Hello, I am trying to get the X and Y values from a Plot. This plot is generated from a loop, and the plot represents the boundary of an image..

close all
clear all
% The image I am trying to read 
A = imread('Britain.png'); 

% The boundaries around the image 
BW = im2bw(A);
[B,L] = bwboundaries(BW);

% To put the x and y values 
double x1=[];
double y1=[];

%imshow(label2rgb(L, @jet, [.5 .5 .5]))
hold on 

% A loop to plot only the boundaries, because I only want the boundary and not the image  
for k = 1:length(B)
   
   boundary = B{k};
   
   plot(boundary(:,2), boundary(:,1), 'r', 'LineWidth', 1)     
   j=findobj(gca,'Type','line')
   x1(k)=j(k).XData(k) 
   y1(k)=j(k).YData(k)

 
end

%plot(x1,y1)

Thank you so much Kevin :)
