I cannot reproduce this with the default FLTK plotting engine with the 3.8.0 release on Windows XP. The saved plots match the on-screen figures every time.

Please test the latest release to see if this still occurs.

I can confirm that the bug is still occurring on Windows with 3.6. Attached is a plot produced with the same program below using 3.6.

Octave 3.6.0 was just released. Could you verify that the problem still exists on the most recent version of Octave? Instructions for Windows platforms are here (http://www.octave.org/wiki/index.php?title=Octave_for_Windows)

Incidentally, the bug is not reproducible on a Linux platform so this may be specific to Windows.

Running the attached script with the attached data produces some strange plots to be printed. (Examples of those plots also attached.)

Steps:
1. Download the attached "bug.m" and "bugdata" files
2. In Octave, navigate to the folder containing those two files.
3. Type "bug" in octave.
4. --> Two incorrect .png files will be created
5. Type "bug" again.
6. --> Two incorrect .png files will be created (but different files than the previous ones).
7. Repeat steps 5-6 many times.
8. --> Octave crashes.

Other information:
This does not occur when running Octave 3.2.4 on my Linux box.
The plots visible in the windows Octave opens look correct.
This seems to happen with formats other than .png as well. (I tried PDF, SVG, JPG)
