Bless you brother, I completely missed the gnuplot => "path to exe" option. However, also in this case I get an Invalid Parameter - 90 error message.

    Based on your other reply, it seems that you are mixing "/" and "\" directory separators in your chart's file name. Try not to... :-)

    the file name should either be
    \tmp\NTEVfipQVM\plot or
    /tmp/NTEVfipQVM/plot but not
    \tmp\NTEVfipQVM/plot ...

      It's not me mixing up "/" and "\", judge for yourself:

      use strict;
use warnings;
use Chart::Gnuplot;

    my $chart = Chart::Gnuplot->new(
        output => "c:/tmp/test.png",
        title  => "Simple testing",
        xlabel => "My x-axis label",
        ylabel => "My y-axis label",
        gnuplot => "C:/gnuplot/binaries/wgnuplot.exe",
    );

    my $dataSet = Chart::Gnuplot::DataSet->new(
        func => "sin(x)"
    );

    $chart->plot2d($dataSet);
    
    print "Done...\n";

      Resulting in the familiar error message;-)

        try this:

use Chart::Gnuplot;

    my $chart = Chart::Gnuplot->new(

        gnuplot => 'C:\gnuplot\binaries\wgnuplot.exe',
    );

    my $dataSet = Chart::Gnuplot::DataSet->new(
        func => 'sin(x)'
    );

    $chart->plot2d($dataSet);
    
    print "Done...\n";

        (notice the single quotes and the backslashes...)

        What is the result?

    I'm starting to get the feeling that the gnuplot executable and wgnuplot.exe must take different arguments.

    Cheers,

    Hmm, works for me :/

    I used gp424win32.zip from here.

    I also removed DIR => '/tmp' from Gnuplot.pm, because I like my existing temp directory just fine.

      Hmm, I use exactly the same stuff. I think I redo the installation of both and try again. What Perl and what version of Chart::Gnuplot do you use?
