Apparently this is a bug. Excel 2007 seems to think the tiny values are
roundoff errors. Fortunately it plots the data fine, but unfortunately the
axis can't handle the values. I'll pass it along.

I am using the following data series for a scatterplot and I am not getting
any major (or minor) horizontal gridlines automatically (or manually
setting
the axis major and minor points). Any thoughts?

I'm using Office 2007

Thanks,
Ben
