Visible - defines the visibility of the axis.

Orientation - defines the axis orientation. The axis orientation is the side where labels appear when looking at the axis scale from its start point. For example a typical polar value axis will have Left orientation (labels are positioned on the left side). Possible values are: 

Auto - the axis will automatically determine its orientation based on its position (see below). 
Left - the axis will always use left orientation regardless of its position.
Right - the axis will always use right orientation.

Position - defines the position of the polar value axis. Possible values area:

Cross 0 - the axis originates from the polar center and is directed towards the polar angle axis 0 angle position (e.g. crosses the angle axis at 0 degrees).

Cross 90 - the axis originates from the polar center and is directed towards the angle axis 90 angle position.

Cross 180 - the axis originates from the polar center and is directed towards the angle axis 180 angle position.

Cross 270 - the axis originates from the polar center and is directed towards the angle axis 270 angle position.

Left - the axis originates from the polar center Y position. Has vertical orientation and is positioned at the left side of the polar chart.

Right - the axis originates from the polar center Y position. Has vertical orientation and is positioned at the right side of the polar chart.

Top - the axis originates from the polar center X position. Has horizontal orientation and is positioned at the top side of the polar chart.

Bottom - the axis originates from the polar center X position. Has horizontal orientation and is positioned at the bottom side of the polar chart.

Show Reflection - specifies whether a mirror reflection of the axis should be displayed.
