NAME

PDL::Graphics::PGPLOTOptions - Setting PGPLOT options

CONTENTS

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=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.
