Collect and plot data and legend depending on folder name

Hello together,

I have multiple data that will be analyzed with TP-Rate and FD-Rate and plot this to ROC curve.

I want to compare data with this principle (german):

(I want to compare datasets from fifferent motors with two microphones and two distances, and three measure scenario)

My folder Strukture is here:

At the moment I get this graph:

I want to have graphs like this:

or this

So, I want to collect a foldername from Motor_Set_x to 2-3 subfolder and print it in legend to compare data from first and second folder.

Here is my code:

for loop with k calculations
end

labels = (1:k);
figure('Name',' receiver operating characteristic','NumberTitle','on');
hold on
p11 = plot(M(:,2),M(:,1),'ro','Color','g'); %Here I can randomize a colors
buffer = [.1 .3 .5];
buffer = repmat(buffer,1,ceil(numel(M(:,2))/numel(buffer))); 
buffer(numel(M(:,2))+1:end) = []; 
[~, ySortIdx] = sort(M(:,2)); 
buffer(ySortIdx) = buffer; 
labelpoints(M(:,2),M(:,1), name_save, 'E', buffer)
hold on
help_x = 0:0.1:1;
help_y = 0:0.1:1;
plot(help_x,help_y,'--');
xlabel('False discovery rate')
ylabel('True positive rate')
xlim([0 1]);
ylim([0 1]);
lgd = legend([p11],'Result','Location','east');
title(lgd,'n = Measure number')
tube_size_help = sprintf('%.0f',tube_size);
nameX=strcat(name ,'_tube_size_',tube_size_help);
saveas(gcf, 'result_F0_detection_1M.png')
save 'result.mat' M

Do you have some idea? Thank you!

While for loop I use a variable FilePath that looks everytime like this:

/home/user/workspace/QT/Software_2.0_QT/IO/Motor_Set_1/AKG_C1000S/Distance_0.5m/Scenario_M2/004_m1_m4_60_const_20200611_200711/

maybe it an be useful to extract foldernames?
