DESCRIPTION

d.barscale displays a barscale on the graphics monitor at the given screen coordinates. If no coordinates are given it will draw the barscale in the bottom left of the display.
The barscale can drawn in a number of styles (see style parameter for their previews).

NOTE

d.barscale will not work in Lat/Lon locations as the horizontal scale distance changes with latitude. Try d.grid instead.
