I added a cursor to a 3d contour plot, which gives location and z value. have displayed as xy projection. when I am moving the cursor, I loose the x and y axis, and the contours become dots.
I don't know if there is a property that can accomplish what you want. I have been playing around with the 3D graphs for quite awhile. I'll keep looking and let you know if I find anything out.
