in reply to Create a plot / chart with dates as x-values?

Ok, thanks, all. Chart::Gnuplot did exactly what I wanted:

#!/usr/bin/env perl use Modern::Perl; use DateTime; use Chart::Gnuplot; my @x_vals = qw/ 2012-11-07 2012-11-08 2012-11-15 2012-11-19 2012-11-30 /; my @y_vals = ( 11, 12, 13, 14, 15, ); my $chart = Chart::Gnuplot->new( output => 'plot.png', title => 'plot title', xlabel => 'x label', ylabel => 'y label', timeaxis => 'x', xtics => { labelfmt => '%Y-%m-%d', rotate => -90, }, ); my $dataset = Chart::Gnuplot::DataSet->new( xdata => \@x_vals, ydata => \@y_vals, title => 'data title', style => 'linespoints', timefmt => '%Y-%m-%d', ); $chart->plot2d($dataset);

[Corion]: That is a horrible approach that was also taken by Access, but if you have hooks that prevent automatic saving to the database, it is incredibly handy
