Trouble labeling the lines on my MatLab plot

I need to make my graph look like this: here is my code:

close all

clear all

clc

%%defining variables

dt = .001;

numberOfCalculations = 10000;

velocityX(1) = 70 * .44704 %mph to m/s

velocityY(1) = 0;

velocityZ(1) = 0;

positionX(1) = 0;

positionY(1) = 3.5*.3048;

positionZ(1) = 0;

Bm = 1;

g = 9.81;

Som = 4.1 * 10^(-4);

w = 30*2*3.14; %rad/s

mass = 149/1000;

So = Som * mass;

delta = 5;

vd = 35;

t=1

K = zeros(4);

L = zeros(4);

M = zeros(4);

N = zeros(4);

P = zeros(4);

Q = zeros(4);

for t = 1:numberOfCalculations

for i = 2:5

velocity = sqrt(velocityX(t)^2 + velocityY(t)^2 + velocityZ(t)^2);

Bm = .0039 + (.0058)/(1+exp((velocity-vd)/delta));

% K(i) = h * velocityX(i);

K(i) = dt * (velocityX(t) + (L(i-1)/2));

%L(i) = h(-Bm)*sqrt( velocityX(i)^2 + velocityY(i)^2 + velocityZ(i)^2) * velocityX(i);

L(i) = dt*(-Bm)*sqrt( (velocityX(t) + (L(i-1)/2))^2 + (velocityY(t) + (N(i-1)/2))^2 + (velocityZ(t) + (Q(i-1)/2))^2) * (velocityX(t)+(L(i-1)/2));

%M(i) = h * velocityY(i);

M(i) = dt * (velocityY(t) + (N(i-1)/2));

%N(i) = -h * g;

N(i) = -dt * g;

%P(i) = h * velocityZ(i);

P(i) = dt * (velocityZ(t) + (Q(i-1)/2));

%Q(i) = h * ((-So * w)/(m)) * velocityX(i);

Q(i) = dt * ((-So * w)/(mass)) * (velocityX(t) + (L(i-1)/2));

end

positionX(t+1) = positionX(t) + (1/6) * (K(2) + 2 * K(3) + 2 * K(4) + K(5));

velocityX(t+1) = velocityX(t) + (1/6) * (L(2) + 2 * L(3) + 2 * L(4) + L(5));

positionY(t+1) = positionY(t) + (1/6) * (M(2) + 2 * M(3) + 2 * M(4) + M(5));

velocityY(t+1) = velocityY(t) + (1/6) * (N(2) + 2 * N(3) + 2 * N(4) + N(5));

positionZ(t+1) = positionZ(t) + (1/6) * (P(2) + 2 * P(3) + 2 * P(4) + P(5));

velocityZ(t+1) = velocityZ(t) + (1/6) * (Q(2) + 2 * Q(3) + 2 * Q(4) + Q(5));

if positionX(t) >= 60

break

end

end

positionX = positionX/.3048;

positionY = positionY/.3048;

positionZ = positionZ/.3048;

I tried various numbers for the position and I can't find the right ones. Can you put the arrows in too?
