Odd I have been struggling with the same problem for a couple hours.... ill post back if I find a solution :'(
I was able to see the minor ticks by using the style minorTickPlacement on the AxisRenderer. As I'm doing this dynamically based on the chart display, I used:
You can simply define this in the style definition for your axis renderer. This would be more simple and elegant, as long as your ticks aren't dynamically displayed.
My only problem now: I can't see the minor tick labels. Has anyone had any luck on this?
I encounter the same problem. good luck. I find the solution.
The style of minorTickStroke of AxisRenderer is none by default. So, you have to add a stroke to it.
<mx:Stroke color="0xff0000" weight="2"/>
Hope it can help you.
