Hi Eddie, Thanks for the link.
I tried to emulate the example as you have provided in the link but it seems that when I set the following: <mx:ColumnSet type="stacked"> for my column series, the columns does not render (not displaying). Changing the type from "stacked" to "clustered", the columns are rendered and displayed. I still cannot figure this out though. I think it must be because both line series is intersecting with the columns, but when I tried to disable one of the line series and set the columns type to stacked, they still don't render. Am already banging my head for the past couple of days on this. I hope adobe could post a resolution on this, or perhaps a little work around. Thanks and regards, Angelo ________________________________ From: EddieBerman <[email protected]> To: [email protected] Sent: Monday, 12 October, 2009 0:35:08 Subject: [flexcoders] Re: ColumnChart & LineSeries Bug? I began creating an example for you and unfortunately discovered another bug further down the chain that had to do with stacking the columns. Rather than diagnose that now, here's a great blog article I found a while back that may be a better starting point, particularly since you'll get past the other annoying flex bug that messes with the visual spacing between columns when combining lines and columns. http://flexxxed. wordpress. com/2009/ 05/20/using- right-chart- when-you- have-multiple- chart-series/ And just an FYI - I've run into so many bugs changing from clustered to stacked to 100% at runtime that I ultimately chose to simply have multiple charts, one of each type, that I hide/show as needed. It's a headache, but since the bugs I've logged in the Adobe bug base haven't yet been addressed, it's the best solution for us. You may be luckier depending on your needs. -Eddie B. http://www.edberman .com --- In flexcod...@yahoogro ups.com, Angelo Anolin <angelo_anolin@ ...> wrote: > > Hi Eddie, > > Thanks for the pointers.
