[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.

[flexcoders] Re: deprecated horizontalAxisRenderer
Certainly! I didn't compile this, but it should be pretty close.

[flexcoders] Re: deprecated horizontalAxisRenderer
You have to tell your AxisRenderer which axis it should render by setting the axis property. --- In flexcoders@yahoogroups.com, coder3 <[EMAIL PROTECTED]> wrote: > > > Hi All, i have flex2 code, and now shows warnings in flex 3 > > for example, > > > ::: > > > > > ::: > > > will shows warning: > > 'horizontalAxisRenderer' has been deprecated.
