Is the original data available or only the plots?
Are the 2d scatter plot colored by the third axes, such as
pointsize = 14;
subplot(1,3,1)
scatter(x(:), y(:), pointsize, z(:));
subplot(1,3,2)
scatter(x(:), z(:), pointsize, y(:));
because if so then the 3D coordinates can be recovered from any one of them.
If only the 2D information is available, then are the same x, y, and z values used for all of them, in the same order, like
subplot(1,3,1)
scatter(x(:), y(:));
subplot(1,3,2)
scatter(x(:), z(:));
subplot(1,3,3)
scatter(y(:), z(:));
Because if so, if the order is exact and the coordinates match, then the coordinates can be recovered from any two of them.
