I create a guide and I use this function to make it full screen:
set(hObject,'units','normalized','outerpos',[0 0 1 1.2]);but i don't get what i want, i get this:
And i want something like this:
MATLAB: How to make a figure full screen

I think the problem is the huge counts at the first and last bins due to masking. Try it this way:
clc; % Clear the command window.
close all; % Close all figures (except those of imtool.)
clear; % Erase all existing variables. Or clearvars if you want.
workspace; % Make sure the workspace panel is showing.
format long g;format compact;fontSize = 15;dicomImagePath = 'mr.jpg';grayImage = imread(dicomImagePath);% Get the dimensions of the image.
% numberOfColorChannels should be = 1 for a gray scale image, and 3 for an RGB color image.
[rows, columns, numberOfColorChannels] = size(grayImage);if numberOfColorChannels > 1 % It's not really gray scale like we expected - it's color.
% Use weighted sum of ALL channels to create a gray scale image.
grayImage = rgb2gray(grayImage); % ALTERNATE METHOD: Convert it to gray scale by taking only the green channel,
% which in a typical snapshot will be the least noisy channel.
% grayImage = grayImage(:, :, 2); % Take green channel.
endsubplot(2, 2, 1);imshow(grayImage,[])axis on;title('Original Grayscale Image', 'FontSize', fontSize, 'Interpreter', 'None');% Set up figure properties:
% Enlarge figure to full screen.
set(gcf, 'Units', 'Normalized', 'OuterPosition', [0, 0, 1, 1]);% Get rid of tool bar and pulldown menus that are along top of figure.
% set(gcf, 'Toolbar', 'none', 'Menu', 'none');
% Give a name to the title bar.
set(gcf, 'Name', 'Demo by ImageAnalyst', 'NumberTitle', 'Off') uiwait(msgbox('Draw over the image'));customROI = imfreehand(gca);mask = customROI.createMask();% Mask the image using bsxfun() function
maskedImage = bsxfun(@times, grayImage, cast(mask, 'like', grayImage));subplot(2, 2, 2);imshow(maskedImage,[])title('Masked Image', 'FontSize', fontSize, 'Interpreter', 'None');subplot(2, 2, 3);histogram(grayImage, 256, 'EdgeColor', 'none')grid on;title('Histogram of Grayscale Image', 'FontSize', fontSize, 'Interpreter', 'None');subplot(2, 2, 4);% Get histogram of masked image, but only within the mask area.
histogram(maskedImage(mask), 256, 'EdgeColor', 'none')grid on;title('Histogram of Masked Image', 'FontSize', fontSize, 'Interpreter', 'None');
Set ( set ) the current figure ( gcf ) to have 'Units' be 'normalized' and the 'outerposition', i.e. the actual borders of the figure to be at the bottom left corner (0,0) and span the whole screen (1,1).
Of you could just run it :)
And look at the doc:
