[NTG-context] gnuplot: `! Undefined control sequence.` with format specifier %

11 Dec 2011

      Dear Mojca and ConTeXt folks,

I compiled gnuplot 4.5 from source (master) and got everything running.
Mojca, thank you so much!

Trying the example from the gnuplot page in the Wiki [1]

        \usemodule[gnuplot]

        \setupGNUPLOT[terminal=mp,option=color]

        % general settings for the whole document
        \startGNUPLOTinclusions

           # you may use TeX commands to format the titles and axes
           set title '\bf Trigonometry'
           set xlabel '$x$'
           set ylabel '$y$'
           set format y '\%.1f'
        \stopGNUPLOTinclusions

        \startGNUPLOTscript[tan]
           plot tan(x) t '$\tan(x)$'
        \stopGNUPLOTscript

        \startGNUPLOTscript[sin]
           plot 4*sin(x)+x t '$4\sin(x)+x$', x t '$x$' lt 3
        \stopGNUPLOTscript

        \useGNUPLOTgraphic[tan]
        \useGNUPLOTgraphic[sin][width=10cm]

even with the comments removed as above I get the following though.

        [1.1] [1.1] [1.1]
        ! Undefined control sequence.
        l.66 \0
               .0%
        ? 
        [1.1]
        ! Undefined control sequence.
        l.71 \1
               0.0%
        ? 
        [1.1]
        ! Undefined control sequence.
        l.76 \2
               0.0%
        ? 
        [1.1]
        ! Undefined control sequence.
        l.81 \3
               0.0%
        ? ^C! Interruption.
        <to be read again> 
                           0
        l.81 \30
                .0%
        ?

I hope that is not related to the used ConTeXt version.

        ConTeXt  ver: 2011.11.25 21:29 MKII  fmt: 2011.11.25  int: english/english

Actually I hope that it is since then upgrading would fix my issue. ;-)

Thanks,

Paul
