Excel charts: Making the scale values a reference

[Aeyyyyyy]

Is it possible to make the minimum and maximum scale values for a chart a reference to some sheet?

For example, when I click "Format Axis...", I'd like to be able to do something like type in "=Sheet1!A5" in the Minimum field, or do something that accomplishes the same thing. I could go the long way and make the chart update with a macro for certain change events, but it would be much nicer if this could somehow be worked in simply.

Any ideas?

Aeyyyyyy!
