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).
