Giandomenico

Grazie, ma se non ho capito male, è esattamente quello che fa automaticamente Inkscape.
Questo il mio modo di procedere:
Genero le figure o i grafici (pdf o eps) con Matlab, Autocad, ecc… senza etichette o testo, in Inksape aggiungo le etichette, simboli testo e quant’altro, poi Inkscape salva la parte grafica in .ps e la parte di codice (analoga a quella dell’articolo) in un file .ps_tex

Questo è il .ps_tex della figura incriminata:
`%% Creator: Inkscape 0.48.5, http://www.inkscape.org
%% PDF/EPS/PS + LaTeX output extension by Johan Engelen, 2010
%% Accompanies image file 'fig_5-31.ps' (pdf, eps, ps)
%%
%% To include the image in your LaTeX document, write
%% \input{.pdf_tex}
%% instead of
%% \includegraphics{.pdf}
%% To scale the image, write
%% \def\svgwidth{}
%% \input{.pdf_tex}
%% instead of
%% \includegraphics[width=]{.pdf}
%%
%% Images with a different path to the parent latex file can
%% be accessed with the `import' package (which may need to be
%% installed) using
%% \usepackage{import}
%% in the preamble, and then including the image with
%% \import{}{.pdf_tex}
%% Alternatively, one can specify
%% \graphicspath{{/}}
%%

Perfetto ora mi è chiaro 😀 , il problema è che intuitivamente ho sempre cercato di inserire il codice delle figure alla fine dei capoversi, sbagliando 😳
