LineSeries  - 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:LineSeriesItem = LineSeriesItem(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.

Specifies how to represent missing data.

Set to false to break the line at the missing value. Set to true to draw a continuous line by interpolating the missing value.

The default value is false.

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.

The class used by this series to store all data necessary to represent a line segment. Subclasses can override and return a more specialized class if they need to store additional information for rendering.

Specifies the radius, in pixels, of the chart elements for the data points. This property applies only if you specify an item renderer using the itemRenderer property. You can specify the itemRenderer in MXML or using styles.

The default value is 0.

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.

Requests the line datapoints be sorted from left to right before rendering.

By default, the LineSeries renders points from left to right. Set this property to false to render the items in the order they appear in the data provider.

The default value is true.

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, the data points are rendered in the order they appear in the data provider.

The default value is null.

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

The default value is 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.
