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 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)
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),
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.
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.
