Confusion Matrix class-label

I want to write the class labels of my confusion matrix as 'f subscript 1', 'f subscript 2' etc. However when I am defining as

cm = confusionchart([20 0 0; 0 20 0; 0 0 20],{'f_1','f_2','f_3'}),,,But the class labels are coming as 'f_1', 'f_2' etc. The subscripts are not coming.

I have also tried this...cm = confusionchart([20 0 0; 0 20 0; 0 0 20],{'$f_1$','$f_2$','$f_3$'}, 'Interpreter','latex' )....This is showing an error message.

Can anybody please help me out?

To put latex in XTickLabel and YTickLabel, you can use the plotconfusion() function. plotconfusion() has a Children Graphics field whose second element is Axes and it can be modified to change the XTickLabel property which supports latex as well.

But, confusionchart() does not return the axes. It returns a ConfusionMatrixChart variable which does have a ClassLabels field but it is read only. There is an option to specify ClassLabels while declaring the confusion matrix, but it does not take latex formatted values.

Hope this helps.
