How can i specify which subplot that i want to plot on it?

Hi everyone! Now, i want to draw an animated arrow (general is any object) and an animated line, each of them is plotted on each subplot. I used draw-delete method to create an animated arrow and use "addpoints" command to create an animated line. Of course, we need a for loop, and so on. You can see below code. But, i couldn't do what i want with this code. The animated arrow always drew on second subplot. Who can help me? P/s: My problem is "How can i specify which subplot that i want to plot on it?" Thank you so much. And, my code:

clear
clc
subplot(2,1,1);
axis([-1 24 -1.1 1.1]);
line([0 23],[0 0],'Color','r');
jumpstep=0.1;
subplot(2,1,2);
axis([0 240 -1.1 1.1]);
sodiem=linspace(0,23,231);
cvi=sin(sodiem);
higharrow=0.8;
ani=animatedline('Color','y');
for k=0:length(sodiem)-1
    arr=arrow([jumpstep*k higharrow],[jumpstep*k 0],13,'EdgeColor','r','FaceColor','g');
    addpoints(ani,sodiem(k+1),cvi(k+1))
    drawnow
    pause(0.01)
    delete(arr);
end

use axis handles,

ax1 = subplot(2,1,1);
something
ax2 = subplot(2,1,2);
something

now again go back to ax1

axes(ax1)
hold on
something more

You're welcome!

the axes did not work for me. I used this instead

set(gcf,"CurrentAxes",axs(ax1));

@Costas, not sure what axs is.

Anyway, to specify what axes to draw into you can simply call subplot again. You aren't limited to calling it just once and then storing the axes handle and messing around with that - too confusing. Simply call subplot again with the axes you want specified as the third argument:

% Switch current axes to subplot 1:
subplot(2,1,1);
% Now draw something in subplot 1.
hold on;
plot(rand(1,10));

% Switch current axes to subplot 2:
subplot(2,1,2);
% Now draw something in subplot 2.
hold on;
plot(rand(1,10));
