labels looks so bad on OS X

On windows, plot labels looks good, but on OS X labels looks so bad.

Which MATLAB version are you using, and which OS-X version are you using? Are you specifying any particular font or font size for your labels?

I'm using MatlabR2011a, OS Mountain lion and labels font is default. When i plot anything, i should change the size font. But in toolbox graphics i can't change it

MATLAB R2011a is not supported on Mountain Lion.

Actually no versions are supported on Mountain Lion yet, but R2012b should "mostly work"; R2011a has no guarantees at all.
