[Graph-dev] passing multiple datasets into gnuplot module

[J. J. Yuan]

It still doesn't work.  I wonder if this has to do with Gnuplot or Perl on
my box?  The examples worked fine!

Here is my complete program:

#!/usr/bin/perl -w

# To include extra perl modules (DBI, DBD::Sybase, POSIX, Gnuplot, etc.)
BEGIN { unshift @INC, '/sysadmin/collector/src/module',
	'/sysadmin/collector/src/module/aix',
	'/sysadmin/collector/src/new_web/cgi-bin',
	'/sysadmin/collector/src/module/lib/site_perl/5.6.0/',
	'/sysadmin/collector/src/module/lib/site_perl/5.6.1'}

use Chart::Graph::Gnuplot qw(gnuplot);

%hash1 = {"title" => "data1",
		"type" => "matrix"};

%hash2 = {"title" => "data2",
		"style" => "lines",
		"type" => "columns"};

@array1 = ([1, 10], [2, 20], [3, 30]);

@array2 = ([8, 26, 50, 60, 70], [5, 28, 50, 60, 70]);

push @dataset, [\%hash1, \@array1], [\%hash2, \@array2];


gnuplot({"title" => "foo",
		 "x2-axis label" => "bar",
		 "logscale x2" => "1",
		 "logscale y" => "0",
		 "output type" => "png",
		 "output file" => "gnuplot1.png",
		 "xdata" => "time",
		 "format" => ["x", "%m/%d"],
		 "timefmt"=> "%H:%M",
		 "extra_opts" => "set key left top Left"},
		 @dataset);

====================================================================
Here is the error on my terminal screen:
