bodegraph package just display grids but not curves

Question

I'm using pdfLatex (with --shell-escape option) and I had a problem of compilation with TexWorks that was successfully solved with the help of other post in this site: bodegraph on Ubuntu 10.04.

After correcting that error the code compiles smoothly but just displays the logarithmic grids, not the function. The gnuplot files are created in the right place, but the graphic doesn't come out in the PDF.

Code from Martin Scharrer’s asnwer:

\documentclass{article}

\usepackage{tikz}
\usepackage{bodegraph}

\begin{document}

\begin{tikzpicture}[
    gnuplot def/.append style={prefix={}}, % Fixed the issue (prefix was 'gnuplot/\jobname/' before)
]
\begin{scope}
\UnitedB
\semilog{-1}{2}{-50}{60}

\BodeAmp{-1:1.35}{\POAmpAsymp{4}{2.0}+\IntAmp{1}}

\end{scope}
\end{tikzpicture}
\end{document}

Any clues?

Answer 1

Example compiles on my distribution (miktex2.9, gnuplot and windows 7 and texworks as editor). I compile with pdflatex - enable-write18

But, you have to choose xscale and yscale (default unit is cm)

for x you have to draw 3 decades, if the desired width is 10cm then xscale=10/3 the same thing for yscale, here you can choose yscale=10/110 (110dB)

\documentclass{article}

\usepackage{tikz}
\usepackage{bodegraph}

\begin{document}

\begin{tikzpicture}[
    gnuplot def/.append style={prefix={}}, % Fixed the issue (prefix was 'gnuplot/\jobname/' before)
]
\begin{scope}[xscale=10/3,yscale=10/110]
\UnitedB
\semilog{-1}{2}{-50}{60}

\BodeAmp{-1:1.35}{\POAmpAsymp{4}{2.0}+\IntAmp{1}}

\end{scope}
\end{tikzpicture}
\end{document}

thancks

Answer 2

For me the answer was to use -shell-escape or -enable-write18. If I understood correctly, this allows PdfLaTeX to run commands on the terminal (in this case to run gnuplot). Since commands could be harmful, this option is disabled by default.

To activate it, make sure to pass the option before %.tex (pretty obvious but took me a while)!

Finally, my TexStudio configuration on ArchLinux with gnuplot installed looks like this:

Answer 3

Your figure seems to be a bit unfortunate, so I give an answer to this answer. I could make it work on MacOS by

1. First create a folder gnuplot,

   mkdir gnuplot

2. Then create a subdirectory with the same name as the filename except for the .tex extension. So if the file has the name test.tex, I'd say

   mkdir gnuplot/test

3. Then compile the file with

   pdflatex -enable-write18 test.tex
