Instead of points being plotted along an axis, bars are drawn to show the quantity of that variable. A common use of a rose graph is in showing wind speed or noise levels. The ‘axes’ for the graph are the directions of a compass and the speed of the wind or the decibel level is then drawn in the appropriate direction.

What is the period of a rose graph?

The curve has loops that are symmetrically distributed around the pole. The loops are called petals or leafs. If p and q are both odd, it has a period of π*q with p petals, otherwise the period is 2*π*q and has 2*p petals.
