NAME
       PDL::Graphics::PGPLOTOptions - Setting PGPLOT options

SYNOPSIS
       use PGPLOTOptions qw('default_options');

DESCRIPTION
       This package contains one function (at present) which
       returns PDL::Option objects for default settings for plot
       windows and plot commands. This should be complemented by
       functions that could affect this such as file reading com-
       mands etc.

OPTIONS
       The following is a listing of options that are set in this
       file and what they do and what their default value is

       Window specfic options

       These options modify the appearance of windows and can
       also modify the default settings for creation of plot axes
       etc.

       Device
           The default PGPLOT device to use. The default value is
           set to the PGPLOT_DEV environment variable if set,
           otherwise to '?'.

       AxisColour
           The colour with which to draw axes. Default value=3
           (Green)

       HardLW, HardCH, HardFont, HardAxisColour, HardColour
           The linewidth, character height, font and axis colour
           to use on hardcopy devices. The default values are
           HardLW=4, HardCH=1.4, HardFont=2 (Roman), HardAxis-
           Colour=1 (Black) and HardColour=1 as well. The latter
           is the default plot colour to use on hardcopy devices.

       Axis
           The axis style to use. See the PDL::Graph-
           ics::PGPLOT::Window documentation for details. It
           defaults to 'Normal' which is a labelled box. Valid
           arguments are 'Empty', 'Box', 'Normal', 'Axes',
           'Grid', 'LogX', 'LogY', 'LogXY'.

       AspectRatio
           The aspect ratio of the output device. The default
           value is device dependent.

       WindowWidth
           The width of the output window in inches and defaults
           to as big as possible.

       WindowXSize and WindowYSize
           These are alternatives to AspectRatio and WindowWidth.

       WindowName
           The name of the window - can later be retrieved using
           name(). It defaults to 'Window'+Window ID.

       NXPanel
           The number of panels in the X-direction - defaults to
           1

       NYPanel
           The number of panels in the Y-direction - defaults to
           1

       Justify
           A boolean value which, if true, causes both axes to
           drawn to the same scale; see the PGPLOT "pgenv()" com-
           mand for more information.

       Border
           Adjust the spacing around the plot. See the documenta-
           tion in PDL::Graphics::PGPLOT::Window for details.

       CharSize
           The default charsize for the plot - used when annotat-
           ing the axes for instance. It defaults to 1.

       PlotPosition
           The position of the plot in normalised coordinates.

       Erase
           Explicitly erase the plotting surface, normally
           required when making new plots with PlotPosition.

       Plot specific options

       For the moment see the "PDL::Graphics::PGPLOT::Window"
       documentation for these.

       set_pgplot_options

       This function allows the user to set the default PGPLOT
       options. It is particularly useful in the ".perldlrc" file
       since one can do

         use PDL::Graphics::PGPLOTOptions ('set_pgplot_options');
         set_pgplot_options('Device' => '/xs', 'HardLW' => 3);

       for instance to set the default values. The main drawback
       is that the routine is rather unflexible with no synonyms
       or case-insensitivity.
