DESCRIPTION


d.rast.leg shows a raster map along with its legend. It first clears the entire screen,
then divides it into a main (left) and a minor (right) frames, and displays a raster map
in the main frame and the map legend in the minor frame. The main frame remains active
when the program finishes.

NOTES


The legend may be flipped with the -f flag.

If the 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 lines minus 1
categories with the rest being truncated.

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

The user may specify a second raster map with the raster parameter from which the legend
is generated. This is useful to visualize (time) series of raster maps with a common
static legend instead of the default dynamic legend.

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

EXAMPLE


In this example, the polar diagram of the ’aspect’ angle map in the North Carolina sample
dataset location is generated:
g.region raster=landclass96 -p
d.rast.leg landclass96
