Sets scientific notation display mode.
Selects one or more specific data points from a scatter plot
or xyLine plot (only), and then store•s the selected data
points to two new lists, Xlistname and Ylistname.
Sends contents of variable to the CBL 2™ or CBR™
System.
Returns list created by evaluating expression with regard to
variable, from begin to end by increment.
Sets sequence graphing mode.
Sets mode to graph functions sequentially.
Sets the date using a year, month, day format. The year
must be 4 digits; month and day can be 1 or 2 digit.
Sets the date format.
1 = M/D/Y
2 = D/M/Y
3 = Y/M/D
Sets the time using an hour, minute, second format. The
hour must be in 24 hour format, in which 13 = 1 p.m.
Sets the time format.
12 = 12 hour format
24 = 24 hour format
Removes all list names from the stat list editor, and then
restores list names L1 through L6 to columns 1 through 6.
Removes all list names from the stat list editor, then sets it
up to display one or more listnames in the specified order,
starting with column 1.
Draws lowerfunc and upperfunc in terms of X on the current
graph and uses pattern and patres to shade the area
bounded by lowerfunc, upperfunc, Xleft, and Xright.
