Hi Moiz, if you are looking for Fourier phase of an image then the below code might help.

% Read the image
img = imread('pout.tif');
img = im2double(img);
% Calculate Fourier phase map
phaseMap = rescale(angle(fft2(img)));
% Visualize results
figure
subplot(1, 2, 1)
imshow(img)
title('Original image')

subplot(1, 2, 2)
imshow(phaseMap)
title('Fourier phase map')

and sir how to plot it in a graph?

[Subhadeep Koley]

I've already displayed the phase image using imshow(). Can you elaborate what kind of graph you're looking for?

[Subhadeep Koley]

Moiz, can you post the error message, which you're encountering?

[moiz shaikh]

sir i need phase angle of image and plot it in graph simply

[moiz shaikh]

Dear sir

now there is no error but i want desired output

[Subhadeep Koley]

Can you provide an example image of your "desired output"?
