RE: [flexcoders] How can I add a child element to an AreaSeries based on the render data?

[Ely Greenfield]

Hi Mark. createChildren() is the right place for a compnent to create 'static' children. But dynamic children...i.e. children that are created or destroyed based on some runtime information, like amount of data, size on screen, etc...need to be created elsewhere.   In general, I would reccomend custom components create/destroy dynamic children in their commitProperties() function. This is because adding/removing children usually means the component needs to be re-measured. Doing it in commitProperties means you do it before any pending measurement happens, and don't end up with unnecessary extra measurement passes.   Charts, however, don't have a natural measured size.  So the various series types create and destroy their children as necessary in their updateDisplayList() function. At that point, you can be sure your data is all up to date.   Ely.   From: flexcoders@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of Mark Sent: Thursday, September 14, 2006 8:46 AM To: flexcoders@yahoogroups.com Subject: [flexcoders] How can I add a child element to an AreaSeries based on the render data? I'm creating an AreaChart that has labels inside each area. Very few of the series will be large enough to display a label so for performance reasons I only want to add labels to those that are big enough. It seems to me that the best place to create and add the label is in createChildren(), however in examining the renderData, the filterCache is null and all the bounds values in the cache are NaN. Where would be the best place to add the label (as far as performance goes)? Thanks in advance for any help.
