How to include subscript in the variable name in Biplot

Hallo:

I am doing Principal component analysis and I need to add subscripts in my variable name while plotting Biplot.Below is the code I am using:

figure
biplot(coefs(:,1:2),'VarLabels',...
    {'X_{1}' 'X_{2}' 'X_{3}' 'X_{4}''X_{5}' 'X_{6}' 'X_{7}' 'X_{8}''X_{9}' 'X_{10}' 'X_{11}' 'X_{12}'})

But names do not appear in the biplot. But interestingly, I tested with 6 variables instead of 12 and my code worked.

Please help

Hi Khandker,

The issue you're facing with variable names not appearing in the biplot when using 12 variables could be due to a syntax error or plot size constraints.

Here's the corrected version of your code with proper syntax:

figure;
biplot(coefs(:,1:2), 'VarLabels', ...
    {'X_{1}', 'X_{2}', 'X_{3}', 'X_{4}', 'X_{5}', 'X_{6}', ...
     'X_{7}', 'X_{8}', 'X_{9}', 'X_{10}', 'X_{11}', 'X_{12}'});

Hope this helps.
