layer
fun layerKey(label: String, group: String? = null, index: Int? = null, alpha: Any? = null, color: Any? = null, fill: Any? = null, shape: Any? = null, size: Any? = null, width: Any? = null, height: Any? = null, linetype: Any? = null, stroke: Any? = null): Map<String, Any>
Function to configure a custom legend.
Notes
The group name specified with the group parameter can be used in the labs() and guides() functions to further customize the display of this group (e.g. change its name). In particular, items in the "manual" group will be displayed without a title unless you change it manually.
If you set the same group and label for a legend element in different layers, they will merge into one complex legend element.
