I have actual x and y data for a length of 8193, i.e Z=[(X1,Y1) (X2,Y2)....(X8193,Y8193)] . I want to plot (xn,yn) for n size of data pairs with repeating the y value after each 8193 interval while the x continuously increment with one for each data. thanks

sir, I have tried with small size number (to repeat after multiple of 9 for 100 data sets. But still I have not get it. 1. how each x(i)and y(i) value gets its value. I expect a triangular shape with touching x at 1 9 18 29 etc thanks

y=[1 2 3 4 5 4 3 2 1]
 x=[1 2 3 4 5 6 7 8 9]
 xn=ones(1,100);
 j = 1;
for i = 1:length(xn)
  if(j==10)
    j = 1;
  end 
    if i<=5
       y(i)=i;
    else 
      y(i)=y(5)-y(i-5);
    end
     j = j+1;
   plot(x(i), y(j));
end
