The left and right halves of this graph are completely identical, including the outlying points that deviate from the trend. The irregularities in the point spacing along the X-axis (time) matching so precisely is more confirmation that this is really one set of observations made to look like two sets. This is misleading and should be captioned accordingly, or replaced with real data. — Preceding unsigned comment was added by 12.129.64.197 (talk) 21:41, 9 March 2021 (UTC)[reply]
