I have the following code which generates a mobile plot for the Earth and Mercury during a year:

for k=1:length(t)
    %clear figure
    clf
    %get data
    t_k=t(k);
    x_tm=xt(k);
    y_tm=yt(k);
    x_mm=xm(k);
    y_mm=ym(k);
    %Plot movement
    p=plot(x_tm,y_tm,'co',x_mm,y_mm,'ko',x_mm*0,y_mm*0,'yo','Linewidth',8);
    hold on
    %plot outline of movement
    plot(xt,yt,'b',xm,ym,'r','Linewidth',1);
    hold on
    %plot lines between objects
    lx=[0 0 x_tm; x_tm x_mm x_mm];
    ly=[0 0 y_tm; y_tm y_mm y_mm];
    l=plot(lx,ly,'m','Linewidth',1);
    
    %Details
    grid on 
    xlabel('Distancia en Millones de Kms')
    ylabel('Distancia en Millones de Kms')
    title(['Posición de los planetas al día ',num2str(t_k)]);
    drawnow limitrate
end
