Data labels are a configurable property available in the Inspector Panel. They allow you to display contextual information—such as values, categories, or series—directly on the chart, reducing the need to rely on axes or legends.

Enable Data Labels

To enable data labels, set Show Data Label to True. This option is disabled by default for most chart types, with the exception of pie charts and their variations, where data labels are enabled automatically.

Display Pattern

Data labels support several display patterns that control how label content is arranged. These patterns correspond to the fields bound in the Data Binding tab. For more information about data binding, see the Data Binding article. For example, you can display:

• Category, Series (Value) on a single line

• Category, Series on one line with Value displayed below

• Category, Series, and Value stacked vertically from top to bottom

Value Data Label

The Value data label displays the numeric measure bound to the Values data binding slot. To show values as labels, set the Value toggle to True.

When values are displayed as data labels, you may also choose to hide the value axis by setting Show Axis to False under Value Axis. This configuration is useful when the labels themselves provide sufficient quantitative context. For more details, see the Value Axis article.

Series Name Data Label

The Series Name data label displays a chart’s secondary grouping. This is commonly used in visualizations such as grouped column charts, where multiple series are compared within each category.

To learn more about secondary groupings, see the Data Binding article or the guide on building a Grouped Column Chart.

For example, in a grouped column chart, disabling Value and enabling Series Name results in labels that identify each series directly on the chart. The Legend for this chart has been removed by disabling Show Legend under the Legend properties. For more on this, read Legend.

Category Name Data Label

The Category Name data label displays a chart’s primary grouping. This is typically the field bound to the Axis (Category) data binding slot.

For more information about primary groupings, see the Data Binding article or the guide on building a Simple Bar Chart.

In scenarios where category labels are displayed directly on the chart, you may also choose to hide the category axis. To do this, set Show Axis to False under Axis (Category) properties. For more details, see the Axis (Category) article.

On Slice Label

You can further customize data labels by changing their location. For applicable chart types, setting the label location to On Slice places the label directly on the visual element itself.

Combined with chart style options—such as color themes—this configuration can improve readability for dense or compact charts. For more information, see the Chart Styles section in the Bar Charts article.

Same Color Label

Data labels can inherit the color of their corresponding legend item by setting Same Color As Legend to True. This can help visually associate labels with their data points.

When using this option, it is recommended not to place labels On Slice, as matching colors may reduce contrast and cause labels to become difficult to read or visually disappear.

Label Font Settings

You can customize the appearance of data labels by adjusting font-related properties, including:

• Font family

• Font size

• Font color

• Font weight

• Font style (italic or normal)

These settings allow you to align data labels with your dashboard's overall design and branding.

Label with Background Image

Data labels can also include a background shape or image. To enable this feature, set Show Shape to True.

Once enabled, you can specify an image in the Shape Image property. Images can be selected from your Wyn instance, sourced online, or uploaded manually.

You can further control image placement and size using the following properties:

• Shape X-Center and Shape Y-Center to adjust positioning

• Shape X-Scale and Shape Y-Scale to control image size

This configuration is useful when labels need additional visual emphasis or background contrast.

Data Labels for Pie Charts and Their Variations

Data labels behave slightly differently for pie charts and their variations. Unlike other chart types, data labels for pie charts are enabled automatically.

Pie chart data labels share many of the same properties, such as display patterns and value formatting. However, because pie charts do not use categories and series in the same way, the Series field represents the chart’s primary—and only—grouping. For more information, see the Pie Charts article.

Value as a Percentage Label

For pie charts, value labels can be displayed in two ways:

• Value, which shows the exact numeric value represented by each slice

• Value as a Percentage, which shows the percentage contribution of each slice to the whole

Enabling Value as a Percentage is particularly useful when the goal is to communicate proportional relationships rather than exact figures.

Label Line Properties

Pie charts include additional label-specific properties for connecting lines. These include:

• Line Width, which controls the thickness of the line connecting a slice to its label

• Connecting Line Color, which allows you to define a custom color for the line

These settings help improve clarity when labels are positioned outside the slices, especially in charts with many segments.
