layerLabels

Configure annotations for geometry layers.

Annotations are currently supported for bar, pie, and crossbar geometry layers. This class provides methods to customize the appearance and content of text labels displayed on these geometries.

Notes

By default, annotation text color is automatically selected for optimal contrast: white text appears on darker filled geometries, and black text appears on lighter filled geometries.

The text color can be manually specified using: `theme(labelText=elementText(color=...))`

Alternatively, the `inheritColor()` method can be used to override both automatic and manual color settings, making the annotation text use the geometry's `color` aesthetic instead.

Examples

• annotations_for_pie.ipynb

val data = mapOf("name" to listOf("a", "b", "c", "d", "b"), "value" to listOf(40, 90, 10, 50, 20))
letsPlot(data) +
     geomPie(
         size = 15, hole = 0.2,
         labels = layerLabels("..proppct..").format("..proppct..", "{.1f}%").size(15)
     ) { fill = asDiscrete("name", orderBy = "..count.."); weight = "value" }
