rose
Angle histogram plot
rose is not recommended. Use polarhistogram instead.
Syntax
rose(theta)
rose(theta,x)
rose(theta,nbins)
rose(ax,...)
h = rose(...)
[tout,rout] = rose(...)
Description
rose(theta) creates an angle histogram, which is
a polar plot showing the distribution of values grouped according to their numeric range,
showing the distribution of theta in 20 angle bins or less. The vector
theta, expressed in radians, determines the angle of each bin from the
origin. The length of each bin reflects the number of elements in theta
that fall within a group, which ranges from 0 to the greatest number of elements deposited in
any one bin.
rose(theta,x) uses the vector
x to specify the number and the locations of bins.
length(x) is the number of bins and the values of x
specify the center angle of each bin. For example, if x is a five-element
vector, rose distributes the elements of theta in five
bins centered at the specified x values.
rose(theta,nbins) plots nbins
equally spaced bins in the range [0,2*pi]. The default is
20.
rose(ax,...) plots into the axes
ax instead of the current axes (gca).
h = rose(...) returns the handle of the line
object used to create the graph.
[tout,rout] = rose(...) returns the vectors
tout and rout so polar(tout,rout)
generates the histogram for the data. This syntax does not generate a plot.
Examples
Create Angle Histogram
Create an angle histogram of values between 0 and . Distribute the data among 10 bins.
theta = [0.4 1.4 3.1 2.3 0.4 2.5 3.9 2.8 2.3 1.6 4.6 4.5 6.1 3.9 5.1]; rose(theta,10)
