[flexcoders] Re: deprecated horizontalAxisRenderer
You best bet is step through the function that is throwing the null
reference error. We might be working with different versions of the
charting sdk, but the problem line, line 2087 CartesianChart.as, in my
copy reads
rect.top = _computedGutters.top;
so it sounds like either rect or _computedGutters are null. I would
suspect _computedGutters more than rect. You can set a break point at
the beginning of CartesianChart.updateAxisLayout and see where it gets
nulled out. After that you might be able to deduce what is wrong with
the custom AxisRenderer you're using.
If you need any more help, feel free to ask. If you can tell us when
_computedGutters becomes null, we might be able to provide some
insight as to why.
Question for you: Was the AxisRenderer you found written for Flex 2 or 3?

thanks!!! if i use the out of box code, it works fine.
but the problem is, i use an extended AxisRenderer .as class,
http://bugs.adobe.com/jira/secure/attachment/12340/InnerAxisRenderer.as.
now
i got this run time error:
do i need to modify the class? how?

I didn't compile this, but it should be pretty close.
Also, check out the example in the documentation for AxisRenderer:

Hi All, i have flex2 code, and now shows warnings in flex 3

will shows warning:

I don't know what to do so i just change
