how i can plot orbit of vibration of a rotating shaft with its center

clear all
close all
x1=BD(1:10000,1 )       % the vibration vector readings in x direction 
y1=BD(10000:15000,2)    % the vibration vector  readings in y  direction 
figure
p1= plot(x1,y1)
xlabel(' journal Disp in X direction');
ylabel('journal Disp in  Y direction');

[KSSV]

x1=BD(1:10000,1 )       % the vibration vector readings in x direction 
y1=BD(10001:20000,2)    % the vibration vector  readings in y  direction 
figure
p1= plot(x1,y1)
xlabel(' journal Disp in X direction');
ylabel('journal Disp in  Y direction');

OR

x1=BD(1:10000,1 )       % the vibration vector readings in x direction 
y1=BD(1:10000,2)    % the vibration vector  readings in y  direction 
figure
p1= plot(x1,y1)
xlabel(' journal Disp in X direction');
ylabel('journal Disp in  Y direction');
