\linewidthscaling in the latter part, while there's a fixed width scaling used in the former part. If you want a figure's contents to straddle the text margins, then might be interested in Center figure that is wider than\textwidth. The suggestion is to place the contents in a\makebox[\textwidth]{...}(which will automatically center it horizontally). – Werner Jun 13 '14 at 16:40
