To plot Pole Vectors select the Pole
Vector Mode 
option.
To plot Dip Vectors select the Dip
Vector Mode 
option.
The planar data entered in the main Dips spreadsheet (Grid Data) can be plotted on the stereonet as either:
Pole Vectors
Dip Vectors
This is determined by the setting of the Pole / Dip Vector Mode option which is available in the View menu or the toolbar.
To plot Pole Vectors select the Pole
Vector Mode option.
To plot Dip Vectors select the Dip
Vector Mode option.
Pole / Dip Vector mode can also be changed in the Kinematic Analysis dialog (e.g. for Planar Sliding analysis you can use either pole or dip vectors).
Vector Plots
The Pole / Dip Vector mode affects the Vector plot options in the sidebar:
Basic vector plot (Pole Plot or Dip Vector)
Each of these options will plot either pole or dip vectors according to the mode setting.
Contour Plot
The contouring of vectors is also dependent on the mode setting. The contours will correspond to either pole or dip vectors according to the mode setting.
Pole / Dip Vector Mode and Sets
It is important to note that joint sets (created with the options in the Sets menu) can ONLY be defined in Pole Vector Mode. Creation of sets from dip vectors is not valid, and therefore all Set options are disabled in Dip Vector Mode. If you wish to define joint sets and the Set options are disabled, then you must switch to Pole Vector Mode first, you will then be able to define sets.
