Как создать диаграмму типа
http://junkcharts.typepad.com/junk_charts/2010/01/leaving-ink-traces.html
где несколько временных рядов (по одной на страну) отображаются горизонтально как симметричные области?
Я думаю, что если бы я мог отображать один временной ряд таким образом, его легко обобщить на несколько, используя mfrow.
