## SYNOPSIS

d.rast.leg
d.rast.leg help
d.rast.leg [-n] map=string [num_of_lines=integer]

### Flags:

-n
  omit entries with missing label

### Parameters:

map=string
  raster input map
num_of_lines=integer
  Number of lines to appear in the legend

## DESCRIPTION

d.rast.leg is a GRASS script which clears the entire screen, divides it into a main (left) and a minor (right) frames, and then displays a raster map in the main frame and the map legend in the minor frame. The main frame remains active when the program finishs.

## NOTES

If the num_of_lines parameter is not given then the legend frame will display as many lines as number of categories in the map, otherwise, it will display the first num_of_lines minus 1 categories with the rest being truncated.

The user may adjust the num_of_lines parameter or the size of graphics window to get an appropriate result.

To remove all frames when clearing the display, use "`d.erase -f`".
