why is the figure dioriented?

Hi im trying to plot the imaginary and real parts of the array, but the figure seems dioriented.

here is the code:

clear all
clc
% known values:
r1=5; r2=1; r3=5; r4=7; AP=5; s=0.873;
thata2=0:0.0314:6.283185;


for i=1:length(thata2) 
    
    z(i)=r1-(r2*exp((thata2(i))*1i));
    %find thata 3:
    a(i)=(conj(z(i))).*r4;
    b(i)=(z(i)).*conj(z(i))+(r4)^2 -(r3)^2;
    c(i)=(z(i)).*r4;
    T3(i)=(-b(i)+sqrt((b(i)).^2-(4.*(a(i)).*(c(i)))))/(2.*(a(i)));
    T3n(i)=(-b(i)-sqrt((b(i)).^2-(4.*(a(i)).*(c(i)))))/(2.*(a(i)));
    angle3(i)=angle(T3(i));
    
    %%find thata 4:
    T4(i)=(z(i)+(r4.*T3(i)))/r3;
    T4n(i)=(z(i)+(r4.*T3n(i)))/r3;
    angle4(i)=angle(T4(i));
    
    
    
    %find position analysis for point AP:
    A(i)=angle3(i)-s;
    RA(i)=r2.*exp((thata2(i))*1i);
    RAP(i)=(r2.*exp((thata2(i)).*1i))+(AP.*exp(((A(i))).*1i));
    
    
    
end 


figure
plot(real(RA),imag(RA))
hold on
plot(real(RAP),imag(RAP));
hold off
title('paths of points A and P')
xlabel('real part')
ylabel('imaginary part')

figure
plot(thata2,angle3)
hold on
plot(thata2,angle4)
hold off
title('thata 3 and thata 4 Vs thata 2')
xlabel('thata 2')
ylabel('thata 3 & thata 4')
grid on 
legend('thata3','thata 4')

"but the figure seems dioriented."

What does disoriented mean in this context?
