This is very vague only. Please explain, what "dividing into block" exactly means. How are the blocks displayed currently? What does "show larger" mean - in a new figure or zoomed inside the current axes, or do you display the blocks in a 2x2 subplot scheme and want to enlarge one axes while shrinking the others?
