Re: [flexcoders] AxisRenderer Bug

Ely,

Interestingly, I went and modified one of the examples from the ChartExplorer to send to reproduce and send to you.  It's labelRotation was set to 90, and the error wouldn't reproduce.  So I changed it to 75 (which is what I had my production chart set to) and sure enough, error.  I didn't try everything > 0 and < 90, but i'd assume that's where the error occurs...  Below is a reproducable app... just drag the divider up until the label's disappear on the chart.

Thanks

Hi Brendan.  I think I actually just fixed this bug in the mainline a few days ago. If you have a simple reproducable file you could send me, I can verify it.
 
Thanks,
Ely.

Hi,

Came across something today, which I'm guessing should be filed as a
bug...

If you are using an AxisRenderer on a chart, and resize the Chart
instance to the point that the labels disappear, you get the following

Cannot access a property or method of a null object reference.at
mx.charts::AxisRenderer/adjustGutters()[C:\dev\beta3\sdk\frameworks\mx\charts\AxisRenderer.as:1182]

Brendan
