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 com‐
14 mands. This should be complemented by functions that could affect this
15 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 specfic options
22 These options modify the appearance of windows and can also modify the
24 default settings for creation of plot axes etc.
25 Device
27 The default PGPLOT device to use. The default value is set to the
28 PGPLOT_DEV environment variable if set, otherwise to '?'.
29 AxisColour
31 The colour with which to draw axes. Default value=3 (Green)
32 HardLW, HardCH, HardFont, HardAxisColour, HardColour
34 The linewidth, character height, font and axis colour to use on
35 hardcopy devices. The default values are HardLW=1, HardCH=1.4,
36 HardFont=2 (Roman), HardAxisColour=1 (Black) and HardColour=1 as
37 well. The latter is the default plot colour to use on hardcopy
38 devices.
39 Axis
41 The axis style to use. See the PDL::Graphics::PGPLOT::Window docu‐
42 mentation for details. It defaults to 'Normal' which is a labelled
43 box. Valid arguments are 'Empty', 'Box', 'Normal', 'Axes', 'Grid',
44 'LogX', 'LogY', 'LogXY'.
45 AspectRatio
47 The aspect ratio of the output device. The default value is device
48 dependent.
49 WindowWidth
51 The width of the output window in inches and defaults to as big as
52 possible.
53 WindowXSize and WindowYSize
55 These are alternatives to AspectRatio and WindowWidth.
56 WindowName
58 The name of the window - can later be retrieved using name(). It
59 defaults to 'Window'+Window ID.
60 NXPanel
62 The number of panels in the X-direction - defaults to 1
63 NYPanel
65 The number of panels in the Y-direction - defaults to 1
66 Justify
68 A boolean value which, if true, causes both axes to drawn to the
69 same scale; see the PGPLOT "pgenv()" command for more information.
70 TightLabels
72 Boolean value which, if true, causes axis labels to be pulled
73 slightly closer to the main viewport than usual. That's handy for
74 making multi-panel plots. Undef (the default) is equivalent to 0
75 for panels with NYPanels <= 1 and 1 for panels with NYPanels > 1.
76 TitleSize
78 The relative size of a plot or image title, compared to other anno‐
79 tations. Defaults to 1.0 (original behavior) but can be set to,
80 e.g., 1.5 to emphasize graph titles in a multipanel plot.
81 Border
83 Adjust the spacing around the plot. See the documentation in
84 PDL::Graphics::PGPLOT::Window for details.
85 CharSize
87 The default charsize for the plot - used when annotating the axes
88 for instance. It defaults to 1.
89 PlotPosition
91 The position of the plot in normalised coordinates.
92 Erase
94 Explicitly erase the plotting surface, normally required when mak‐
95 ing new plots with PlotPosition.
96 Plot specific options
98 For the moment see the "PDL::Graphics::PGPLOT::Window" documentation
100 for these.
101 set_pgplot_options
103 This function allows the user to set the default PGPLOT options. It is
105 particularly useful in the ".perldlrc" file since one can do
106 use PDL::Graphics::PGPLOTOptions ('set_pgplot_options');
108 set_pgplot_options('Device' => '/xs', 'HardLW' => 3);
109 for instance to set the default values. The main drawback is that the
111 routine is rather unflexible with no synonyms or case-insensitivity.
