Structural Diagrams

Structural Rose Diagrams

  • This is a circular histogram displaying binned directional/orientational data. Rose diagram requires K = 1 trend or azimuth variable in which the data should be stored in degrees and can vary from 0-360° for directional data, or 0-180° for orientational data (with data above 180°, Aabel will take the modulus 180 of all values)
  • The rose graph types include full circle (symmetric for orientational data, or asymmetric for directional data) and half circle.

  • Treating the rose variable as directional data will generate an asymmetric rose diagram.
