API: Accept negative value for layout keyword in plot · Issue #8071 · pandas-dev/pandas (original) (raw)

Once #7736 is merged, we can add this option

df.plot(subplots=True, layout=(4, -1)

This will behave similar to numpy's reshape method, except that we won't require the number of subplots generated by layout to exactly match the number of subplots in df. We'll just fill in the smallest integer that' sable to hold the subplots.
