| [ClearFormat](./clearformat/)() | Clears format of this data label. The properties are set to the default values defined in the parent data label collection. |
| [get_Font](./get_font/)() | Provides access to the font formatting of this data label. |
| [get_Format](./get_format/)() | Provides access to fill and line formatting of the data label. |
| [get_Index](./get_index/)() | Specifies the index of the containing element. This index shall determine which of the parent's children collection this element applies to. Default value is 0. |
| [get_IsHidden](./get_ishidden/)() | Gets/sets a flag indicating whether this label is hidden. The default value is **false**. |
| [get_IsVisible](./get_isvisible/)() | Returns **true** if this data label has something to display. |
| [get_Left](./get_left/)() | Gets or sets the distance of the data label in points from the left edge of the chart or from the position specified by its [Position](./get_position/) property, depending on the value of the [LeftMode](./get_leftmode/) property. |
| [get_LeftMode](./get_leftmode/)() | Gets or sets the interpretation mode of the [Left](./get_left/) property value: whether it sets the location of the data label from the left edge of the chart of from the position specified by its [Position](./get_position/) property. |
| [get_NumberFormat](./get_numberformat/)() | Returns number format of the parent element. |
| [get_Orientation](./get_orientation/)() | Gets or sets the orientation of the label text. |
| [get_Position](./get_position/)() | Gets or sets the position of the data label. |
| [get_Rotation](./get_rotation/)() | Gets or sets the rotation of the label in degrees. |
| [get_Separator](./get_separator/)() | Gets string separator used for the data labels on a chart. The default is a comma, except for pie charts showing only category name and percentage, when a line break shall be used instead. |
