A scale-bar simply does not & can not work with lat/lon. Distance scale is not the same on the x and y axes. Use d.grid instead. See the help page. (there was an idea to change the units to degrees/min/sec for lat/lon scalebars a while back but it hasn't been implemented yet) > And the following error is printed in the command output: > *Traceback (most recent call last): > File > "c:\OSGeo4W\apps\grass\grass-6.4.0svn\etc\wxpython\gu > i_modules\gdialogs.py", line 416, in OnOK > > # close dialog > File "C:\GRASS6\etc\wxpython\gui_modules\mapdisp.py", > line > 785, in UpdateMap > > for img in self.GetOverlay(): > File "C:\GRASS6\etc\wxpython\gui_modules\mapdisp.py", > line > 647, in GetOverlay > > if os.path.isfile(overlay.mapfile) and > os.path.getsize(overlay.mapfile): > File "C:\GRASS6\Python25\lib\ntpath.py", line 283, in > isfile > > st = os.stat(path) > TypeError > : > coercing to Unicode: need string or buffer, NoneType found > * > > Is this a bug or is this something that would be expected? > If it's a bug I will add to the trac all that extra noise isn't nice, it should give the error and quietly go away.
