first you plot the values in ordinary ex-cell sheet.take snopshot that.if that is under fro image ,so now you apply image in wavelet ,means DWT in image ,i think you may get the anwer 

function showdwt(f,h,z,NJ)

% function showdwt(f,h,NJ,z); Calculates the DWT of periodic f

% with scaling filter h and NJ scales. rag & csb 3/17/94.

% The guts of this program are taken from the program dwt supplied in the book

% Introduction to Wavelets and Wavelet Transforms by Burrus, Gopinath, and Guo.

% Modifications to display the wavelet transform were made by Craig Zirbel.

L = length(f);

c = f(1:2^floor(log(L)/log(2))); % truncate f to a multiple of 2

% this is only to make display easier - CLZ

L = length(c);

M = L/z; % z is the number of data points per unit time

t = [];

if nargin==3, NJ = round(log10(L)/log10(2)); end; % Number of scales

h0 = fliplr(h); % Scaling filter

h1 = h;

h1(1:2:N) = -h1(1:2:N); % Wavelet filter

for j = 1:NJ % Mallat's algorithm

L = length(c);

c = [c(mod((-(N-1):-1),L)+1) c]; % Make periodic

d = conv(c,h1);

d = d(N:2:(N+L-2)); % Convolve & d-sample

c = conv(c,h0);

c = c(N:2:(N+L-2)); % Convolve & d-sample

d=abs(d); % d contains the coefficients

% at the current scale

if NJ-j < 12, % don't display the finest scales

% (they take too long and are

% usually very small anyway)
