Hi,
I had the same problems as reported by several people earlier with
non-working plotting in octave 3.4.0 in cygwin-1.7.9.
I got windows 7 - 64 bit system (with latest windows 7 service pack as of
date of writing) working with plotting and octave 3.4.0 this way:
I did:
1. Downgrade to cygwin 1.7.8 and reinstalling all cygwin packages.
2. Close all cygwin applications.
3. Open "cmd.exe"
4. cd C:\cygwin
5. Run: C:\cygwin\bin\ash.exe
6. Run: /bin/rebaseall
Then (I did no reboot) I started XWin and octave and: "plot(1:10,1:10)"
gives me a window with the plot. I have also run octave using some scripts
of mine and it works fine with both "plot" and "imagesc". Octave seems to
work in cygwin now like in Unix for me;) However, I am clueless as to why
the "fix" reported above did work.
Here is my uname -a:
CYGWIN_NT-6.1-WOW64 angmar 1.7.8(0.236/5/3) 2011-03-01 09:36 i686 Cygwin
Regards,
Eirik
