I’m not a chart expert but the Flex 4 code looks like the 'axis' property is required.

I have a module which compiles OK but gets a runtime error of "Property axis is not set for this AxisRenderer" It appears to happening during creation, as a breakpoint in module creationComplete handler does not get tripped. The stack trace never references any lines in my code. There are 3 charts with a fair amount of related AS3 code for each chart, so commenting out the various charts to see which one is causing the issue is difficult. What should I be looking for to help debug this? Needless to say it runs fine in the Flex/Flash system. Paul R. Stearns Advanced Consulting Enterprises, Inc. 15280 NW 79th Ct.
