From: Maximilian Güntner Date: Mon, 11 Jun 2012 00:45:36 +0000 (+0200) Subject: added "Zoom" button and improved scaling X-Git-Url: http://git.tdb.fi/?a=commitdiff_plain;h=7acd075bd5ad1c6d42ba77b484aebc2a0572f710;p=ext%2Fsubsurface.git added "Zoom" button and improved scaling It should be possible to have a certain limit where we stop zooming so that short dives are visible as such at first glance. Therefore a "Zoom" button has been added to the "Log" menu along with a shortcut (Ctrl + "0"). The user can now zoom/unzoom the plot and is still able to quickly distinguish short dives from normal ones when browsing the log.
