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

While working with PGPlot, I've run into a problem with graphing my data. I have not been able to figure out how to change the labels of the X-Axis. I want to be able to graph data over a period of time, ie. Time of Day, Day of month.
Help, Obi-PM-Kenobi your my only hope.

    To affect the numeric labels, you just need to scale that axis' numbers to suit your new units. To set the title, use the env method. From the PDL::Graphics::PGPLOT::Window pod:

    $rate_win = PDL::Graphics::PGPLOT::Window->new(Device => '/xw',
            Aspect => 1, WindowWidth => 5, NXPanel => 2);

$area_win = PDL::Graphics::PGPLOT::Window->new(Device => '/xw',
            Aspect => 1, WindowWidth => 5);

$rate_win->env(0, 10, 0, 1000, {XTitle => 'Days', YTitle => '#Rabbits'
+});
$rate_win->env(0, 10, 0, 100, {Xtitle=>'Days', Ytitle => 'Rabbits/day'
+});

$area_win->env(0, 1, 0, 1, {XTitle => 'Km', Ytitle => 'Km'});
# And theoretical prediction.
$rate_win->line(sequence(10), fibonacci(10), {Panel => [1, 1]});

      That isn't exactly what I was looking for. What I want is the ability to label my x-axis for each day, ie 08/23/2002 to 08/29/2002 or from 08:00 to 16:30.
