In the attached code, I use two separate figure windows.
But how could I bring them under "one" figure?
I guess I have to use subplot() but I'm not sure how to go about it....
Any help is appreciated. This is how my application works : I open up an image in one window and show its projected colors onto a CIE ab diagram. When the user clicks on the image, it draws a circle on the second window. I have not found how to delete the freshly drawn circles between each clicks of the mouse (or do I have to worry about that at all?)

As mentioned by others, there are different ways to achieve the same target.
The attached modified code uses 2 uipanels on one figure.
Noticed that I didn't perform comprehesive tesing on it and some of the items may have positions different from yours.
You may modify again according to your needs.

Hi Roger Breton.
It is my understanding that you want to merge multiple figure windows. Here’s a sample code for that:
[fileNames, filePath] = uigetfile('*.jpg', 'Select JPG files', 'MultiSelect', 'on');
% Check if the selected files are returned as a cell array
if iscell(fileNames)
numFiles = numel(fileNames);
else
numFiles = 1;
fileNames = {fileNames};
end
% Calculate the number of rows and columns for the subplot
numRows = ceil(sqrt(numFiles));
numCols = ceil(numFiles / numRows);
figure;
for i = 1:numFiles
% Construct the full file path
fullFilePath = fullfile(filePath, fileNames{i});
image = imread(fullFilePath);
subplot(numRows, numCols, i);
imshow(image);
% Set the title of the subplot to the corresponding file name
title(fileNames{i});
end
In this example, uigetfile allows the user to select multiple images at a time which is then displayed all together in a single figure window using subplot.
You can refer to the following documentation to know more about the functions used:
