This chart appeared to today in Dutch newspaper NRC Handelsblad, showing the revenues of soccer team Ajax Amsterdam:

There is lot wrong with it in my opinion:
- Mixing cumulative and non-cumulative
- A missing final total that leaves the chart “dangling” at the end
- The typography of the horizontal axis (the matches above the columns are actually much better to use as the x-axis)
- Than the “extra” bit at the end which makes a comparison to revenues over the past 10 years
