A '''polar rose plot''' (or '''roseplot''') is an angle histogram showing the distribution of values grouped according to their numeric range (viewed as a "polar plot"). It is similar to a [[wikipedia:Rose_%28mathematics%29|polar rose]] (i.e. with <tt>r = cos(k*θ</tt>)) but not necessarily symmetric, as the symmetry (or "direction" of petals) is entirely dependant on the input data.

A roseplot is useful for viewing the "direction" of input data. It is commonly used for plotting the daily (or yearly, etc.) average wind direction (sometimes called a "wind direction plot").

I routinely use roseplots in my [[:Category:Bioinformatics|bioinformatics]] [[:Category:Academic Research|research]]. They are especially useful for getting an overview of amino acid or nucleotide usage in a given genome (note: to see what I mean, have a look at the Genome Atlas at CBS).

 A roseplot is useful for viewing the "direction" of input data. It is commonly used for plotting the daily (or yearly, etc.) average wind direction at a given location (sometimes called a "wind direction plot" or a "wind rose").
 Roseplots display degree, radian, or grad data versus a radial axis. Like histograms, roseplots display statistical data, showing the number of occurrences of an event that fall within a specific angular region.
