MATLAB eps export doesn't include legend box - matlab

Question

I am trying to export figures from MATLAB in publication quality for importing into LaTeX documents.
I am able to set all the graphics properties I would like, however when I export my figure as a .eps, the box around the legend disappears.
MWE below (I'm using MATLAB 2014b):
figure
plot(1:4)
legend('A line!')
print('LineTest','-depsc2','-tiff')
In LaTeX:
\usepackage{graphicx}
\usepackage{epstopdf} %converting to PDF
\begin{document}
\includegraphics[width=\textwidth]{LineTest}
\end{document}
This gives the following result, which has no legend box:

It works fine for me with using Matlab 2016a and your TeX document. The following TeX document also works, try it, maybe it is an issue with your TeX compiler:
\documentclass[a4paper]{article}
\usepackage[pdftex]{graphicx}
\begin{document}
\includegraphics[width=\textwidth]{LineTest.eps}
\end{document}
Running epstopdf manually on the EPS image also gives a PDF with the legend in a box. Can you run it from the command line and see whether the problem is still there for you?

Answer 2

I had a similar issue. I was saving two figures as eps files and using them in Latex. The figures were saved automatically using:
print(filename, '-depsc2', '-tiff')
I was using TexStudio and Miktex 2.9 with the command:
\includegraphics[width=\textwidth]{filename.eps}
The first file did not have the bounding box around the legend but the second file did.
The work around I found was to manually save the figure (Figure → Save As...) as filename.eps. The bounding box then showed up in TexStudio.
