^ or just - Print a short message about the syntax of the command, then exits (NOTE: on Windows just use -). ) Select input columns (0 is first column). ) Replace input columns that equal nodata with NaN. : Input file has (azimuth,radius) pairs rather than the expected To exclude the radii fromĬonsideration, set them all to unity with -Zu [Default is no E.g., use -Z0.001 toĬonvert your data from m to km. Z u| scale Multiply the data radii by scale. Use -Wv pen to change pen used to draw vector W pen Set pen attributes for sector outline or rose plot. Ignored if range is given as -90/90 or 0/180. WeĬompensate by counting each record twice: First as azimuth and secondĪs azimuth + 180. T Specifies that the input data are orientation data (i.e., have a 180 degreeĪmbiguity) instead of true 0-360 degree directions. Value so all adii (or bin counts) range from 0 to 1.
Use -Sn to normalize input radii (or bin counts if -A is used) by the largest S plot_radius Specifies radius of plotted circle (append a unit from c| i| p).
#Is a rose diagram a histogram full#
For azimuth, specify either -90/90 or 0/180įor half circle plot or 0/360 for full circle. R r0/ r1/ az_0/ az_1 Specifies the ‘region’ of interest in (r,azimuth) space. Using -M will add vector heads to all individual directions Given and the current plot mode is to draw a windrose diagram then See VECTORĪTTRIBUTES for specifying additional attributes. For vector heads,Īppend vector head size. Use -L with no argument to disable all four labels -M parameters Used with -C to modify vector parameters. Forįull-circle plot the default is WEST/EAST/SOUTH/NORTH and for L Specify labels for the 0, 90, 180, and 270 degree marks. N, mean az, mean r, mean resultant length, max bin sum, The following statistics are written to stdout: Computes statistics needed to specify a useful -R.
F Do not draw the scale length bar -G fill Selects shade, color or pattern for filling the sectors K. D Shift sectors so that they are centered on the bin interval (e.g.,įirst sector is centered on 0 degrees). Alternatively, specify -Cm to compute and plot mean direction. C m| mode_file Plot vectors showing the principal directions given in the mode_fileįile. The scale bar length is determined by the radial gridline spacing.
