how to avoid overlapping of 2 images

I have 2 images whose boundary are extracted.

I have them plotted.But they are overlapping

this is the code

how to correct it

if true

    %Leveling Y axis

[ymin mindx] = max(Temp_boundary(:,1));

[ymax maxdx]  = max(Protein1_boundary(:,1));

ydiff = ymin - ymax;
if(ydiff >0)  
   Temp_boundary(:,1) = Temp_boundary(:,1) - ydiff;
end

%Leveling X axis

[xmin mindx] = min(Temp_boundary(:,2));

[xmax maxdx]  = max(Protein1_boundary(:,2));

xdiff = xmin - xmax;

Temp_boundary(:,2) = Temp_boundary(:,2) - (-xdiff); 

    end

Where did you upload your images? I need to see your original images and the overlapped results, and an image of how you'd like it to look.
