headLen | Length of the arrow head, from tip to base. default=20 |
headWidth | Width of the arrow head at its base. |
tipAngle | Angle of the tip of the arrow in degrees. Smaller values make a ‘sharper’ arrow. If tipAngle is specified, ot overrides headWidth. default=25 |
baseAngle | Angle of the base of the arrow head. Default is 0, which means that the base of the arrow head is perpendicular to the arrow tail. |
tailLen | Length of the arrow tail, measured from the base of the arrow head to the end of the tail. If this value is None, no tail will be drawn. default=None |
tailWidth | Width of the tail. default=3 |
