[GREG1\]HISTOGRAM [Array_X Array_Y] /FILL [Icol] [/BASE Ybase]
The /FILL option indicates to fill the histogram with the colour of the
current pen. Blanking is handled as for other histograms. Usually needs
to be done in conjunction with the BASE option to properly fill the his-
togram. Icol is the number (0-23) of the color used to fill. The colors
of the last 16 pens (8-23) can be changed by the user (See
HELP LUT /PEN).
