Why isn't my curve fit showing up?

Sometimes when I select a curve fit I get an error, or the fit curve never shows up.

For some curve fits (natural and base-10 logarithms for example) having a zero in the data causes a fatal divide by zero situation that doesn't allow the curve fit algorithm to work properly. If you deselect the zero point from the data, often the fit tool will become functional again.
