You can use r libraries for 3 D plotting.
Steps are:
First create a data frame using data.frame() command.
Create a 3D plot by using scatterplot3D library.
Or You can also rotate your chart using rgl library by plot3d() command.
Alternately you can use plot3d() command from rcmdr library.
In MATLAB, you can use surf(), mesh() or surfl() command as per your requirement.
