DISTR DRAW Menu
To display the
DISTR DRAW
menu, press
y = ~
.
DISTR DRAW
instructions draw various
types of density functions, shade the area specified by
lowerbound
and
upperbound
, and display the
computed area value.
Selecting an item from the DIST DRAW menu opens a wizard for the input of syntax for that item.
Some of the arguments are optional. If an argument is not optional, the cursor will not move on to
the next argument until a value is entered.
If you access any of these functions through CATALOG, the command or function will paste and
you will be required to fill in the arguments.
To clear the drawings, select
1:ClrDraw
from the
DRAW
menu (Chapter 8).
