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

Hi @Bas Bloemendaal,

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:
