19 psrose reads (length,azimuth) pairs from file [or standard input] and
20 generates PostScript code that will plot a windrose diagram. Option‐
21 ally (with -A), polar histograms may be drawn (sector diagram or rose
22 diagram). Options include full circle and half circle plots. The
23 PostScript code is written to standard output.
24 file Name of ASCII [or binary, see -b] data file. If no file is
26 given, psrose will read standard input.
27
29 No space between the option flag and the associated arguments.
30 -A Gives the sector width in degrees for sector and rose diagram.
32 [Default 0 means windrose diagram]. Append r to draw rose dia‐
33 gram instead of sector diagram.
34 -B Sets map boundary annotation and tickmark intervals; see the
36 psbasemap man page for all the details. Remember that "x" here
37 is radial distance and "y" is azimuth. The ylabel may be used
38 to plot a figure caption.
39 -C Plot vectors showing the principal directions given in the modes
41 file. If no file is given, compute and plot mean direction.
42 -D Shift sectors so that they are centered on the bin interval
44 (e.g., first sector is centered on 0 degrees).
45 -E Sets the viewpoint's azimuth and elevation [180/90]
47 -F Do not draw the scale length bar [Default plots scale in lower
49 right corner]
50 -G Selects shade, color or pattern for filling the sectors [Default
52 is no fill]. (See SPECIFYING FILL below).
53 -H Input file(s) has header record(s). If used, the default number
55 of header records is N_HEADER_RECS. Use -Hi if only input data
56 should have header records [Default will write out header
57 records if the input data have them]. Blank lines and lines
58 starting with # are always skipped.
59 -I Inquire. Computes statistics needed to specify useful -R. No
61 plot is generated.
62 -K More PostScript code will be appended later [Default terminates
64 the plot system].
65 -L Specify labels for the 0, 90, 180, and 270 degree marks. For
67 full-circle plot the default is WEST/EAST/SOUTH/NORTH and for
68 half-circle the default is 90W/90E/-/0. A - in any entry dis‐
69 ables that label. Use -L with no argument to disable all four
70 labels
71 -M Specify new arrow attributes tailwidth/headlength/head‐
73 width/r/g/b to change the appearance of arrows (Only if -C is
74 set). [Default is 0.075c/0.3c/0.25c/0/0/0 (or
75 0.03i/0.12i/0.1i/0/0/0)].
76 -O Selects Overlay plot mode [Default initializes a new plot sys‐
78 tem].
79 -P Selects Portrait plotting mode [Default is Landscape, see gmtde‐
81 faults to change this].
82 -R Specifies the 'region' of interest in (r,azimuth) space. r0 is
84 0, r1 is max length in units. For azimuth, specify -90/90 for
85 half circle plot or 0/360 for full circle.
86 -S Specifies radius of circle. Append n to normalize input radii
88 to go from 0 to 1.
89 -T Specifies that the input data is orientation data (has a 180
91 degree ambiguity) instead of true 0-360 degree directions
92 [Default].
93 -U Draw Unix System time stamp on plot. By adding just/dx/dy/, the
95 user may specify the justification of the stamp and where the
96 stamp should fall on the page relative to lower left corner of
97 the plot. For example, BL/0/0 will align the lower left corner
98 of the time stamp with the lower left corner of the plot.
99 Optionally, append a label, or c (which will plot the command
100 string.). The GMT parameters UNIX_TIME, UNIX_TIME_POS, and
101 UNIX_TIME_FORMAT can affect the appearance; see the gmtdefaults
102 man page for details. The time string will be in the locale set
103 by the environment variable TZ (generally local time).
104 -V Selects verbose mode, which will send progress reports to stderr
106 [Default runs "silently"].
107 -W Set pen attributes for sector outline or rose plot. [Default is
109 no outline]. (See SPECIFYING PENS below).
110 -X -Y Shift plot origin relative to the current origin by (x-shift,y-
112 shift) and optionally append the length unit (c, i, m, p). You
113 can prepend a to shift the origin back to the original position
114 after plotting, or prepend r [Default] to reset the current
115 origin to the new location. If -O is used then the default (x-
116 shift,y-shift) is (0,0), otherwise it is (r1i, r1i) or (r2.5c,
117 r2.5c). Alternatively, give c to align the center coordinate (x
118 or y) of the plot with the center of the page based on current
119 page size.
120 -Z Multiply the data radii by scale. E.g., use -Z0.001 to convert
122 your data from m to km [Default is no scaling].
123 -: Input file has (azimuth,radius) pairs rather than the expected
125 (radius,azimuth).
126 -bi Selects binary input. Append s for single precision [Default is
128 d (double)]. Uppercase S or D will force byte-swapping.
129 Optionally, append ncol, the number of columns in your binary
130 input file if it exceeds the columns needed by the program. Or
131 append c if the input file is netCDF. Optionally, append
132 var1/var2/... to specify the variables to be read. [Default is
133 2 input columns].
134 -c Specifies the number of plot copies. [Default is 1].
136 SPECIFYING PENS
138 pen The attributes of lines and symbol outlines as defined by pen is
139 a comma delimetered list of width, color and texture, each of
140 which is optional. width can be indicated as a measure (points,
141 centimeters, inches) or as faint, thin[ner|nest], thick[er|est],
142 fat[ter|test], or obese. color specifies a gray shade or color
143 (see SPECIFYING COLOR below). texture is a combination of
144 dashes `-' and dots `.'.
145 SPECIFYING FILL
147 fill The attribute fill specifies the solid shade or solid color (see
148 SPECIFYING COLOR below) or the pattern used for filling poly‐
149 gons. Patterns are specified as pdpi/pattern, where pattern
150 gives the number of the built-in pattern (1-90) or the name of a
151 Sun 1-, 8-, or 24-bit raster file. The dpi sets the resolution
152 of the image. For 1-bit rasters: use Pdpi/pattern for inverse
153 video, or append :Fcolor[B[color]] to specify fore- and back‐
154 ground colors (use color = - for transparency). See GMT Cook‐
155 book & Technical Reference Appendix E for information on indi‐
156 vidual patterns.
157 SPECIFYING COLOR
159 color The color of lines, areas and patterns can be specified by a
160 valid color name; by a gray shade (in the range 0-255); by a
161 decimal color code (r/g/b, each in range 0-255; h-s-v, ranges
162 0-360, 0-1, 0-1; or c/m/y/k, each in range 0-1); or by a hexa‐
163 decimal color code (#rrggbb, as used in HTML). See the gmtcol‐
164 ors manpage for more information and a full list of color names.
