 public boolean ContainsValue{ get; set; }

Public Property ContainsValue() As Boolean

This defaults to false when creating a new Series.
The data label is considered disabled if this and ContainsBubbleSize, ContainsCategoryName, ContainsSeriesName, and ContainsValueAsPercentage are all false.
If the series category type is a scatter or bubble chart, then this property corresponds to the 'Y Value' option under 'Label Contains' in Excel.
