# How to add a panel with definition about plots, accompanied by dot and dot-dash lines?

u = 2/(1 + Z1) Sech[T/Z1 + 1/(9 Z1) Log[1 + Z1]]^2;
w = 2/(1 + Z2) Sech[T/Z2 + 1/(9 Z2) Log[1 + Z2]]^2;
Z1 = 5;
Z2 = 10;

Plot[{u, w}, {T, -15, 15}, PlotRange -> {0, 0.45}, Frame -> True,
Axes -> {False, False},
Epilog -> {Inset[
Graphics[{DotDashed, Line[{{0, 0}, {0.19, 0}}]}], {10, 0.41}],
Inset["z=0.1", {13, 0.41}],
Inset[Graphics[{Dashed, Line[{{0, 0}, {0.19, 0}}]}], {10, 0.38}],
Inset["z=0.2", {13, 0.38}]}, PlotStyle -> {DotDashed, Dashed}]


When I want is to change the format of the plot into EPS, though some parts of the plot programed by using Epilog and Inset ( I mean "_._. Z=0.1" and "_ _ _Z=0.2") change their forms and make the plot unreadable! How can I revise my program? I think I should use Panel but I dont know how!

This question came from our site for professional and enthusiast programmers.

ImportString[ExportString[p, "EPS"], "EPS"] (where p is the plot) works mostly fine for me on win7 mma8. Can you specify preciser what the problem is? – Ajasja Jun 6 '12 at 10:44
The result I get using Export["g.eps", g] looks fine. How do you export and what do you get as output? What version of Mathematica do you have? – Szabolcs Jun 6 '12 at 12:50

As noted in the comments, the results from eps export look fine. However, you can use an alternative version of your Epilog with a single Inset working with scaled coordinates as follows:

Epilog ->
Inset[
Grid[{{Graphics[{DotDashed, Line[{{0, 0}, {1, 0}}]},
AspectRatio -> .1, ImageSize -> 30], Style["z=0.1", 12]},
{Graphics[{Dashed, Line[{{0, 0}, {1, 0}}]},
AspectRatio -> .1, ImageSize -> 30], Style["z=0.2", 12]}}],
Offset[{-10, -10}, Scaled[{1, 1}]], {Right, Top}]


(Check for details Inset > Applications > first example in the docs on the content and placement of insets.)

Or, you can wrap the Grid with Panel:

Epilog ->  Inset[Panel@Grid[...]]


If you replace the Epilog->... part of your code with these versions, you get
