Best Answer

Try this — 
figure
h = animatedline('linewidth',2);
axis([1 7 1 7])
axis ij
grid on
x=1:4;
n = 100;
xx=linspace(x(1),x(end),n);
y = [1 1 2 1];
yy = interp1(x,y,xx);
for ci=1:n
        addpoints(h,xx(ci),yy(ci));
        pause(0.03);
        drawnow
        if yy(ci) == max(y)
            text(xx(ci), yy(ci), '$\uparrow Maximum$', 'Horiz','left', 'Vert','top', 'Interpreter','latex')
        end
        if ci == n
            text(xx(ci), yy(ci), '$\leftarrow End$', 'Horiz','left', 'Vert','middle', 'Interpreter','latex')
        end
end
