In the special case of displaying continents, it makes no sense to hide three out of six continents. A pie chart should be able to display six or seven elements. In the attached example there is no reason to group South America (>5%) into the "others" element.

Sorry, the ticket I meant was #1118, not #804
(In ) Fixes #1543
increasing pie + vertical bar charts to show 6 elements
