RE: [Nagios-devel] More Nagios bugs (minor)

Good day,
Thanks for your reply.
I realize that there are other ways of making the graphs- in fact, once all
our hosts are entered, using custom co-ordinates is probably going to be the
only manageable way.
Nevertheless, there is definately a bug with how the circular graph is made,
and thus it should be fixed, or at the very least examined. I don't feel
that dismissing the problem without even looking at it is a very good way to
code (although this is just my opinion).
I don't know if it's a problem with the underlying grapher, or a problem
with how data is fed to it. I'm not a very experienced C coder; if I was, I
would try to fix it myself and submit a patch. The best I can do is provide
enough detail for one of the contributers to reproduce the problem, which I
have done.
Thanks in advance to anyone who can take a look at this,
