In the picture numbers are mentioned.....1 to 12....so do you have those coordinates in hand? If so use plot(x,y,'color') for each set of coordinates and use hold on....

Dear Siva: I did what you said. but I've got a problem. I dont know how to change the color in "for loop".I use plot command in a "for loop".but I can not change the color in plot command.for example in first iteration I want to have red color and in second iteration i wanna have green color.I dont know what to do. thanks in advance

colortable = [0 0 0;      %black
              0 .8 .1;    %bright-ish green-ish
              .05 .5 0.05;     %darker green-ish
              ...         %etc
             ];

for K = 1 : number_of_segments
   these_x = segment_x{K};
   these_y = segment_y{K};
   this_color = colortable(K,:);
   plot(these_x, these_y, 'Color', this_color);
   hold on
end
