rose

Purpose

Angle histogram.

Synopsis

rose(theta)
rose(theta,n)
rose(theta,x)
[t,r] = rose(...)

Description

rose(theta) plots an angle histogram for the angles in theta, which must be in radians. The angle histogram is a plot in polar coordinates of the number of theta points or samples within each of 20 angle bins.

rose(theta,n) where n is a scalar, uses n equally spaced bins in the range [0, 2*pi].

rose(theta,x) where x is a vector, uses the bins specified in x. The values in x specify the center angle of each bin.

[t,r] = rose(...) returns the vectors t and r such that polar(t,r) is the histogram for the data. No plot is drawn.

Examples

Create a rose plot for one year of simulated wind direction measurements:

wind = 360*rand(365,1)
rose(wind*pi/180,24)  %histogram every 15 degrees
