This is not a chart of a "cycle" it is a chart of aggregate GDP. It should not be labeled or represented as the chart of a "cycle". You would need a source for that assertion. Please relabel or delete this. 24.151.107.166 00:32, 24 January 2016 (UTC)

A business cycle is rGDP. Abel (對話) 15:20, 26 January 2016 (UTC)

No, you are mistaken. Cycle is a periodic upward and downward change, either around the origin or around a trend. You can confirm this by consulting any definition or discussion of "business cycle" in an econcomics text or encyclopedia. "rGDP" is simply national income, the sum of all output in the economy, it does not relate to growth, contraction, or cycles. Please relabel this graph, so that it does not mislead the public.
