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
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)
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.
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.
These are alternatives to AspectRatio and WindowWidth.
The name of the window - can later be retrieved using name(). It defaults to 'Window'+Window ID.
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.
pgenv()
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.
Allows plotting multiple panels on one plot, normally used with 'PlotPosition'.
For the moment see the PDL::Graphics::PGPLOT::Window documentation for these.
