PDL::Graphics::PGPLOTOptions - Setting PGPLOT options
use PGPLOTOptions qw('default_options');
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.
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.
The default PGPLOT device to use. The default value is set to the PGPLOT_DEV
environment variable if set, otherwise to '?'.
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
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'.
The aspect ratio of the output device. The default value is device dependent.
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.
The name of the window - can later be retrieved using name(). It defaults to
The number of panels in the X-direction - defaults to 1
The number of panels in the Y-direction - defaults to 1
A boolean value which, if true, causes both axes to drawn to the same scale; see the
PGPLOT "pgenv()" command for more information.
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.
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
Adjust the spacing around the plot. See the documentation in
PDL::Graphics::PGPLOT::Window for details.
The default charsize for the plot - used when annotating the axes for instance. It
defaults to 1.
The position of the plot in normalised coordinates.
Explicitly erase the plotting surface, normally required when making new plots with
Plot specific options
For the moment see the "PDL::Graphics::PGPLOT::Window" documentation for these.
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.
