Agregue selectivamente entradas de leyenda para trazar en CSV grande

Question

Tengo una trama con 63 líneas, solo para algunas de las cuales me gustaría tener entradas de leyenda. La leyenda completa ocupa media página y el uso del \refmétodo no me da coherencia con las tramas circundantes. estoy usando unmuyVersión pirateada y modificada de la trama de leyenda automática de Jake (https://tex.stackexchange.com/a/24023/4621) con algo de coloración automática y algunos gráficos rellenos para el intervalo de confianza.

Probé esto con etoolboxde \ifinlistuna lista creada con \forcsvlist, pero las entradas de leyenda que se agregan tienen el color incorrecto.

¿Algunas ideas?

Sin los \ifinlistbits funciona perfectamente, pero solo quiero agregar entradas de leyenda para ciertas líneas (columnas/lo que sea).

Aquí está la función que hace parcialmente la magia:

\newcommand*{\plotFileRainbowCertaintyLegendList}[5]{
  \begin{tikzpicture}
    \begin{axis}[
        %Unboxed,
        %Dates,
        %twocolumn,
        y tick label style={/pgf/number format/fixed},
        xlabel={},
        legend columns = 3,
        legend style={at={(0.5,-0.1)},anchor=north},
        #4
      ]
    %By column number
    \forcsvlist{\listadd\LegendList}{50,52,53,56}
    %By column name
    %\forcsvlist{\listadd\LegendList}{col1Name,col2Name,etc...}

    \pgfplotstableread{#1}\Mod
    \pgfplotstableread{#2}\ModLow
    \pgfplotstableread{#3}\ModHigh


    \def\WaveLow{360}
    \def\WaveHigh{660}

    \pgfplotstablegetcolsof{\Mod}
    \pgfmathtruncatemacro\numberofcols{\pgfplotsretval-1}
    \pgfmathsetmacro{\waveStep}{(\WaveHigh-\WaveLow)/\numberofcols}

      \pgfplotsinvokeforeach{1,...,\numberofcols}{
        \pgfmathparse{\WaveLow+##1*\waveStep}
        \definecolor{Offence##1}{wave}{\pgfmathresult}

          \addplot+[Offence##1!50,opacity=0.01,name path=confLow, mark = none, line width = 0, forget plot,#5] table [y index=##1] \ModLow ;
          \addplot+[Offence##1!50,opacity=0.01,name path=confHigh, mark = none, line width = 0, forget plot,#5] table [y index=##1] \ModHigh ;
          \addplot[Offence##1!70,opacity=0.5, forget plot,#5] fill between[of=confLow and confHigh];

        \pgfplotstablegetcolumnnamebyindex{##1}\of{\Mod}\to{\colname}
        \addplot+[Offence##1,solid,thick,mark=none,#5] table [y index=##1] {\Mod};
        %By column number
        \xifinlist{##1}{\LegendList}{\addlegendentryexpanded{\colname};}{}
      }
        %By column name
        %\xifinlist{\colname}{\LegendList}{\addlegendentryexpanded{\colname};}{}
      %}
    \end{axis}
  \end{tikzpicture}
}

Esto puede hacerse. Para más detalles, eche un vistazo a los comentarios en el código.
