Avoid lower case in legend by plotting legend with 'DisplayName'

Hello,
I have again a similar Problem, but in this case I can't separate legend, and : 'Interpreter','none' is here also not working. How can I print names like 001_M1_Distance_0.5m_AKG_C1000S_F1_MS1 without undercases?
label1 = extractBefore({i(j).name}, ".mat");
label1 = extractAfter(label1, "_");
...........
if any(M1)
plot(M1(:,2),M1(:,1),'-o','DisplayName',label1{1});
hold on
end
if any(M2)
plot(M2(:,2),M2(:,1),'-o','DisplayName',label2{1});
hold on
end
if any(M3)
plot(M3(:,2),M3(:,1),'-o','DisplayName',label3{1});
hold on
end
if any(M4)
plot(M4(:,2),M4(:,1),'-o','DisplayName',label4{1});
hold on
end
Thanks!

Use the 'Interpreter', 'none' option in legend():
% Read headers
plot(1:10);
hold on
plot(4:14);
legend('plot_1', 'plot_2', 'Interpreter', 'none', 'Location', 'Northwest');

I'd use counter instead of cnt - it's more descriptive it sounds a lot less naughty, than "I know, one cnt is enough".
You might want to consider contains(string, pattern, 'IgnoreCase', true) instead of strcmp(). Or at least use strcmpi() for more robustness. And you might want to cast to lower because you're never totally sure if the extension returned by the operating system will be upper case or lower case:
extractBefore(lower({i(j).name}), '.mat');
When you're assigning the M's you don't need parentheses:
M4 = R4 / cnt4;
Personally I like spaces around operators but that's a matter of style.
You should also have an else clause with no if. What if none of the criteria are satisfied? Will your code will work, or will you get an error downstream because nothing got assigned?

Use labels without _ .
regexprep('001_M1_Distance_0.5m_AKG_C1000S_F1_MS1','_','') % to remove underscores

Sorry I was scribing in description wrong - I want keep '_' this, but I dont want to have a letters undercase!
