Why are EPS files generated by gnuplot rotated 90 degrees?

Question

I have an EPS file generated by gnuplot. I used the code:

#set term post enh color
#set out '1.eps'

The EPS file viewer in gsview is horizontal. However, when I include it in my paper the graph is rotated 90 degrees (vertical)

I tried set term post enh color port, it doesn't work.

However, I found the following code can be used with LaTeX:

#set term post enh color eps
#set out '1.ps'

then use gsview to convert the PS file to EPS. It will be displayed horizontally in LaTeX (but rotated 90 degrees in gsview)

How can I get the EPS file such that it is rotated 90 degrees in both?

Answer 1

Your first line set term post enh color says you want a PS file, while the second line, set out '1.eps' - that you want an EPS file. Gnuplot uses different aspect ratios for PS and EPS output.

Use this:

set term post enh color eps
set ou "1.eps"

Here is the result of this Gnuplot file

set term post enh color eps
set ou "1.eps"
plot x
set ou

and TeX file

\documentclass{article}
\pagestyle{empty}
\usepackage{graphicx}
\begin{document}
\includegraphics{1}
\end{document}
