MATLAB: Convert variable to a title – includes special charcters

MATLABprint titlevariable to string

I am storing a file name as a variable to be retrieved. But, the name of the file contains underscores. When I use the variable name as the title of my plot each letter that follows an underscore becomes subscripted. What I would like is for the underscores to remain underscores. Example: FileName=SD_Padres_are_great;

Then I plot a chart & I use this as the title: title(FileName);

In the above example the output title would print with the underscores missing and the P a & g subscripted.

Does anyone know how to keep the title in the exact format of the FileName? BTW-I do not have control of the file names to change them as they are created by another program.

Best Answer

You could use the command "strrep" to replace the underscores with spaces:

strrep(FileName,'_',' ')

or if you want to keep the filename exact with the underscores, insert a backslash:

strrep(FileName,'_','\_')

which will print the underscore as an underscore instead of treating it as a indicator for subscripting.

MATLAB: How to print path in figure title? It’s screwing up the TeX markup

You have to replace the single backslant ‘\’ in the path name with double backslants ‘\\’ to make that work with TeX. They will print as single backslants though, so it will look as it should. The easiest way to do that is with the strrep function:

path = 'C:\Documents\MATLAB\DragonFiles';
PathName = strrep(path, '\', '\\');

You don’t have to change anything else, and it only changes the string you pass to your title call, leaving the actual path string unchanged. It worked when I tried it on a figure I created to test it, so you should have no problems with PathName created here.

MATLAB: How to turn off the LaTeX interpreter in the legend within MATLAB

The LaTeX interpreter can be turned off for a text object by setting the 'Interpreter' property to 'none'. You can specify the interpreter to be used with the legend using the 'Interpreter' parameter/value pair input argument to the LEGEND function. For example,

figure; plot(1:10)
l = legend({'test_line'}, 'Interpreter', 'none');

Note that the legend string(s) must be enclosed in a cell array.

You can also set the 'Interpreter' property after the creation of the legend:

figure; plot(1:10)
l = legend('test_line');
set(l, 'Interpreter', 'none')
