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 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, Hard- Font=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. perl v5.8.0 2002-08-15 PGPLOTOptions(3)
