PSROSE

file

Name of ASCII [or binary, see −b] data file. If no file is given, psrose will read standard input.

−A

Gives the sector width in degrees for sector and rose diagram. [Default 0 means windrose diagram]. Append r to draw rose diagram instead of sector diagram.

−B

Sets map boundary annotation and tickmark intervals; see the psbasemap man page for all the details. Remember that "x" here is radial distance and "y" is azimuth. The ylabel may be used to plot a figure caption.

−C

Plot vectors showing the principal directions given in the modes file. If no file is given, compute and plot mean direction.

−D

Shift sectors so that they are centered on the bin interval (e.g., first sector is centered on 0 degrees).

−E

Sets the viewpoint’s azimuth and elevation [180/90]

−F

Do not draw the scale length bar [Default plots scale in lower right corner]

−G

Selects shade, color or pattern for filling the sectors [Default is no fill]. (See SPECIFYING FILL below).

−H

Input file(s) has header record(s). If used, the default number of header records is N_HEADER_RECS. Use −Hi if only input data should have header records [Default will write out header records if the input data have them]. Blank lines and lines starting with # are always skipped.

−I

Inquire. Computes statistics needed to specify useful −R. No plot is generated.

−K

More PostScript code will be appended later [Default terminates the plot system].

−L

Specify labels for the 0, 90, 180, and 270 degree marks. For full-circle plot the default is WEST/EAST/SOUTH/NORTH and for half-circle the default is 90W/90E/-/0. A - in any entry disables that label. Use −L with no argument to disable all four labels

−M

Specify new arrow attributes tailwidth/headlength/headwidth/r/g/b to change the appearance of arrows (Only if −C is set). [Default is 0.075c/0.3c/0.25c/0/0/0 (or 0.03i/0.12i/0.1i/0/0/0)].

−O

Selects Overlay plot mode [Default initializes a new plot system].

−P

Selects Portrait plotting mode [Default is Landscape, see gmtdefaults to change this].

−R

Specifies the ’region’ of interest in (r,azimuth) space. r0 is 0, r1 is max length in units. For azimuth, specify -90/90 for half circle plot or 0/360 for full circle.

−S

Specifies radius of circle. Append n to normalize input radii to go from 0 to 1.

−T

Specifies that the input data is orientation data (has a 180 degree ambiguity) instead of true 0-360 degree directions [Default].

−U

Draw Unix System time stamp on plot. By adding just/dx/dy/, the user may specify the justification of the stamp and where the stamp should fall on the page relative to lower left corner of the plot. For example, BL/0/0 will align the lower left corner of the time stamp with the lower left corner of the plot. Optionally, append a label, or c (which will plot the command string.). The GMT parameters UNIX_TIME, UNIX_TIME_POS, and UNIX_TIME_FORMAT can affect the appearance; see the gmtdefaults man page for details. The time string will be in the locale set by the environment variable TZ (generally local time).

−V

Selects verbose mode, which will send progress reports to stderr [Default runs "silently"].

−W

Set pen attributes for sector outline or rose plot. [Default is no outline]. (See SPECIFYING PENS below).

−X −Y

Shift plot origin relative to the current origin by (x-shift,y-shift) and optionally append the length unit (c, i, m, p). You can prepend a to shift the origin back to the original position after plotting, or prepend r [Default] to reset the current origin to the new location. If −O is used then the default (x-shift,y-shift) is (0,0), otherwise it is (r1i, r1i) or (r2.5c, r2.5c). Alternatively, give c to align the center coordinate (x or y) of the plot with the center of the page based on current page size.

−Z

Multiply the data radii by scale. E.g., use −Z 0.001 to convert your data from m to km [Default is no scaling].

−:

Input file has (azimuth,radius) pairs rather than the expected (radius,azimuth).

−bi

Selects binary input. Append s for single precision [Default is d (double)]. Uppercase S or D will force byte-swapping. Optionally, append ncol, the number of columns in your binary input file if it exceeds the columns needed by the program. Or append c if the input file is netCDF. Optionally, append var1/var2/... to specify the variables to be read. [Default is 2 input columns].

−c

Specifies the number of plot copies. [Default is 1].

pen

The attributes of lines and symbol outlines as defined by pen is a comma delimetered list of width, color and texture, each of which is optional. width can be indicated as a measure (points, centimeters, inches) or as faint, thin[ner|nest], thick[er|est], fat[ter|test], or obese. color specifies a gray shade or color (see SPECIFYING COLOR below). texture is a combination of dashes ‘-’ and dots ‘.’.

fill

The attribute fill specifies the solid shade or solid color (see SPECIFYING COLOR below) or the pattern used for filling polygons. Patterns are specified as pdpi/pattern, where pattern gives the number of the built-in pattern (1-90) or the name of a Sun 1-, 8-, or 24-bit raster file. The dpi sets the resolution of the image. For 1-bit rasters: use Pdpi/pattern for inverse video, or append :Fcolor[B[color]] to specify fore- and background colors (use color = - for transparency). See GMT Cookbook & Technical Reference Appendix E for information on individual patterns.

color

The color of lines, areas and patterns can be specified by a valid color name; by a gray shade (in the range 0−255); by a decimal color code (r/g/b, each in range 0−255; h-s-v, ranges 0−360, 0−1, 0−1; or c/m/y/k, each in range 0−1); or by a hexadecimal color code (#rrggbb, as used in HTML). See the gmtcolors manpage for more information and a full list of color names.
