Accepted Answer

Here's a demo

% Define bound

%bound(1) is the x value of the bottom, left corner of the frame

%bound(2) is the y value for the same corner

%bound(3) is the width of the frame

%bound(4) is the height of the frame

bound = [.2 .1 .5 .7];

% Define grid

x = .3:.1:.6;

y = .2:.1:.7;

% Plot

cla()

xlim([0,1])

ylim([0,1])

hold on

rectangle('position', bound, 'EdgeColor','r')

% Plot vertical lines

vh = plot([x(:),x(:)],[bound(2),sum(bound([2,4]))], 'Color', [.6,.6,.6]);

% Plot horizontal lines

hh = plot([bound(1),sum(bound([1,3]))],[y(:),y(:)], 'Color', [.6,.6,.6])

In my answer, these two lines define the placement of the grid line.

% Define grid

x = .3:.1:.6;

y = .2:.1:.7;

Assuming the image is placed in an axis where the bottom left corner of the axis is (0,0) and the top right corner is (7,9) (rough estimate from your drawing), then you can define the grid lines like this:

interval = 1; %distance between grid lines.

x = linspace(0,7,interval);

y = linspace(0,9,interval);

Give it a try. If you get stuck, share an image (or code) from the actual plot you're working with instead of a drawing.

its not working? can you share sample result with this code?

My answer contains a fully functional sample with this code.

What's not working? What problems are you having? As I mentioned, if you get stuck, share the relevant sections of code (only the relvant sections that plot the grid). And carefully explain what's not working.
