)
Draws lowerFunc and upperFunc in terms of
x
on the
current graph and shades the area bounded by
lowerFunc
, upperFunc, xLeft, and xRight. The shading
style is determined by pattern (
1
through
4
) and
patternRes
(
1
through
8
).
pattern
:
1
= vertical (default)
3
= negative-slope 45
¡
2
= horizontal
4
= positive-slope 45
¡
patternRes
(resolution):
1 = every pixel (default)
5 = every 5th pixel
2 = every 2nd pixel
6 = every 6th pixel
3 = every 3rd pixel
7 = every 7th pixel
4 = every 4th pixel
8 = every 8th pixel
Shade(
lowerFunc
,
upperFunc
)
Sets xLeft and xRight to
xMin
and
xMax
, respectively,
and uses the defaults for pattern and patternRes.
