Niner710 has asked for the wisdom of the Perl Monks concerning the following question:

Hi, I am having trouble installing perl module GD on my Windows XP system. First, I downloaded the GD module(GD-2.41) from CPAN and tried to run the perl makefile.pl but I got an error.
'gdlib-config' is not recognized as an internal or external command, operable program or batch file. **UNRECOVERABLE ERROR** Could not find gdlib-config in the search path. Please install libgd 2 +.0.28 or h igher. If you want to try to compile anyway, please rerun this script with th +e option - -ignore_missing_gd.
How do I install gdlib on my windows xp machine? I thought the GD module had it self contained? Also, if I were to get everything installed correctly would it be possible to package my script and these libraries together to make a executable file? Sorry for the newbie questions. Any help would be very much appreciated? Thanks.

Hi, I want to create a simple 2D line plot with perl for the data that I crunch. I am using Windows XP and was wondering if anyone could give me a good perl module to use to do this. Thanks.

    If you want to install Perl/Tk you can use it's canvas to make 2d plots.

    I would advice gnuplot, or rather wgnuplot because you use Windows. Beware, there are lots of modules on CPAN for working with gnuplot but they donīt work well with Windows or donīt work at all with Windows. Fortunately itīs simple to generate gnuplot parameter files with plain Perl. You can generate a file containing the to be plotted data, i.e. the x,y values.

    QED example (untested): use Perl to generate a gnuplot.gp file containing all the stuff gnuplot needs to know.

    set datafile separator "," set xdata time set timefmt "%Y-%m-%dT%H:%M:%S" set term push set terminal png medium size 1200 800 set output './thePlot.png' plot [][-10:40] 'thePlot.csv' using 1:80 title "your title" with line +s title "plot title" with lines; set output set term windows

    After you have generated you call wgnuplot from the Perl script, something like:

    @args = ("gnuplot",$plot_parameters_file); system(@args) == 0 or die "gnuplot failed: $?";
