[flexcoders] Plot Chart Performance

[Frias, Roberto]

Hi there,   I am having a 1000 points plot chart and I‘ve implemented a drag point feature that lets the user move the one point up and down.  When I made the first test with 10 points it looked acceptable, but now that I have 1000 it looks pretty sluggish.   What I am doing is catching the      ChartItemEvent.ITEM_MOUSE_DOWN , MouseEvent.MOUSE_UP and MouseEvent.MOUSE_MOVE events to change dynamically the vertical value of an specific object in my dataProvider ArrayCollection.   Even worst if I want to move all the points at the same time,  the chart needs more time to render the movement of all the points because it needs to change all the vertical values of all the objects in the ArrayCollection.   Does anybody knows if there is a way to manage this task in a way so the movement on the chart doesn’t look too slow???   Thankx for the advice!!!   Regards!!!   Roberto Frias [EMAIL PROTECTED] __._,_.___ -- Flexcoders Mailing List FAQ: http://groups.yahoo.com/group/flexcoders/files/flexcodersFAQ.txt Search Archives: http://www.mail-archive.com/flexcoders%40yahoogroups.com SPONSORED LINKS Web site design development Computer software development Software design and development Macromedia flex Software development best practice YAHOO!
