An object defining the label configuration options.
Each series point can be accompanied by a text label that represents data related to the point. These are called series point labels. Use the label object's properties to set label options for the series.
Formats the point argument before it is displayed in the point label. To format the point value, use the format option.
Colors the point labels' background. The default color is inherited from the points.
This option supports the following colors:
- Hexadecimal colors
- RGB colors
- RGBA colors
- Predefined/cross-browser color names
- Predefined SVG colors
You can remove the label's background by setting this option to "none". In this case, the label's text is the same color as the point.
Specifies border options for point labels.
Use this object to make the borders of point labels visible/invisible and set up border options such as color and width.
Specifies connector options for series point labels.
A series point label can be placed separately near the represented point. To make the relationship between a label and its respective point clear, use a connector. Set the connector's visibility and appearance options using the connector object.
Specifies a callback function that returns the text to be displayed by point labels.
Information on the series point.
