You can manually tweak it, or programmatically tweak it:

All,

I have created a combination chart which use bars to show company
financials and a line to show unit sales. During the early part of the
company's history, certain financial values are less than zero, thus
the minimum value for the primary y-axis scale is less than zero.

The problem is this - Excel aligns the minimum values of both y-axis
scales, thus zero units is aligned with negative dollars. This is
confusing to the viewer.

My question is this: Other than manually tweaking the scale for the
number of units sold, is there an automatic means for having zero be
aligned on both scales?

Thank you.
