How can I plot multiple results from a function on the same graph?

Hello everyone,
I'm working on a Windchill conversion assignment, any guidance would be highly appreciated.
I want to display each result from the function (windchill_calc) - which takes a pre-defined temperature vector and a user inputted vector (of 5) and works out windchill (W_2)
Except the plot is only showing the result from the 5th value of the vector, I understand why this is happening and that this is quite a simple error but I can't work out a solution - any ideas?
(temp_vector is previously defined)
_______________________
windspeed_user = input('please enter a 5 windspeed vector'); %requesting input from user.
i = 1;
for i = 1:1:5;
W_2 = Windchill_calc(temp_vector, windspeed_user(i)) %calls function
end
plot (W_2, temp_vector)
xlabel ('Temperature (Fahrenheit)')
ylabel ('Windchill results')
grid on

I guess you have to work a bit with your data, but the hold on, hold off is what you need:
windspeed_user = input('please enter a 5 windspeed vector'); %requesting input from user.
i = 1;
for i = 1:5;
W_2 = Windchill_calc(temp_vector, windspeed_user(i)) %calls function
hold on
plot (W_2, temp_vector)
end
hold off
xlabel ('Temperature (Fahrenheit)')
ylabel ('Windchill results')
grid on

Each iteration of the loop, you are over-writing all of W_2, so at the end of the loop only the final assignment has had any effect.
It appears to me that your W_2 would be a vector. If so, then
for i = 1 : 5
W_2 = Windchill_calc(temp_vector, windspeed_user(i)) %calls function
plot(temp_vector, W_2);
hold on
end

Notice I also switched W_2 and temp_vector, as the independent variable should go first in the plot()
