Matlab plot to ignore underscores?-CodePudding

I have lots of file names that are labelled in the form:

test1_cvariable1_cvariable2_rvariable.csv

To load and process them all automatically I'm using the code:

%filename
txt = ['test1_cvariable1_cvariable2_rvariable.csv']

%step 1
RNG = [23 0 1539 8];
M = csvread(txt,23,0,RNG);

I'd like to then plot a graph with the corresponding title, but owing to how matlab interprets underscores "_" if I use:

    %plot time vs variable
plot(M(:,1),M(:,8))
xlabel('Time (s)')
ylabel('Var')
title(['Var ' txt])

Gives a title in the form

test1cvariable1cvariable2rvariable

with the c,c & r as subscripts (apologies idk how to do this here, ironically)

How do I get Matlab to not make the character immediately after the underscore as a subscript?

CodePudding user response：

You can set the Interpreter property to ‘none’ to disable MATLAB’s usual default which is ‘TeX’. This works for most plotting text functions like title, xlabel, or ylabel.

For example:

title('savvy_iguana', 'Interpreter', 'none')

CodePudding user response：

You have to replace _ with \_ (see this mathworks answer). You can do it automatically using strrep:

title(['Var ' strrep(txt,'_','\_')]
