Re: bizarre plotting behavior

[Matthias Brennwald]

Dear Ron et al,

I had a similar plotting problems with Octave 2.9.9. Octave 2.1.71  
(that's what I have now) does fine with the below examples. I believe  
my plotting problems are fixed in the current Octave 2.9.9 code  
available by CVS. However, I never tried this, because I am too  
stupid to compile that.

Cheers,
Matthias
