label

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.

Use this property to set a format for arguments when you are going to display them in series labels. For a listing of acceptable formats, refer to the format property. To learn how to set a custom text for labels so that they include an argument value of the currently represented point, refer to the customizeText property.

For general information on data formatting, refer to the Data Formatting topic.

This property's value must be an integer that indicates how many digits to show in the argument displayed in series labels. This property value is considered when labels display arguments in one of the following numeric formats: 'fixedPoint', 'exponential', 'currency'. To learn how to set a format for arguments, refer to the argumentFormat property description. To learn how to set a custom text for series labels so that they include an argument value of the currently represented point, refer to the customizeText property description.

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.

Use this object to make the borders of series labels visible/invisible and set up border options such as color and width.

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.

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 and precision (optional) properties are 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 and argumentPrecision (optional) properties are specified.
• percent
  Specifies the propotional 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 percentPrecision option if this option is set.

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.

A series label displays the value of the point that the label represents. You can apply formatting to this value by using one of the available formats.

NOTE: You can set a precision for a label value when the 'fixedPoint', 'exponential', 'currency' format is applied. Use the precision and argumentPrecision properties to do this.
