I have a 2 dimensional matrix of size 50x200. The matrix is the data set of audio samples(200 samples) which are taken at 50 different locations. I wish to plot this data in a 3D graph where the audio samples are plotted against the locations and time. Also is there a way I can view a 2D plot at a particular location, say x (0<x<50) from the 3D plot I obtain from above? I read a lot of documentation about this but couldn't come up with a logical solution.

Read about surf to plot in 3D....also have a look on pcolor. To plot your desired range read about axis, xlim, ylim and zlim.
