Hi everybody,
I've created a 15x15 plot with the boxes showing different colors ranging from dark blue to dark red depending on the connection between x and y. I've been using imagesc.
My question is: Is there a way to make a completely black line across the plot in like (1,1), (2,2), (3,3) and so on?
Best regards,
Eric

img(1:a,1:a)=5;
figure(1)
imagesc(img);
hold on
b=1:a;
plot(b,b,'k');

If you want the line in the overlay above the image, you can simply use line() or plot().
If you want the line "burned into" the image, you can follow my attached demo.
