## NAME

d.rast.leg

## 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 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.

The user may specify a second raster map with the rast 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 rast=landclass96 -p
    d.rast.leg landclass96
