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. 

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.
