A Rosette Plot is generated by selecting the Rosette
Plot
option from the toolbar or the View
menu.
The conventional rosette plot begins with a horizontal plane (represented by the equatorial (outer) circle of the stereonet). A radial histogram (with arc segments instead of bars) is overlain on this circle, indicating the density of planes intersecting this horizontal surface. The radial orientation limits (azimuth) of the arc segments correspond to the range of STRIKE of the plane or group of planes being represented by the segment. In other words, the rosette diagram is a radial histogram of strike density or frequency.

Equivalent pole density stereonet (contour plot).
Intersection of the joint planes with a horizontal section.
Radial histogram or rosette of the strike of the joint planes.
The rosette (figure 4) approximates the visual impression of the joint intersections with the horizontal plane (figure 3).
NOTES:
Dips has removed the requirement that the base plane of the rosette be horizontal. The plane can be oriented at any orientation in space – see the Sightline Normal to Rosette topic for details. The ROSETTE then represents the apparent orientation of the lines of intersection between the base plane of the ROSETTE and the planes in the data set.
You will notice that each arc segment on a Rosette Plot has an equal and opposite counterpart (180 degrees apart). The Rosette Plot in Dips does NOT differentiate between LEFT and RIGHT handed strike and places planes with strikes 180 degrees apart in the same "bin" ( a "bin" = range defined by one arc segment). By default in Dips, each bin is 10 degrees wide. The bin size can be changed in the Rosette Options dialog.
