5.0 PLOT Command
The PLOT command controls B34S line printer graphing and plotting
options. For high resolution graphics (available on PC) see HRGRAPHICS
The general form of the PLOT command is:
B34SEXEC PLOT options parameters$
VAR variable1 variable2 $
TITLE =(' ') $
The VAR sentence is required.
GRAPH - Will make a X - Y plot of two variables on one page.
This option is the default.
LPPLOT - Will 'plot' up to 9 variables where each line
represents one observation
CSCALE - Used with LPPLOT option. Sets common scale for all
variables plotted. The default is an individual
IBEGIN=n1 Sets the beginning observation. Defaults to 1.
IEND=n2 Sets end observation. Defaults to number of obs in
CHARACTER = Sets character for LPPLOT. If CHARACTER parameter
not supplied, defaults to 1 2 3 4 . Assume 4
variables. CHARACTER=(M,Y,Z,Q) sets plot characters
to M Y Z Q for first four series on the VAR command.
The VAR sentence specifies the variables to use. If LPPLOT is set
as an option, the maximum number of variables in the VAR sentence is 9.
If GRAPH is set as an option, two variable names must be supplied in the
TITLE=(' ') $
The TITLE sentence allows the user to specify a title. The length
of the title can be up to 80 characters long. It must not contain a
delimiter character ($) or the B34SEXEC or B34SEEND key words.
Examples of PLOT option.
B34SEXEC PLOT GRAPH$
TITLE=('Graph of variable X against variable Y') $
VAR X Y$
B34SEXEC PLOT LPPLOT CHARACTER=(X,Y)$
TITLE=('Plot of variable X against Y')$
VAR X Y$
Note: Most users prefer high resolution plots. The advantage of the
PLOT command is the plots are in the output stream.
