rose diagram A circular histogram plot which displays directional data and the frequency of each class. Rose diagrams are commonly used in sedimentary geology to display palaeocurrent data (see PALAEOCURRENT ANALYSIS), or the orientation of particles. In structural geology rose diagrams are used to plot the orientation of joints and dykes. Wind directions and frequencies can also be plotted on rose diagrams.
