backgroundColor
Specifies a background color for point labels.
Labels are painted in the color of the series points they represent by default. You can set a custom background color. For this purpose, use the backgroundColor property of the label object.
border
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.
connector
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.
customizeText
Specifies a callback function that returns the text to be displayed by point labels.
When implementing a callback function for this property, use the point value to be displayed in a label. In addition, you can use the argument of the currently displayed value. These values can be accessed using the following properties of the this object.
- value
Specifies the value of the currently represented point. - valueText
Specifies the value of the currently represented point with applied formatting if the format property is specified. - argument
Specifies the argument value of the currently represented point. - argumentText
Specifies the argument value of the currently represented point with applied formatting if the argumentFormat property is specified. - percent
Specifies the proportional value of the currently represented point in a floating point format. - percentText
Specifies the value of the currently represented point as a percentage with a precision of the format | percentPrecision option. - point.tag
Specifies the tag of the currently represented point.
The function's parameter represents the same object as the this object. If appropriate, you can use the function's parameter to obtain the value that is currently represented by a label.
