FinancialViz: Non-zero-based column graphs mislead the viewer

I am no longer surprised when I see a column graph in a quarterly or annual financial report that is created to give the impression that the results shown are better than the actual numbers shown. The graph does not start the vertical axis at zero so the height of the columns is not accurately indicating the values. This can be misleading for viewers and is far too common in financial presentations today.

Here’s an example from a quarterly earnings presentation from an S&P 500 company.

It is tempting to make results look better than they really are. The problem is that in doing so with a column graph that uses a non-zero-based axis, it is deliberately misleading the viewer. Once they figure out the real story, and they always will, they start to question where else you have tried to deceive them. Now they start to doubt all the results you are showing.

You don’t need to do this. Just show the accurate column graph. Viewers will appreciate the honesty and will have more confidence in the analysis and results you are presenting.
