ok, if you can provide a complete example, I can check to see if the problem remains ... or you can try replacing your axis.m function with the current 3.2.x version and let us know if it works for you.

    http://hg.tw-math.de/release-3-2-x/file/d6052da689e2/scripts/plot/axis.m

Click on the "raw" link and it should download. Be sure to place it in a location where it will precede the installed axis.m (your current working directory will work).
