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 commands 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 specific 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=1, HardCH=1.4,
	   HardFont=2 (Roman), HardAxisColour=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::Graphics::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()"	command	for more information.

       TightLabels
	   Boolean value which,	if true, causes	axis labels to be pulled
	   slightly closer to the main viewport	than usual.  That's handy for
	   making multi-panel plots.  Undef (the default) is equivalent	to 0
	   for panels with NYPanels <= 1 and 1 for panels with NYPanels	> 1.

       TitleSize
	   The relative	size of	a plot or image	title, compared	to other
	   annotations.	 Defaults to 1.0 (original behavior) but can be	set
	   to, e.g., 1.5 to emphasize graph titles in a	multipanel plot.

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

       CharSize
	   The default charsize	for the	plot - used when annotating 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.
