Star Plots

http://www.bmj.com/content/333/7565/413.full
Star plots allow you to view and compare multiple variables for each of your observations. Star plots use a given number of plotted domains in each plot and are typically used by an individual who is interested in testing relative values for a given data report. This star plot above is plotting domains for systematic reviews of diagnostic tests in cancer. Like with other star plots, this plot signifies the higher quality reviews recieved by illustrating longer lines on the plots. The lower quality reviews are shown with shorter lines or spokes and the lines are closer together. This is the main interest and focus with star plots, in that they are used to signify different characteristics.
