6 PDL::Graphics::PGPLOTOptions - Setting PGPLOT options
7
9 use PGPLOTOptions qw('default_options');
10
12 This package contains one function (at present) which returns
13 PDL::Option objects for default settings for plot windows and plot
14 commands. This should be complemented by functions that could affect
15 this such as file reading commands etc.
16
18 The following is a listing of options that are set in this file and
19 what they do and what their default value is
20 Window specific options
22 These options modify the appearance of windows and can also modify the
23 default settings for creation of plot axes etc.
24 Device
26 The default PGPLOT device to use. The default value is set to the
27 PGPLOT_DEV environment variable if set, otherwise to '?'.
28 AxisColour
30 The colour with which to draw axes. Default value=3 (Green)
31 HardLW, HardCH, HardFont, HardAxisColour, HardColour
33 The linewidth, character height, font and axis colour to use on
34 hardcopy devices. The default values are HardLW=1, HardCH=1.4,
35 HardFont=2 (Roman), HardAxisColour=1 (Black) and HardColour=1 as
36 well. The latter is the default plot colour to use on hardcopy
37 devices.
38 Axis
40 The axis style to use. See the PDL::Graphics::PGPLOT::Window
41 documentation for details. It defaults to 'Normal' which is a
42 labelled box. Valid arguments are 'Empty', 'Box', 'Normal', 'Axes',
43 'Grid', 'LogX', 'LogY', 'LogXY'.
44 AspectRatio
46 The aspect ratio of the output device. The default value is device
47 dependent.
48 WindowWidth
50 The width of the output window in inches and defaults to as big as
51 possible.
52 WindowXSize and WindowYSize
54 These are alternatives to AspectRatio and WindowWidth.
55 WindowName
57 The name of the window - can later be retrieved using name(). It
58 defaults to 'Window'+Window ID.
59 NXPanel
61 The number of panels in the X-direction - defaults to 1
62 NYPanel
64 The number of panels in the Y-direction - defaults to 1
65 Justify
67 A boolean value which, if true, causes both axes to drawn to the
68 same scale; see the PGPLOT "pgenv()" command for more information.
69 TightLabels
71 Boolean value which, if true, causes axis labels to be pulled
72 slightly closer to the main viewport than usual. That's handy for
73 making multi-panel plots. Undef (the default) is equivalent to 0
74 for panels with NYPanels <= 1 and 1 for panels with NYPanels > 1.
75 TitleSize
77 The relative size of a plot or image title, compared to other
78 annotations. Defaults to 1.0 (original behavior) but can be set
79 to, e.g., 1.5 to emphasize graph titles in a multipanel plot.
80 Border
82 Adjust the spacing around the plot. See the documentation in
83 PDL::Graphics::PGPLOT::Window for details.
84 CharSize
86 The default charsize for the plot - used when annotating the axes
87 for instance. It defaults to 1.
88 PlotPosition
90 The position of the plot in normalised coordinates.
91 Erase
93 Explicitly erase the plotting surface, normally required when
94 making new plots with PlotPosition.
95 Plot specific options
97 For the moment see the "PDL::Graphics::PGPLOT::Window" documentation
98 for these.
99 set_pgplot_options
101 This function allows the user to set the default PGPLOT options. It is
102 particularly useful in the ".perldlrc" file since one can do
103 use PDL::Graphics::PGPLOTOptions ('set_pgplot_options');
105 set_pgplot_options('Device' => '/xs', 'HardLW' => 3);
106 for instance to set the default values. The main drawback is that the
108 routine is rather unflexible with no synonyms or case-insensitivity.
