Labels is a mixin whose methods are appended onto the Series class. Labels is an interface with methods implemented +in each of the Series (Pie, Bar, etc) for label creation and label placement.

+ +

The methods implemented by the Series are:

+ +
    +

  • onCreateLabel(storeItem, item, i, display) Called each time a new label is created. +The arguments of the method are:

    + +
      +
    • storeItem The element of the store that is related to the label sprite.
      • +
    • item The item related to the label sprite. An item is an object containing the position of the shape +used to describe the visualization and also pointing to the actual shape (circle, rectangle, path, etc).
      • +
    • i The index of the element created (i.e the first created label, second created label, etc)
      • +
    • display The display type. May be false if the label is hidden
      • +
    +
    • +

  • onPlaceLabel(label, storeItem, item, i, display, animate) Called for updating the position of the label. +The arguments of the method are:

    + +
      +
    • label The sprite label.
      • +
    • storeItem The element of the store that is related to the label sprite
      • +
    • item The item related to the label sprite. An item is an object containing the position of the shape +used to describe the visualization and also pointing to the actual shape (circle, rectangle, path, etc).
      • +
    • i The index of the element to be updated (i.e. whether it is the first, second, third from the labelGroup)
      • +
    • display The display type. May be false if the label is hidden.
      • +
    • animate A boolean value to set or unset animations for the labels.
