Bug-free Axis, anyone?

[V{rri Alpo]

Axis is a nice little 2D-data plotting program which we use quite a lot in
our laboratory. In our version there is, however, an annoying bug which
appears mainly, when the user forces a certain scale with the #x and #y
options. In this case Axis cannot break unconnected curves separate, but
connects them together in nasty ways. (You get the picture if you try the
included Axis code and you get a line from point (4,-44) to point (25,0).)

What I'm asking now is that if somebody has a version of Axis that does
not produce the above explained error, could this person kindly inform us
how to obtain the bug-free version.

Please respond to our system manager Pertti Lehtinen, (pl at tut.fi) or to me
(varri at tut.fi), if you cannot reach Pertti for some reason.
