If HISTYP = 2 or 4, the first parameter, fill, determines the fill
pattern for the individual histogram bars.
1 <= |fill[i]| <= 10 fill with hatch pattern
11 <= |fill[i]| <= 99 fill with grey scale
If HISTYP = 1 or 3, the first parameter, fill, is ignored. To fill
the area under the histogram in this case, use the SET command to set
the value of LINTYP to 100 + the hatch pattern number or to 200 + the
dot pattern number. For example, LINTYP=107 refers to hatch pattern
number 7, while LINTYP=244 refers to a dot fill pattern of every
fourth dot both horizontally and vertically.
Additional Information on:
The first optional parameter, w, controls the widths of individual histogram bars. If w is entered, the width of the histogram bar at (x[i],y[i]) will be the normal width * w[i].
The second optional parameter, c, controls the colours of individual histogram bars. If c is entered, the colour code for the histogram bar at (x[i].y[i]) will be c[i]. 1 - white 5 - yellow 2 - red 6 - cyan 3 - green 7 - magenta 4 - blue 8 - white
