A default scale is set automatically so that all of the rosette falls inside the circle.
To enter a user-defined scaling for the Rosette Plot:
Clear the Automatic checkbox in the Rosette Options dialog.
Enter the desired number of planes per circle increment.
Note:
If the interval selected by the user is too small and some segments of the rosette extend past the outer circle, those rosette segments will be truncated.
If you are applying the Terzaghi Weighting to the Rosette Plot, note that the WEIGHTED and the UNWEIGHTED Rosette Plot can each have their own independently defined scaling.
