Your question is not clear. When, in Command Windows you type
whos your_variable
What did you get?

Struct arrays can hold any type of data in their fields. So you're going to need to clarify what you mean by plotting a struct. Suppose you had this struct array:
S = struct('x', 1, 'y', 'Steve', 'z', single(magic(5)), 'q', plot(1:10))
What exactly would you want plot(S) to do?
  1. Plot the scalar double from field x
  2. Create a text object displaying the word 'Steve' from field y
  3. Create a surface plot from the single precision array in field z
  4. Copy the line whose handle is stored in field q to a new axes
  5. Multiple or all of the above options 1-4
  6. Something completely different than options 1-5
Now extracting the data from one of the fields and plotting the extracted data works fine.
surf(S.z)
But you need to specifically tell MATLAB that's what you want to do.

The structure includes 3 values. I want to plot every value in the same 2-D plot (ordinate = value and abscissa quantity of values).
I hope that it is clear now.
