Looping through array to assign values to titles

Hello,
I want to create a plot that contains a plot of each value of U_det and want each line assigned to each value in the array 'lateral'.
Now I have 5 different plots with the whole array in the legend.
Any ideas how to accomplish this?
Thanks
for i = abs(1:20:size(Bz,1))
Yi = Bz(i,minK(1,1));
lateral_1 = abs(RZ(:,1:49:245));%100.*find_coordinate(R2,Z2,Bz,0,Bi); % 100*: from [m] to [cm]
lateral = fliplr(lateral_1);
M_tot_spions_z = langevinfunc2(n,Kb,T,Brex(i,minK(1,1)), f, Vc, Ms,N);
U_det_r = abs((Yi.*M_tot_spions_z)/100e-9); % Counts 100[nV] Induced voltage [V]
figure;
txt = ['X=', num2str(lateral)];
plot(T_comb,U_det_r, 'DisplayName', txt)
% title([' Detected signal @ depth distance = ', num2str(abs(depth)),' [cm]'])
xlabel('Time [s]')
ylabel('Counts 100[nV]')
hold on
plot(T_comb, Noise)
legend show
end

To plot lines for each value in the‘lateral’array corresponding to each value of‘U_det’, you should execute a loop separately to plot the values of the‘lateral’array within the existing loop. The following modifications may help achieve the desired results:
Initialize the Plot:Place the following lines at the top of your loop to create a single figure and hold the plots:
figure;
hold on;
Replace the Plotting Section:Replace the existing plotting code:
figure;
txt = ['X=', num2str(lateral)];
plot(T_comb, U_det_r, 'DisplayName', txt)
% title([' Detected signal @ depth distance = ', num2str(abs(depth)),' [cm]'])
xlabel('Time [s]')
ylabel('Counts 100[nV]')
hold on
plot(T_comb, Noise)
legend show
With the following code to plot each value of‘lateral’:
for j = 1:length(lateral)
txt = ['X=', num2str(lateral(j))];
plot(T_comb, U_det_r(j,:), 'DisplayName', txt)
end
plot(T_comb, Noise, 'DisplayName', 'Noise')
Finalize the Plot:After the loop ends, add the following lines to label the axes and display the legend:
xlabel('Time [s]')
ylabel('Counts 100[nV]')
legend show
By making these modifications, you will achieve the desired results. Below is an image showing the output using some dummy data:
