Pies can really make you dumb. No, seriously, thank you very much Josh! Josh is right, our redesign was erroneous. Pies can really make you dumb.

The bar for Mortgage banks (41%) is less than half the size of the bar for Commercial banks (45%). The bar for Others (11%) seems ~1/8 the size of the bar for Mortgage banks, instead of ~1/4 as we expect. Did the axes get chopped? It is nice that the display is clean enough that these discrepancies jump out instead of being hidden in chartjunk.

In a management report, however, they almost never have a place. If you look at the pie charts for the German municipality, and add upp the numbers for the first pie, you will find (like is shown in your bar chart), that they add up to 4885. The pie quite clearly shows a sum of 5485! And that figure must be correct, as only then will the revenues - surplus end up as the amount of expenses (5485 - 306 = 5179). Finally, I would also in the bar charts put the "other" groups last, even though they often have large (if not the largest) figures. The other group is probably made up of a large number of small parts, which would place it last.
