Abstract

sunflower draws density distribution sunflower plots. These plots are useful for displaying bivariate data whose density is too great for conventional scatter plots to be effective. A sunflower is a number of line segments of equal length, called petals, that radiate from a central point. There are two varieties of sunflowers: light and dark. Each petal of a light sunflower represents one observation. Each petal of a dark sunflower represents a specific number of observations specified by the user. The program uses dark and light sunflowers to represent high and medium density regions of the data, and dots or circles to represent individual observations in low density regions. This routine is built in to Stata as of version 8.1.
