Radar charts


LinearGradient as areaFill


[peeps147 said:]
Hi all,
I am trying to set the areaFill for my RadarLineSeries to a LinearGradient but keep getting the following error:
TypeError: Error #1009: Cannot access a property or method of a null object reference.
at mx.graphics::LinearGradient/begin()[E:\dev\3.1.0\frameworks\projects\framework\src\mx\graphics\LinearGradient.as:194]

at mx.core::UIComponent/callLaterDispatcher()[E:\dev\3.1.0\frameworks\projects\framework\src\mx\core\UIComponent.as:8508]
My code for the series is defined as follows:
<ilog:RadarLineSeries id="score" dataField="value" displayName="score" fillFunction="myFillFunction">
<ilog:areaFill>
<mx:LinearGradient angle="180" id="lg">
<mx:entries>
<mx:GradientEntry color="0xC5C551" ratio="0.00" alpha="0.5"/>
<mx:GradientEntry color="0xFEFE24" ratio="0.33" alpha="0.5"/>
<mx:GradientEntry color="0xECEC21" ratio="0.66" alpha="0.5"/>
</mx:entries>
</mx:LinearGradient>
</ilog:areaFill>
</ilog:RadarLineSeries>
If I try specifying the areaFill as a SolidColor it works fine. I have also tried using LinearGradient fills for series fills in other charts and it works fine as well. Any suggestions as to what might be causing this or how to fix it?? Thanks!!

Hi,
This is a bug and there is no workaround. The problem comes from RadarLineRenderer which badly uses 'areaFill' style property of RadarLineSeries class.
I've registered it at http://elixir-bugs.ilog.com/browse/ELIXIR-497.
Thanks for your interest in ILOG Elixir,
