Nice to see it'll be used by someone else :-)

I'm forwarding to the octave maintainer mailing list as I think this 
problem exists in any octave
version. Looking at the code, this seems to be caused by the precision 4 
used to output data
for plotting (ls-oct-ascii.cc: save_ascii_data_for_plotting). Note that 
the graphics part of octave
is in major rework for the moment and the CVS (on which my pre-compiled 
package is based)
is not really expected to work OK.

Thanks for the link. It looks interesting.

No sorry. I had the idea to convert the octave documentation to CHM and 
use the
regular help viewer of Windows: this is theoretically possible as .texi 
files can be converted
into docbook and that there exist a CHM stylesheet in recent docbook 
releases. However,
I couldn't make it work yet, there seems to be lots of errors in the 
docbook generated by
makeinfo (or I'm using incompatible packages, but I don't think so).
