Interfacepublic interface IStackable

The IStackable interface is implemented by any series that can be stacked. Stacking sets (ColumnSet, BarSet, AreaSet) require that any sub-series assigned to it when stacking implement this interface.

public function stack(stackedXValueDictionary:Dictionary, previousElement:IStackable):Number

Stacks the series. Normally, a series implements the updateData() method to load its data out of the data provider. But a stacking series performs special operations because its values are not necessarily stored in its data provider. Its values are whatever is stored in its data provider, summed with the values that are loaded by the object it stacks on top of.

A custom stacking series should implement the stack() method by loading its data out of its data provider, adding it to the base values stored in the dictionary to get the real values it should render with, and replacing the values in the dictionary with its new, summed values.

Parâmetros

stackedXValueDictionary:Dictionary — Contains the base values that the series should stack on top of. The keys in the dictionary are the y values, and the values are the x values.
 
previousElement:IStackable — The previous element in the stack. If, for exemplo, the element is of the same type, you can use access to this property to avoid duplicate effort when rendering.

Retorna
Number — The maximum value in the newly stacked series.
