plotting many 2D plots on one 3D graph
in [Matlab]
|
From: Monica Chon on 15 Jul 2010 09:31 Hi, I am very new to matlab. I have made many 2D-power spectrum plots of frequency vs. amplitude on matlab from data. In fact I have 64 seperate plots, each one showing a plot from select files of data from a series of planes numbered 0-63. So the first plot is plane 0, the second, is plane 1 and so on. I wanted to plot all 64 of these plots in one 3D-plot with the new z-axis being the planes. So the first 2D power spectrum plot would be on 0 of the z-axis, the second would be on 1 of the z-axis and so on. Basically I want to combine the files of data of the planes into a variable on the z-axis so that I can plot my data in 3D. I hope that makes some sense. I would appreciate any help on this task I can't figure out how to do. Thanks

Except my freq=0:2*10^4. Unfortunately I can't figure out how to get my data to appear that way. Do you know how to combine all my data files in order to make the planes 0-63 appear on different numbers on the z-axis. Sorry, if i'm asking obvious questions, I'm really new to matlab. Thanks

You might have some luck starting here: http://matlabwiki.mathworks.com/MATLAB_FAQ#How_can_I_process_a_sequence_of_files.3F If you already know how to read them into a Matlab array, then simply read all 64 files into rows of a single 2D array.
