IDataLabel.PositionXls Property
Position of the label, assuming margins in the plot area. This value is only set in xls files, and has different meanings depending on the kind of label:
In titles, x and y are the offset from the chart position in units of 1/4000 of the position.
In axis titles, x means offset perpendicular to the axis, in units of 1/1000 of the plot-area bounding box, and y means offset parallel to the axis, in units of 1/1000 of the axis length.
In data labels for pie charts, x is the offset angle from the default, in degrees clockwise, while y is the radial offset, in units of 1/1000 of the pie radius.
In data labels for bar and column charts, x is the offset perpendicular to the bar or column, in units of 1/1000 of the plot area, while y is the offset parallel to the bar or column, in units of 1/1000 of the plot area.
For other charts, x is the horizontal offset from the default position, in units of 1/1000 of the plot area and y is vertical offset from the default position, in units of 1/1000 of the plot area.
