pgfplots: Ocultar curvas do gráfico

Question

Existe uma maneira de ocultar as duas primeiras curvas para que apenas o Total seja mostrado?

Infelizmente, forget plotexclui apenas uma curva de ser listada na legenda.

\documentclass{standalone}

\RequirePackage{pgfplots}

\begin{document}

\begin{tikzpicture}
    \begin{axis}[stack plots=y,
    legend pos=outer north east,
    minor x tick num=1,
    minor y tick num=1,
    ymin=0,
    grid=both,
    ] 
        \addplot [forget plot, line width=0pt] coordinates {(0,1) (1,1) (2,2) (3,2)};  % HIDE from graph but use for Total
        \addplot [forget plot, line width=0pt] coordinates {(0,1) (1,1) (2,2) (3,2)};  % HIDE from graph but use for Total
        \addplot [line width=2pt, mark=*] coordinates {(0,1) (1,1) (2,2) (3,2)}; 

        \legend{Total}
    \end{axis} 
\end{tikzpicture}

\end{document}

Mesmo com line width=0pt, essas linhas ainda são visíveis ...

Qualquer ajuda é apreciada. Obrigado!

Você pode usar draw=none:

\documentclass{standalone}

\RequirePackage{pgfplots}

\begin{document}

\begin{tikzpicture}
    \begin{axis}[stack plots=y,
    legend pos=outer north east,
    minor x tick num=1,
    minor y tick num=1,
    ymin=0,
    grid=both,
    ] 
        \addplot [forget plot, draw=none] coordinates {(0,1) (1,1) (2,2) (3,2)};  % HIDE from graph but use for Total
        \addplot [forget plot, draw=none] coordinates {(0,1) (1,1) (2,2) (3,2)};  % HIDE from graph but use for Total
        \addplot [line width=2pt, mark=*] coordinates {(0,1) (1,1) (2,2) (3,2)}; 

        \legend{Total}
    \end{axis} 
\end{tikzpicture}

\end{document}
