Hello,
I'm trying to make my color bar have a title, and I want to give it a math equation. Here is my code.
cbh = findall(fh, 'Type', 'ColorBar');
cTH = get(cbh,'Title');
set(cTH,'String',['$',var,'(r)/','\underset{\text{LEV}}{\text{mean}}(',var,')$'])
The variable var is just a string in my code, you can make it any letter.
After getting to the third line in my code I get this error, and $var(r)/\underset{\text{LEV}}{\text{mean}}(var)$ showed up as the title for my colorbar.
Warning: Error updating ColorBar.
String scalar or character vector must have valid interpreter syntax:
However, if I open a live script in Matlab and type the content of the LaTeX script and run it successfully gives the equation.
I thought maybe the interpreter was something other than LaTex, so I tried changing it with the methods below but nothing happened. But I did go and check and they were already set as latex.
cbh.Title.Interpreter = 'latex';
cTH.Interpreter = 'latex';
So why am I getting this error? I checked in other LaTeX packages, and the syntax is correct. I also looked into the MatLab documentation and it seems like I am doing everything correct.
