How can I write different subscription font type of label?

Like figure below, I want to write phi and CH4 for diffrent font type.

(phi should be Italic but CH4 should not. & CH4 must be a subscription of phi)

How can i do this?

You can achieve that by using a underscore _, following what you'd want subscripted. You can group something by placing it within curly brackets.

In this case:

xlabel('\phi_{CH_4}')

If you want a longer subscript, you should place that subscript also within curly brackets:

xlabel('\phi_{D_{solid}}')

I mean different font type. Sorry for confusing

I've editted my answer and included screenshots. Lowercase \phi is italic.

Hi,

interestingly, subscripting does not work in combination with the boxplot function.

Any help appreciated.

A=rand(100,1)

boxplot(A)

set(gca, 'XTickLabel', {'test_{hey}'})

[Patrick Laux]

ah okay, I found it:

you have to specifiy latex interpreter

set(gca,'TickLabelInterpreter', 'tex');
