 Priority:  normal       |   Milestone:  7.0.0                    
Component:  Display      |     Version:  svn-releasebranch70      
 Keywords:  d.legend     |    Platform:  All                      
      Cpu:  Unspecified  |  
-------------------------+--------------------------------------------------
 Legend of integer (CELL) maps are shown upside-down with the
 lowest value on top. This enforces the user to always activate
 the -f flag:


 {{{
 # NC location
 g.region rast=basin_50K
 d.mon wx0
 d.rast basin_50K
 d.legend basin_50K

 # other example

 d.legend basin_50K
 r.mapcalc "elev_int = round(elevation)"
 r.colors elev_int color=srtm
 d.erase
 d.rast elev_int
 d.legend elev_int -s
 ## --> upside-down, see screenshot
 }}}

 Expected: the legend should be with the lowest value down and the
 highest up as it is for floating point maps.

 Maybe trivial to fix but I am not sure where to add a "flipit" in the
 main.c
