This chart shows how far down into a page users read on the Android Wikipedia app. (The vertical axis denotes the lowest position that became visible in the viewport, as ratio of the total page height in pixels. The horizontal axis shows the relative frequency - in pageviews - with which this or a lower position was reached, making the simplifying assumption that the users has seen all parts of the page above that lowest position reached. Based on a sample from one week in March 2016.)Data: SELECT event_maxPercentViewed, COUNT(*) AS views FROM log.MobileWikiAppPageScroll_14591606 WHERE timestamp BETWEEN '20160310' AND '20160317' GROUP BY event_maxPercentViewed ORDER BY event_maxPercentViewed
