Ciao a tutti.Ho sempre utilizzato gnuplot per fare alcuni grafici semplici di dati presi in laboratorio, ma mi sono accorto che inserire un grafico generato da gnuplot stona parecchio. Ho allora trovato su “Gnuplot in action” di P. K. Janert la soluzione: ossia utilizzare il terminale epslatex per separare l’immagine .eps dal testo, che viene poi successivamente compilato con LaTeX. Si può quindi utilizzare il modo matematico di LaTeX per scrivere titolo, funzioni, …
Comodo ma… non mi funziona.
Ottengo l’errore seguente:
`[3] (/usr/local/texlive/2011/texmf-dist/tex/latex/base/ts1cmr.fd)
?
`Il mio preambolo è il seguente:
`\documentclass[a4paper,twocolumn]{article}\usepackage[utf8]{inputenc}
\usepackage[francais]{babel}\usepackage{graphicx}
\usepackage{booktabs}\usepackage{mathtools}
\usepackage{amsmath}
\usepackage{amsfonts}
\usepackage{amssymb}
\usepackage[version=3]{mhchem}
\usepackage[output-decimal-marker={.},separate-uncertainty=true]{siunitx}
\usepackage{graphicx}\DeclarePairedDelimiter{\abs}{\lvert}{\rvert}`
Mentre per inserire il grafico utilizzo il seguente codice:
`\begin{figure}
\centering
%\includegraphics[width=0.9\columnwidth]{Graphiques/HC3COOH-T1.pdf}
\input{Graphiques/HC3COOH-T1}
\caption{Titrage de\ce{CH3COOH} (1)}{Titrage d'une solution aqueuse de \ce{CH3COOH} par une solution aqueuse de \ce{NaOH} $\sim \SI{0.1}{\mole.\liter^{-1}}$: première épreuve.} \label{G3}
\end{figure}`Infine, allego pure il file HC3COOH-T1.tex prorotto automaticamente da gnuplot, perché l’errore é contenuto in esso:
