Labeling multiple plots along the plotted line on the same figure

I have a program to check how power vs wind speed curve changes when the Gear Ratio changes. I have 6 Gear Ratios 21.58 and 22 through 24 at steps on 0.5. I want to the each plotted curve within the loop such that along the plotted curve it should read "GR=21.58" for the 1st gear ratio. My code is as below:

%Program to create a Power vs Wind Speed Curve for a Fixed Speed Wind
%Turbine of 100kW
clear all
close all
clc
%WIND TURBINE SYSTEM PARAMETERS
D = 18.5;    %Rotor diameter in m
GR= [21.58,22:0.5:24];   %Gear Ratio of the gearbox connecting rotor to generator
beta= 2.2;   % Angle of attack for maximum efficiency of the turbine
%AIR PROPERTIES
rho = 1.27;    % Density of air kg/m^3
Vw = [0.001:0.01:25]; %Vector of Wind Speed Incident on the turbine
% GENERATOR SYSTEM PROPERTIES
Wgen = 1800;   %Synchronous Speed of the Generator in rpm
%CALCULATING TIP SPEED RATIO
%Calculating Tip Speed
for i=1:6;
    Vt= ((Wgen.*pi/30)./GR(i)).*(D/2);
    Lambda =  Vt./Vw;
    %Heier Approach to Calculate the Coefficient of Performance (Cp)
    %Matrix of Coefficient
    C=[0.5 116 0.4 0 0 6 21 0.08 0.035];
    Lambda_i = ((1./(Lambda+(C(8).*beta)))-(C(9)./((beta.*beta.*beta)+1))).^(-1);
    Cp=0.5*((C(2)./Lambda_i)-(C(3).*beta)-C(6)).*exp(-C(7)./Lambda_i);
    %Calculation of Power
    P=0.5*rho*((pi/4)*(D*D/2).*(Vw.^3)).*(Cp./1000);
    %Finding the rated Power
       plot(Vw,P,'LineWidth',3);
       grid on
       hold on
end
xlabel('Wind Speed [m/s]');
ylabel('Power [kW]');

Add Legend: Add this line at last of the code

legend({'GR:21.58','GR=22','name1','name2','name3','name4'},'Location','northwest')
