Rose.C—a program in “C” for producing high-quality Rose diagrams

Abstract ROSE.C is a program written in “C” to draw Rose diagrams of high quality using 24-pin dot-matrix printers. It can handle both unidirectional and bidirectional (axial) data, and also compute and print various statistical parameters such as the direction of the resultant, the circular variance, consistency ratio, and the mean angular deviation. The diagrams produced can be scaled up to a maximum size of 9.3 cm. A number of options, including a selection of nine different patterns to shade the Rose diagram, have been provided. One of them allows the user to control the pattern. The program is designed to run up to 20 datafiles in a batch, each with its own options.
