I am plotting a function and for labeling the axes I use:

AxesLabel -> {Style[y, FontSize -> 21], Style[{Subscript[f, i], Subscript[q, i]}, FontSize -> 21]}

here $y$ is for the $x$-axis and $\{f_i,q_i\}$ is for the $y$-axis. The problem is that I dont want to have $\{\}$. I only want to have $f_i,q_i$ at the $y$-axis. How can I manage this?

Thank you very much.

    $\begingroup$ Just use a string for the Y label: Style["\!\(\*SubscriptBox[\(f\), \(6\)]\),\!\(\*SubscriptBox[\(q\), \ \(6\)]\)", FontSize -> 21] (use ctrl-_ to enter the subscript in the string, then just Style the string to desired font size) $\endgroup$

Use a string for the Y-axis label, e.g.:

AxesLabel -> 
 {Style[y, FontSize -> 21], 
  Style["\!\(\*SubscriptBox[\(f\), \(6\)]\),\!\(\*SubscriptBox[\(q\), \ \(6\)]\)", 
    FontSize -> 21]}

You can use the key combination of Ctrl+_ to enter subscripts directly into the string, then use Style on the string to alter font size, etc.

Here's a (mostly) non-string approach, using Row to string expressions together:

 AxesLabel -> {Style[y, FontSize -> 21], 
               Style[Row[{Subscript[f, i], Subscript[q, i]}, ","], FontSize -> 21]}]

You can also use StringForm:

Plot[x, {x, 0, 1}, AxesLabel ->
    (Style[#, 21] & /@ {y, StringForm["`1`,`2`", Subscript[f, 6], Subscript[q, 5]]})]
