PlotSeries  - AS3 Flex

Specifies a method that returns the fill for the current chart item in the series. If this property is set, the return value of the custom fill function takes precedence over the fill and fills style properties. But if it returns null, then fills and fill will be prefered in that order.

The custom fillFunction has the following signature:

     function_name (item:ChartItem, index:Number):IFill { ... }
     

An example usage of a customized fillFunction is to return a fill based on some threshold.

     public function myFillFunction(item:ChartItem, index:Number):IFill {
          var curItem:PlotSeriesItem = PlotSeriesItem(item);
          if (curItem.yNumber > 10)
              return(new SolidColor(0x123456, .75));
          else
              return(new SolidColor(0x563412, .75));
     }
     

If you specify a custom fill function for your chart series and you want to have a Legend control, you must manually create a Legend control and add LegendItems to it.

Defines the labels, tick marks, and data position for items on the x-axis. Use either the LinearAxis class or the CategoryAxis class to set the properties of the horizontalAxis as a child tag in MXML or create a LinearAxis or CategoryAxis object in ActionScript.

Gets all the items that are there in the series after filtering.

Individual series determine the list of items that are to be returned.

The subtype of ChartItem used by this series to represent individual items. Subclasses can override and return a more specialized class if they need to store additional information in the items.

A module factory is used as context for using embedded fonts and for finding the style manager that controls the styles for this component.

The subtype of ChartRenderData used by this series to store all data necessary to render. Subclasses can override and return a more specialized class if they need to store additional information for rendering.

The subtype of ChartRenderData used by this series to store all data necessary to render. Subclasses can override and return a more specialized class if they need to store additional information for rendering.

Defines the labels, tick marks, and data position for items on the y-axis. Use either the LinearAxis class or the CategoryAxis class to set the properties of the verticalAxis as a child tag in MXML or create a LinearAxis or CategoryAxis object in ActionScript.

Specifies the field of the data provider that determines the x-axis location of each data point. If null, Flex renders the data points in the order they appear in the dataProvider.

기본값: null.

Specifies the field of the data provider that determines the y-axis location of each data point. If null, the PlotSeries assumes the data provider is an Array of numbers, and uses the numbers as values.

기본값: null.

Constructor.

Customizes the item renderer instances that are used to represent the chart. This method is called automatically whenever a new item renderer is needed while the chart is being rendered. You can override this method to add your own customization as necessary.

Processes the properties set on the component. This is an advanced method that you might override when creating a subclass of UIComponent.

You do not call this method directly. Flex calls the commitProperties() method when you use the addChild() method to add a component to a container, or when you call the invalidateProperties() method of the component. Calls to the commitProperties() method occur before calls to the measure() method. This lets you set property values that might be used by the measure() method.

Some components have properties that affect the number or kinds of child objects that they need to create, or have properties that interact with each other, such as the horizontalScrollPolicy and horizontalScrollPosition properties. It is often best at startup time to process all of these properties at one time to avoid duplicating work.
