Question

I use the following lines of code to plot the images:

for t=1:subplotCol
    subplot(subplotRow,subplotCol,t)
    imagesc([1 100],[1 100],c(:,:,nStep*t));
    colorbar
    xlabel('X-axis')
    ylabel('Y-axis')
    title(['Concentration profile at t_{',num2str(nStep*t),'}'])

    subplot(subplotRow,subplotCol,subplotCol+t)
    hold on;
    plot(distance,gamma(:,1,t),'-ob');
    plot(distance,gamma(:,2,t),'-or');
    plot(distance,gamma(:,3,t),'-og');
    xlabel('h');ylabel('\gamma (h)');
    legend(['\Theta = ',num2str(theta(1))],...
        ['\Theta = ',num2str(theta(2))],['\Theta = ',num2str(theta(3))]);
end

I get the following subplot with images:

As you can see the images in first row are now scaled equally on X and Y axis (Y axis is longer than the X-axis) even though the size of the image matrix is 100×100 for each image on first row.

Can someone help with how to make images in first row look like squares than rectangles which I get currently. Thanks.

Answer 1

Use the dataAspectRatio properties of the axes, and set it to [1 1 1]

%# create a test image
imagesc(1:10,1:10,rand(10))

%# you should use the handle returned by subplot
%# instead of gca
set(gca,'dataAspectRatio',[1 1 1])
