I submitted this issue to the Adobe Flex Bug Mgmt System a few weeks back but haven't as yet seen a comment, nor did my last post on this forum yield a response, so I'm going to give it another go here.
The problem I'm seeing is that you cannot dynamically switch itemRenderers on a chart series at runtime. You can code it, and run it, but any and all previous itemRenderers remain active. Since your likely initial graphics command is Graphics.clear(), you may not notice the problem as each itemRenderer clears the previous itemRenderer's drawing, BUT under the covers this continued switching of itemRenderers will add itemRenderers to the priorityQueue, eating memory and slowing things down along the way. ItemRenderers are never removed from the queue. I'm hoping someone with knowledge, or at least interest, could weigh in and let me know if indeed it's a bug, or if I'm coding this incorrectly, or if there's an alternative approach, etc... I'm polishing off a 3D ColumnChart and may have to remove support for dynamic itemRenderers. More info, a screenshot of a huge priorityQueue, and sample code can be found in my bug report: https://bugs.adobe.com/jira/browse/FLEXDMV- 1882. Thanks in advance to anyone who can help me move past this issue. Cheers, Eddie
