# Data Labels Annotation (X and Y-axes only)

## Content



**DataLabels** are a collection of labels that display text defined at each point along the X or Y-axes. **DataLabels** annotation cannot be used for the Z-axis.

Use the [RowLabels](/componentone/api/win/online-chart3d/dotnet-framework-api/C1.Win.C1Chart3D.4.8/C1.Win.C1Chart3D.Chart3DGroups.RowLabels.html) and [ColumnLabels](/componentone/api/win/online-chart3d/dotnet-framework-api/C1.Win.C1Chart3D.4.8/C1.Win.C1Chart3D.Chart3DGroups.ColumnLabels.html) ChartGroups properties to define and edit DataLabels. These properties can be accessed through the **Chart3DDataLabel Collection Editor**. The respective editors for RowLabels and ColumnLabels can be accessed by:

1.  Expanding the **ChartGroups** node in the Visual Studio Properties window.
2.  Clicking on the **ellipsis** adjacent to the ColumnLabels or RowLabels properties.

Set [AnnoMethod](/componentone/api/win/online-chart3d/dotnet-framework-api/C1.Win.C1Chart3D.4.8/C1.Win.C1Chart3D.Chart3DAxis.AnnoMethod.html) to **DataLabels** for an axis and use this tab to define the labels.


> type=note
> **Note**: **DataLabels** annotation can be used only for regular and irregular grid data.
