spd_ui_draw_object method: niceNumTime Function adapted from Graphics Gems: Heckbert, Paul S., Nice Numbers for Graph Labels, Graphics Gems, p. 61-63, code: p. 657-659 It identifies the closest "nice" number Nice being a number j * 10 ^ n where j = 1,2,5 and n = any integer This routine performs nicenum on a time in seconds, it will account for whether the input is closer to an hour or a minute or a day. Good factors to use with this routine are [1,2,3,6,10] Its Input/Output/Return parameter are identifcal to niceNum $LastChangedBy: jimm $ $LastChangedDate: 2014-02-11 10:54:32 -0800 (Tue, 11 Feb 2014) $ $LastChangedRevision: 14326 $ $URL: svn+ssh://thmsvn@ambrosia.ssl.berkeley.edu/repos/spdsoft/trunk/spedas/gui/display/draw_object/spd_ui_draw_object__nicenumtime.pro $
