Rectangle wave in MATLAB App Designer

I'm using App designer for plotting rectangular graph for the points inputed by the user. For EX- if user give values for Yaxis as 1 , 2 ,4 , 5 and 2, 4, 1 , 3 for the Xaxis corresponding to the values of Yaxis. From this given data how can i plot rectangular graph for this given 4 points in MATLAB App Designer.

Please Help.

First convert the given points in the correct order for drawing a polygon

x = [2, 4, 1, 3];
y = [1, 2, 4, 5];

pts = [x(:) y(:)];
idx = boundary(pts);
pts = pts(idx, :);

Then either use plot() or patch()

plot(pts(:,1), pts(:,2))
% or
patch(pts(:,1), pts(:,2), 'r')

This produces a Recatngle shape. i want graph of this type ->

  t = app.EntertheSignalEditField.Value;
  t1 = str2double(strsplit(t));
  x =  1 :numel(t1); 
  
  thats how im going to take values for Y axis from user and print it 
  user will be giving values in this format - 1 2 3 4 (using space not comma)
