i am doing my project on hand written word image, and am plotting points on the image using CXX and CYY matrix in my program, after pointing i want to connect those point i do not know how to connect those points and form graph image.

clc;
clear all;
close all;
X=imread('i2.jpg');
imfinfo('i2.jpg')
figure,imshow(X)
b = imresize(X,[100,100]);
si = size(b,1);
sj = size(b,2);
figure;imshow(b);
% Binarization
th = graythresh(b);
I = im2bw(b,th);
w = 5;
h = 5;
c=si/w;
r=sj/h;
kl=bwmorph(~I,'thin',inf);
figure,imshow(kl)
R(:,:)=kl(:,:);
I=1;
U1=w;
J=1;
U2=h;
E=1;
for i=1:r
  for j=1:c
B(I:U1,J:U2)=R(I:U1,J:U2);
[x,y]=find(B==1);
CX=mean(x);
CY=mean(y);
CXX(E)=CX;
CYY(E)=CY;
T(I:U1,J:U2)=B(I:U1,J:U2);
J=J+w;
U2=U2+h;
E=E+1;
clear B x y
 %CYY(isnan(CYY)) = [];
 %CXX(isnan(CXX)) = [];
  end
I=I+w;
U1=U1+h;
J=1;
U2=h;
end
%kl(isnan(kl(:,1)),:) = [];
imshow(R)
hold on
hold on
plot(CYY,CXX,'.c','Markersize',8)
hold off
 r = imread('empty.jpg'); %Reading empty white blank image for plotting purpose
 re = imresize(r,[100,100]);
 figure,imshow(re)
% hold on
 hold on
 plot(CYY,CXX,'.k','Markersize',20);
 hold off
