Dear Jos

Thanks very much.

Just a thought - how does the 3D graphing program work ?

Does it create Slices or TIN's ?

Could I create a a dome shape with a hole in it to replicate a cylinder going vertically downwards from a dome shape ?

Micky

regards

Micky

I think it will require quite some work to implement these vertical
cilinders in the 3d view.
 
What may be less work is to extend the Graph3D such that you can select
data points in it, and when a data point is selected, draw the
corresponding vertical cilinder right from the 3d graph.
 
For your application it may be interesting to see if it is easy to realize
with WebGL (for example using three.js <http://threejs.org/>), that will be
more flexible in this regard.

I'm not sure what you mean.

The Graph3D doesn't use real 3D drawing but simulates it on a 2d canvas. Sure you can simulate a 3D cilinder in 2D as well. At some point though it may be easier to go for a real 3D solution.
