Displaying Greek letters with subscripts inside plot

Question

I am using ListPlot:

 ListPlot[dpl[[All, 1, {1, 3}]], Frame -> True,
 FrameLabel -> {SubsuperscriptBox["\[Xi]", "in", ""] // DisplayForm,
 "Inefficiency \[CapitalDelta]"}, 
 Joined -> True,
 PlotLabel -> {SubsuperscriptBox["\[Xi]", "out", ""] // DisplayForm} ~~
 ToString[dpl[[1, 2, 2]]]]

However this gives me a poor y-label: '$\{\xi_{out}\} \~\~ 7$'. How do I get this code to display '$\xi_{out}=7$'?

I don't understand the question. Please show a self-contained example, explain what you expect and how that differs from what you get. The PlotLabel -> { ... // DisplayForm} ~~ ToString[...] part of the code doesn't seem to make sense, and it's not clear to me what you are trying to achieve with ~~, which is an operator for use with string patterns. — Szabolcs, Jun 29 '15 at 15:33
Maybe you are looking for PlotLabel -> (TraditionalForm@HoldForm[Subscript[\[Xi], out] = #] &)[ 7]. — Szabolcs, Jun 29 '15 at 15:36

As well as Szabolcs does I do not understand the question, but what I understand is that you (a) use the BoxLanguage incorrectly and (b) in the place where it is easier not to use it, but to make use of more simple tools. In particular, instead of {SubsuperscriptBox["\[Xi]", "in", ""] // DisplayForm you may type Esc+x+Escthen Ctrl+-and then in. You will get what you need, no difficulties. Or also PlotLabel->Style["y=7"] where y=Esc+x+Escthen Ctrl+-and then out You did not explain what is dpl, hence I cannot help more. — Alexei Boulbitch, Jun 29 '15 at 16:18

I think you are working too hard; i.e, using lower-level forms than you need to. Let Mathematica do the heavy lifting.

plt = Range @ 10;
ListPlot[plt,
  Frame -> True,
  FrameLabel -> {Subscript["ξ", "in"], "Inefficiency Δ"}, 
  Joined -> True,
  PlotLabel -> Row[{Subscript["ξ", "out"], "  ", plt}]]
