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 radii (or bin counts) range from 0 to 1. S Normalize input radii (or bin counts if -A is used) by the largest

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. Requires at least 10 points the critical resultants are accurate Note: The critical values are approximated and Is significant (i.e., Lord Rayleigh test for uniformity). Q alpha ] Sets the confidence level used to determine if the mean resultant 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. M parameters Used with -E to modify vector parameters. Note that the GMT_LANGUAGE setting will affect the words used. Use -L with no argument to disable all four labels. Forįull-circle plot the default is WEST,EAST,SOUTH,NORTH and for L Specify labels for the 0, 90, 180, and 270 degree marks. If not given we default to 6 inches (or 7.5 cm). Only this form of the projection machinery JX diameter Sets the diameter of the rose diagram. 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. ) Selects shade, color or pattern for filling the sectors. F Do not draw the scale length bar -G fill (more. Mean_az, mean_r, mean_resultant, max_r, scaled_mean_r, length_sum, n, the last term is 0 or 1 depending on whether the mean resultant is significantĪt the level of confidence set via -Q. The eight items saved to a single record are: Finally, to instead save theĬomputed mean direction and other statistics, use +w mode_file. Alternatively, specify -Em to compute and plot mean direction. E m| mode_file Plot vectors showing the principal directions given in the mode_fileįile. D Shift sectors so that they are centered on the bin interval (e.g.,įirst sector is centered on 0 degrees). The scale bar length is determined by the radial gridline spacing.
