Thanks Duncan for the replyI can not suppress anything these are radiation pattern measurements that are typically are taken at X,Y and Z planes. See an example here, where I want to plot the measurements for the red, green and blue planes (so the image below withouth the 3d green structure inside)https://www.researchgate.net/publication/258391165/figure/fig7/AS:322947316240401@1454008048835/Radiation-pattern-of-Archimedean-spiral-antenna-a-3D-and-b-elevation-cuts-at-phi.png 

I am quite confident that there is a tool in R to help me do this 3D plot, and even better rotatable.
Thanks for the reply to allAlex

You can't easily do what you're trying to do.  You have 6 coordinates to 
display:  the 3 angles and values corresponding to each of them.  You 
need to suppress something.

If the values for matching angles correspond to each other (e.g. x=23 
degrees and y=23 degrees and z=23 degrees all correspond to the same 
observation), then I'd suggest suppressing the angles.  Just do a 
scatterplot of the 3 corresponding values.  It might make sense to join 
them (to make a path as the angles change), and perhaps to colour the 
path to indicate the angle (or plot text along the path to show it).
