sorry to bump this, but I cannot find the answer to this.
I have tried lots of css things, but nothing is removing this annoying line.
Woule really appreciate some help.
Yep, stumped me when I first came across it too.
You basically want to change the how the gridlines are shown, it is in live docs close to your link above but here is some code below. You can do it through MXML as below or through CSS/AS3.
<mx:LineChart id="myChart" >
<mx:GridLines direction="vertical" verticalShowOrigin="false" >
<mx:GridLines direction="horizontal" horizontalShowOrigin="false" >
<mx:LineSeries id="mySeries" />
The relevant property is verticalShowOrigin or horizontalShowOrigin.
Thanks Ian - thats perfect!
Really apprciate you taking the time to help out a stranger.
No worries, glad I could help
