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 map’s category value distribution by
counting cells.
NOTES
d.histogram respects 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).
