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

Automatic - the axis will automatically shown, if at least one series is displayed on it.
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 "XY Scatter" or similar (XY Scatter Stacked, XY Scatter Cluster) 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.

Begin Percent - defines the start of the X axis in percents of the chart X size.

End Percent - defines the end of the X axis in percents of the chart X size.

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 Y axis. Possible values area:

Left - positions the axis at the left chart side (default for PrimaryY axis)
Right - positions the axis at the right chart side (default for SeconaryY axis)
Cross - the axis is positioned according to the Y and Depth crossing settings (see below).

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 X 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 X axis. This property is only applicable when Position is set Cross and Y Cross is set to some of the Cross At Percent modes.

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

At Value - crosses the depth axis at the value specified by Depth Value
At Percent - crosses the depth axis at the percent specified by Depth Percent

Depth Value - specifies the value of the depth axis at which to position the Y axis. This property is only applicable when Position is set Cross and Depth Cross is set to At Value.

Depth Percent - specifies the percent along the depth axis at which to position the Y axis. This property is only applicable when Position is set Cross and Depth Cross is set to At Percent.
