PgfPlots ybar and ybar stacked conflict

Question

I have one document with 2 documents included. In the first document I have a pgfPlot with \pgfplotsset{ ybar stacked, ...etc } and in the second one \pgfplotsset{ ybar, ..etc }, but the first pgfplotsset goes in conflict with the second, and also the second document has "ybar stacked" option active.

Here the documents:

Main:

 \begin{document}

\include{chapter1}
\include{chapter2}

\end{document}

chapter1

    \pgfplotsset{
ybar stacked, 
enlargelimits =0.05,
legend style ={at={(0.5,-0.5)},
anchor=north,
legend columns=-1},
ylabel={Ore},
xtick=data,
x tick label style={rotate=45,anchor=east},
symbolic x coords={Enrico Rotundo,Federico Poli,Giacomo Fornari,Gianluca Donato,Luca De Franceschi,Nicolò Tresoldi,Serena Girardi}
}

\begin{figure}[H]
\begin{tikzpicture}
\begin{axis}
\input{columnChart_rr}
\legend{amministratore, analista, progettista, programmatore, responsabile, verificatore}
\end{axis}
\end{tikzpicture}
\caption{Ore per componente, periodo di analisi}
\end{figure}

chapter2

\pgfplotsset{
ybar, 
enlargelimits =0.10,
legend style ={at={(0.5,-0.5)},
anchor=north,
legend columns=-1},
ylabel={Ore},
xtick=data,
x tick label style={rotate=45,anchor=east},
symbolic x coords={Amministratore, Analista, Progettista, Programmatore, Responsabile, Verificatore},
}


    \begin{figure}[H]
\centering
\begin{tikzpicture}
\begin{axis}
\input{columnChart_consuntivo_rr}
\legend{preventivate,consumate}
\end{axis}
\end{tikzpicture}
\caption{Differenza preventivo consuntivo per ruolo, periodo di analisi}
\end{figure}

The problem is that chapter2 use ybar stacked option which is in chapter1 file.

Answer 1

You can deactivate the stacking by setting stack plots=false:

\documentclass{article}
\usepackage{pgfplots}
\pgfplotsset{compat=1.9, samples=5}

\begin{document}

\pgfplotsset{ybar stacked}
\begin{tikzpicture}
\begin{axis}
\addplot {rnd};
\addplot {rnd};
\end{axis}
\end{tikzpicture}

\pgfplotsset{ybar, stack plots=false}
\begin{tikzpicture}
\begin{axis}
\addplot {rnd};
\addplot {rnd};
\end{axis}
\end{tikzpicture}
\end{document}

Alternatively, you can keep the ybar stacked option local by supplying it to the axis environment directly, instead of setting it globally using \pgfplotsset:

\documentclass{article}
\usepackage{pgfplots}
\pgfplotsset{compat=1.9, samples=5}

\begin{document}

\begin{tikzpicture}
\begin{axis}[ybar stacked]
\addplot {rnd};
\addplot {rnd};
\end{axis}
\end{tikzpicture}

\begin{tikzpicture}
\begin{axis}[ybar]
\addplot {rnd};
\addplot {rnd};
\end{axis}
\end{tikzpicture}
\end{document}
