Re: [Graphs-users] JPlot

[Jan v. d. L. <Jan...@en...>]

David,

   That problem has been noticed before, and is addressed in version
1.3. Since this version is currently unstable, I cannot propose it yet
to anyone... But I uploaded a patched version 1.2.2 to the website:
the only differenc with 1.2.1 is that it will correctly display the
negative numbers.

Hope this helps,
=2DJan.
