Research direction
Start with the linked dodge-column reproduction in F2 3.7.7 and compare the normal grouped-column case with the case containing one much larger value. Trace how the chart computes and renders the y-axis range and identify where smaller values become the zero tick. Done means the smaller values remain visible in the reproduction without breaking the normal case.
