label

An object defining constant line label options.

Type:

Object

This object configures all the constant line labels of the value axis. A constant line label shows information on the constant line. Within the label object you can configure position, text and font options using the corresponding fields. In addition, you can specify the horizontal and vertical alignment for the label.

To configure styles for the constant line labels of the argument and value axis together, use the commonAxisSettings | constantLineStyle | label object.

In addition, you can define the appearance of each constant line label individually. For more information, refer to the valueAxis | constantLines | label object description.
