DESCRIPTION
d.histogram displays the category-value distribution for a
user-specified raster map layer, in the form of a bar chart or a pie chart.
The display will be displayed in the active display frame on the graphics
monitor, using the colors in the raster map layer's color table. The
program determines the raster file's category value distribution by counting
cells.
NOTES
d.histogram
uses the current geographic region settings
and the current mask (if one exists).
d.histogram uses the colors in the map's color look-up table
(i.e., the map's colr or colr2 file).
d.histogram
does not erase the active frame before displaying output.
