I manually set the minimum value for zero. I did not check the autoscale
box. It seems to be an issue due to the large span of the data. If I try my
setup with data over about 500, the -1 values appear. If the data contain
points under ~500, the data disappear.
Also, this is in Excel 2003.

I have seen this behaviour before with a very large data set. It was sent to
me by a grad student years ago (I recall it had to do with birtds) and I am
trying to recall the simple solution. If it comes in my dreams, I will let
you know. Meanwhile, rest asssure it is likely not a problem with your PC or
Excel installation
If you send me the file (private email) I will have a look - but Jon is the
chart expert

Well, that's weird. I have about 25 points, with Y values ranging between 0
and almost 5000. I set the min to 0 and the max to 5000, and inserted a
small number of negative values. The points for -1 and -5 appear on the
chart, and -10 does not. It looks like the -1 and -5 points are still
centered on the axis line, and since 10 is one pixel above, -10 must be one
pixel below and therefore is considered to be "off the chart".
If I have a chance soon I'll submit this as a bug. Since it doesn't seem to
occur in Excel 2007 (based on very limited testing), it's probably not worth
submitting.

Thank you both. It's inconvenient, but I'll survive... :)

Are the data linked from somewhere else? You could change the link formula
from
=A1
to
=IF(A1<0,NA(),A1)
The NA() produces an error in the cell, but any marker-type series doesn't
plot the point.
