Hi guys, im trying to add a text arrow to a graph. It is a projectile motion curve so has a maximum point. This point is calculated using formulas and the variables given by the user. The coordinates of the maximum point in my code is (Sx_max, S_y). How do I plot a textarrow pointing to this with a label of the time taken num2str(T_up). Ive only been able to find examples with excat points, but my situation has a point that changes according to the values entered.
Thanks for the help

Read about quiver
n = 10 ;
x = 1:n ;
y = rand(1,n) ;
[val,idx] = max(y) ;
figure
hold on
plot(x,y)
quiver(idx,val,0,1)
