When trying to run the example code below found at How to draw a square wave?, I get the error: "LaTeX Error: File `gnuplot3-gnuplottex-fig1' not found", although I am seeing the eps file created in my folder.
I followed the steps found here to include the --shell-escape in the PDFLaTeX option in WinEdt. I still have the error. I am however able to run other simple gnuplot code like that found here.
Can you tell me why I am getting this error although the eps file is created? Thanks.
Here is the original code:
% Code compiled with pdflatex engine via frozen texlive 2012 on Linux
% Need "-shell-escape" enabled and gnuplot 4.4
\documentclass[preview=true,12pt]{standalone}
\usepackage{gnuplottex} % http://www.ctan.org/pkg/gnuplottex
