Visibility - defines the visibility of the axis. Possible values are:

Automatic - the axis will automatically shown, if the chart Z dimension is Categorical and has at least two categories or the chart Z dimension is Numeric. For charts with Z dimension One the depth axis is hidden.
Visible - the axis is always visible.
Hidden - the axis is always hidden.

Scale Mode - defines the type of scale used on this axis. Possible values are:

Automatic - the axis will automatically determine the scale type based on the charting areas displayed on it. In general chart areas of type "Series" or similar (Stacked, Clustered) use Categorical scale whereas chart area of type "XYZ Scatter" or similar use Numeric scale.
Cluster- the axis will always use numeric scale (number, date time, value timeline or range timeline).
Categorical - the axis will always use categorical scale.

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 left Y axis will have Left orientation (labels are positioned on the left side of the plot area), whereas a right Y axis will typically have right orientation - labels are positioned on the right side of the plot are. 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 depth axis. Possible values area:

Bottom Right - positions the axis at the bottom right chart edge (default)
Left Top - positions the axis at the left top chart edge
Cross - the axis is positioned according to the X and Y crossing settings (see below).

X Cross - defines the X crossing mode. Only applicable if Position is set to Cross. Possible values are:

Primary X At Value - crosses the primary X axis at the value specified by X Value
Primary X At Percent - crosses the primary X axis at the percent specified by X Percent
Secondary X At Value - crosses the secondary X axis at the value specified by X Value
Secondary X At Percent - crosses the secondary X axis at the percent specified by X Percent

X Value - specifies the value of the X axis (Primary or Secondary) at which to position the depth axis. This property is only applicable when Position is set Cross and X Cross is set to some of the Cross At Value modes.

X Percent - specifies the percent along the X axis length (Primary or Secondary) at which to position the depth axis. This property is only applicable when Position is set Cross and X Cross is set to some of the Cross At Percent modes.

Y Cross - defines the Y crossing mode. Only applicable if Position is set to Cross. Possible values are:

Primary Y At Value - crosses the primary Y axis at the value specified by Y Value
Primary Y At Percent - crosses the primary Y axis at the percent specified by Y Percent
Secondary Y At Value - crosses the secondary Y axis at the value specified by Y Value
Secondary Y At Percent - crosses the secondary Y axis at the percent specified by Y Percent

Y Value - specifies the value of the Y axis (Primary or Secondary) at which to position the depth axis. This property is only applicable when Position is set Cross and Y Cross is set to some of the Cross At Value modes.

Y Percent - specifies the percent along the Y axis length (Primary or Secondary) at which to position the depth axis. This property is only applicable when Position is set Cross and Y Cross is set to some of the Cross At Percent modes.
