Type of data used in Axis.

_type

Unknown private

Type of data used in Data.

Attributes

labelFormat

String

Pattern used by the labelFunction to format a label.

Fires event labelFormatChange

Fires when the value for the configuration attribute labelFormat is changed. You can listen for the event using the on method if you wish to be notified before the attribute's value has changed, or using the after method if you wish to be notified after the attribute's value has changed.

Parameters:

  • e EventFacade
    An Event Facade object with the following attribute-specific properties added:
    • prevVal Any
      The value of the attribute, prior to it being set.
    • newVal Any
      The value the attribute is to be set to.
    • attrName String
      The name of the attribute being set.
    • subAttrName String
      If setting a property within the attribute's value, the name of the sub-attribute property being set.

labelFunction

Function

Method used for formatting a label. This attribute allows for the default label formatting method to overridden. The method use would need to implement the arguments below and return a String or an HTMLElement. The default implementation of the method returns a String. The output of this method will be rendered to the DOM using appendChild. If you override the labelFunction method and return an html string, you will also need to override the Axis' appendLabelFunction to accept html as a String.

val
Label to be formatted. (String)
format
STRFTime string used to format the label. (optional)

Fires event labelFunctionChange

Fires when the value for the configuration attribute labelFunction is changed. You can listen for the event using the on method if you wish to be notified before the attribute's value has changed, or using the after method if you wish to be notified after the attribute's value has changed.

Parameters:

  • e EventFacade
    An Event Facade object with the following attribute-specific properties added:
    • prevVal Any
      The value of the attribute, prior to it being set.
    • newVal Any
      The value the attribute is to be set to.
    • attrName String
      The name of the attribute being set.
    • subAttrName String
      If setting a property within the attribute's value, the name of the sub-attribute property being set.
