Hi Eddie, Thanks for the pointers. Care to show some sample code on how I may be able to achieve extending the ColumnChart.as? I am quite new with Flex and would appreciate a lot if you could provide me some further directions to achieve this.
Thanks a lot.

It's a flex bug. It fails in applySeriesSet( ) in ColumnChart. as. The case statement for "stacked" and "100%" assumes that the series is a column series and chokes on the line: seriesSet[i] .offset = 0; as there's no offset for lines series. You can get past this problem by extending ColumnChart. as and overriding this function, filtering for line series. -Eddie B. --- In flexcod...@yahoogro ups.com, Angelo Anolin <angelo_anolin@ ...> wrote: > > Hi FlexCoders, > > I wonder if any of you came up with this bug in ColumnChart. > > In my ColumnChart, I have the following MXML: > > <ComboBox dataProvider= "{['overlaid' ,'clustered' ,'stacked' ,'100%']} " > id="stackType" selectedItem= "clustered" /> > > <ColumnChart id="myChart2" type="{stackType. value}" showDataTips= "true" > dataProvider= "{SMITH}" height="100% " width="100%" > > <horizontalAxis> > <CategoryAxis categoryField= "qtr"/> > </horizontalAxis> > <verticalAxis > > <LinearAxis minimum="0" maximum="3" title="YTD TRCFs"/> > </verticalAxis> > <series > > <ColumnSeries dataProvider= "{SMITH}" xField="qtr" yField="lti" > displayName= "SMITH"> > </ColumnSeries> > > <ColumnSeries dataProvider= "{SMITH}" xField="qtr" yField="rwc" > displayName= "RWC" > > </ColumnSeries> > > <ColumnSeries dataProvider= "{SMITH}" xField="qtr" yField="mtc" > displayName= "MTC" > > </ColumnSeries> > > <!--<LineSeries dataProvider= "{SMITH}" xField="qtr" > yField="target" displayName= "TARGET" > > </LineSeries> > > <LineSeries dataProvider= "{SMITH}" xField="qtr" yField="ytdTRCF" > displayName= "YTD TRCF"> > </LineSeries> --> > </series> > </ColumnChart> > <Legend dataProvider= "{myChart2} " direction="horizont al"/> > > and in my script, I have the following declaration: > > [Bindable] > public var SMITH:Array = [ > {qtr:"Jan", close:1, target:0.9, ytdTRCF:0.00, lti:0, mtc:0, > rwc:0}, > {qtr:"Feb", close:1, target:0.9, ytdTRCF:0.44, lti:1, mtc:0, > rwc:1}, > {qtr:"Mar", close:1, target:0.9, ytdTRCF:0.42, lti:1, mtc:0, > rwc:0}, > {qtr:"Apr", close:1, target:0.9, ytdTRCF:0.40, lti:1, mtc:0, > rwc:0}, > {qtr:"May", close:1, target:0.9, ytdTRCF:0.40, lti:0, mtc:1, > rwc:0}, > {qtr:"Jun", close:1, target:0.9, ytdTRCF:0.38, lti:0, mtc:1, > rwc:0}, > {qtr:"Jul", close:1, target:0.9, ytdTRCF:0.32, lti:0, mtc:0, > rwc:0}, > {qtr:"Aug", close:1, target:0.9, ytdTRCF:0.32, lti:0, mtc:1, > rwc:0}, > {qtr:"Sep", close:1, target:0.9, ytdTRCF:0.32, lti:0, mtc:2, > rwc:0}, > {qtr:"Oct", close:1, target:0.9, ytdTRCF:0.00, lti:0, mtc:0, > rwc:0}, > {qtr:"Nov", close:1, target:0.9, ytdTRCF:0.00, lti:0, mtc:0, > rwc:0}, > {qtr:"Dec", close:1, target:0.9, ytdTRCF:0.00, lti:0, mtc:0, > rwc:0} > ]; > > As you may notice, I have commented out the LineSeries tags for the column > chart component.
