I want to create a 32 by 32 grid as shown below.
And I also want to add two labeling in x and y directions.
1) 0 - 31 (grid number)
2) 0- 1 (box unit)
I a next slide I have to draw a new box starting from grid number 8 and ends on the grid number 23.
And in the next level I have to add another box which has to start from grid number 12 and should end on grid number 19.
Is there any method to accomplish this ? I tried with TikZ
\draw and \fill
commands. But not giving any desirable result. Please suggest any method to achieve this.
