How to deal with legend for multiple curves in one figure?

I have a multiple curevs in one figure and I wanna add a legend to each curve.

So, instead of data1, data2, data3, data4, and data5, I want to replace them with

phi = 0 & psi = 0

phi = psi

phi = [0,5,10,15,20,25,30] & psi = 0

phi = 0 & psi = [0,5,10,15,20,25,30]

phi = [0,5,10,15,20,25,30] & psi = [0,5,10,15,20,25,30]

I tried many times, but I could not reach to solution. May I get an assistance please?

One way is to set the DisplayName of each line when you plot it:

names = {
    'phi = 0 & psi = 0'
    'phi = psi'
    'phi = [0,5,10,15,20,25,30] & psi = 0'
    'phi = 0 & psi = [0,5,10,15,20,25,30]'
    'phi = [0,5,10,15,20,25,30] & psi = [0,5,10,15,20,25,30]'
    };

hold on % do "hold on" before you plot
for ii = 1:5
    plot(rand(1,10),rand(1,10),'DisplayName',names{ii}); % (plotting random data because I don't have your data)
end

xlabel('X (m)');
ylabel('Received power (dBm)');
legend();
