Thanks for the reply. I was really hoping the new builds would fix the problem but they didn't. Even if they had, both 3.4 and 3.5a exhibit another bug which ruins my app. Whenever I refresh the data, the chart goes into some weird loop, redrawing its axis labels over and over again which makes them flash.
Was your chart done in actionscript? I wonder why it worked for you. There is definitely a bug in there somewhere though. I never had any problems before this. --- In [email protected], Richard Rodseth <rrods...@...> wrote: > > Sorry, I missed that you'd tried 3.5a.
