The axis object used to map data values to an angle between 0 and 2 PI. By default, this is a linear axis with the autoAdjust property set to false. So, data values are mapped uniformly around the chart.

A number from 0 to 1, specifying how far all wedges of the pie series should be exploded from the center of the chart as a percentage of the total radius.

This value explodes all wedges in the pie series uniformly. You can set the value for individual wedges via the perWedgeExplodeRadius property.

The explode radius for any individual wedge is the value of the explodeRadius property plus its value in the perWedgeExplodeRadius Array.

To guarantee that the pie series stays within its containing chart's bounds while pulling out wedges, the pie series might shrink the total radius of the pie. If you dynamically pull out wedges at run time, the total pie radius shrinks. To avoid this effect, you can "reserve" the space and shrink the total radius initially by setting the reserveExplodeRadius property to the maximum explode radius you intend to set at run time.

Specifies the field of the data provider that determines the data for each wedge of the PieChart control.

The default value is null.

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 fills style property. But if it returns null, then fills will be prefered.

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:PieSeriesItem = PieSeriesItem(item);
          if (curItem.number > 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.

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.

Name of a field in the data provider whose value appears as label Ignored if labelFunction is specified

Specifies a callback function used to render each label of the PieSeries. The callback function has the following format:

      function_name(data:Object, field:String, index:Number, percentValue:Number):String { ... }
      

The maximum amount of the PieSeries's radius that can be allocated to labels. This value is only applicable when the series is rendering callout labels.

When rendering callout labels, the PieSeries reduces the radius of the wedges to allow space for the labels along the sides. Once the amount of space allocated to the labels reaches this limit, the series begins reducing the size of the labels to stay within this size.

Specifies the field of the data provider that determines the name of each wedge of the PieChart control.

The default value is null.

The percentage of the total space available to the PieSeries to use when rendering the contents of the series. This value is managed by the containing chart, and should not be assigned to directly.

This value ranges from 0 to 1.

An Array of numbers from 0 to 1, specifying how far each wedge of the pie series should be exploded from the center of the chart as a percentage of the total radius.

The nth value in this Array corresponds to the nth pie wedge. For example, to pull the third wedge half way out, you assign perWedgeExplodeRadius = [ 0, 0, 50];.

null or missing values in the Array are treated as 0.

To guarantee that the pie series stays within its containing chart's bounds while pulling out wedges, the pie series might shrink the total radius of the pie.

If you dynamically pull out wedges at run time, the total pie radius shrinks. To avoid this effect, you can "reserve" the space and shrink the total radius initially by setting the reserveExplodeRadius property to the maximum explode radius you intend to set at run time.

The value for an individual wedge in the perWedgeExplodeRadius Array is added to the value of the series's explodeRadius property to calculate the total explode radius for any given wedge.

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.

A number from 0 to 1, specifying how much of the total radius of the pie series should be reserved to explode wedges at runtime. When a pie wedge is exploded, the series must shrink the total radius of the pie to make sure it doesn't exceed the bounds of its containing chart. Thus if a developer changes the explode value of a wedge at runtime, it can effectively shrink all the wedges rather than the desired effect of pulling out a single wedge. To avoid this, set reserveExplodeRadius to the maximum value you intend to explode any wedge at runtime.

Specifies the starting angle for the first slice of the PieChart control. The default value is 0, which is horizontal on the right side of the PieChart control.

Parameters

Programmatically draws the graphics for this skin.

Subclasses should override this method and include calls to methods such as graphics.moveTo() and graphics.lineTo().

This occurs before any scaling from sources such as user code or zoom effects. The component is unaware of the scaling that takes place later.
