How could I move my xlabel in the center to the right?

As you can see "Grados" is on the lower left, I would like to move it to the center. I mean in the same line but towards the center, how could it? thank you very much

function arduinomatlab


v1=zeros(1,1000);
v2=zeros(1,1000);
delete(instrfind({'Port'},{'COM3'}));
s = serial('COM3','BaudRate',9600,'Terminator','CR/LF');
warning('off','MATLAB:serial:fscanf:unsuccessfulRead');

fopen(s);

muestras=1;

figure('Name','Captura');
xlh = xlabel ( 'Grados' );
xlh.Position (2) = xlh.Position (2) - 1.1;
ylim([-1 1]);
xlim([0 369]);
ax = gca;
ax.XAxisLocation = 'origin'; 
ylabel('Y')
title('Onda Sinouidal')

grid on
hold on


while 1


xticks([30,60,90,120,150,180,210,240,270,300,330,360])

try
valor=fscanf(s, '%f,%f')';
v2(muestras)=(valor(2));
v1(muestras)=(valor(1));
plot(v2(1:muestras),v1(1:muestras),'-k')
drawnow
muestras=muestras+1;
catch
break
end
end   
fclose(s);
delete(s);
clear s;

end

Delete the line where you manually position it:

xlh.Position (2) = xlh.Position (2) - 1.1;

then I think it should remain at its automatically-determined location (i.e. centered).

No, it is not like that. It is located in the center of the graph to the right. And I wish it was down the graph but centered

[Image Analyst]

It seems to be caused by this line:

ax.XAxisLocation = 'origin';

If you comment that out it will be centered. You can use line() to draw an x axis but the tick labels won't be there:

line(xlim, [0, 0], 'Color', 'k', 'LineWidth', 2);
