Answer 1

I had same problem, change your function like below then it will be solved:

function newFigure1(h1, h2)
    figure()
    data = get(h1, 'CData');
    colormap(gray);
    imagesc(data)
end 

Answer 2

The example uses the ButtonDownFcn that can be added to most matlab plot commands. Just copy both functions into one file and run the "interactivePlot" function.

The list_of_images contains all matrices that shall be plotted. The number of matrices is flexible. However, you have to adjust the subplot command...

function interactivePlot
    list_of_images = {rand(5), rand(10), rand(50), rand(100)}

    for ii = 1:length(list_of_images)
        subplot(2,2,ii)
        imagesc(list_of_images{ii}, 'ButtonDownFcn', @newFigure1)
    end
end

function newFigure1(h1, h2)
    figure()
    data = get(h1, 'CData');
    imagesc(data)
end
