering issues would make it not very useful. Your particular use case might be OK, but the general case I think wouldn't.
