The default angular limits for a Rosette Plot are 45-90 degrees. The angular limits indicate the allowable (small) angle between the base plane or face and the planes in the data set. The default range ensures that only planes that are more perpendicular than parallel to the base plane will be used.
In the Rosette Options dialog, the minimum and maximum angular limits can be set to any pair of values from 0 to 90.
Only planes within these limits will be used to generate the plot.
