histograms with GnuplotIF ?

[hda]

Wise fellow monks!

I wonder if you had experience plotting histograms with gnuplot via Graphics::GnuplotIF.

Until now I am trying with something like this:

use Graphics::GnuplotIF;
my $plot = Graphics::GnuplotIF->new (
    style        => 'histogram', # one of the gnuplot line     styles 
+(see below)
    title        => "$mytitle",      # string
    xlabel       => '$myxlabel',     # string
    ylabel       => '$myylabel',     # string
    xrange       => [@myxrange],      # array reference; autoscaling, 
+if empty
    yrange       => [@myyrange],      # array reference; autoscaling, 
+if empty
    plot_titles  => [ "$titles" ],      # array of strings; titles use
+d in the legend
    persist      => 0,       # let plot windows survive after gnuplot 
+exits
                             # 0 : close / 1 : survive
    );

    $plot_glacier->gnuplot_plot_xy ( \@x, \@y );
    $plot_glacier->gnuplot_pause();

But it does not work (message = "Graphics::GnuplotIF (object 4): problem closing communication to gnuplot").
Histograms are supported in gnuplot since version 4.2, so perhaps it is only that they are not supported in GnuplotIF. I know it can be done with other modules, but right now I am just interested in using GnuploIF to avoid module-code-clutter. Your words will be appreciated!

Thanks in advance,

I tend to write a gnuplot file directly, haven't come across GnuPlotIF before, looks interesting though

However histograms are achieved with plot ...  using histeps not histogram ;)

Thanks for the reply. GnuplotIF and those in the Chart family are good interfaces, but I agree with you that it is better to use Perl to write the configuration text file and then call gnuplot via system.
