I'm not sure to understand. Does that mean the user lost the control of
the label angle ?

Some screenshots showing the difference between each solution would
help.

Very nice work indeed.

I have some comments though.

- I'm not sure we really need the 3D-box object. Perhaps the
corresponding control could be moved in the 3d plot panel, while the 3d
view parameters could be stored in the GogChart object (which would be
similar to what's done for the plot area position/size properties).
- It would be nice if the plot could be updated when changing the
parameters.
- The advanced and the rotation tabs could be merged. That would help to
understand which axis psi, theta and phi refer to.
- An isometric view would be great.
- The z axis should not be a discrete axis.
- I would have choosen another approach for the graph layout, where the
user defines the depth of the plot area. At least, it should be possible
to set the z axis length.

        Thanks,
