I'm using several different chart types, including line and
histographs. Setting the minimum to 1910 would exclude data points
before that year. Admittedly, there are only a few of them, but for the
sake of completeness, it would be preferable to include them.

I'm thinking this is a limitation of Excel 2000. Is there a plug-in
(add-in? add-on?) that I can download to correct this?
