You have several choices for canceling SYMBOL statement options. You can cancel

• an individual option

• all options in one SYMBOL statement

• all SYMBOL statements currently in effect.

The following examples illustrate ways of canceling SYMBOL statement options.

     symbol1 interpol=join color=yellow
             width=1.5; 

. . . you could cancel only the COLOR= option by submitting the following null statement:

     symbol1 color=;

If you had originally submitted these statements . . .

     symbol1 interpol=join color=yellow width=2
             value=square; 
     symbol2 interpol=join color=blue width=2
             value=star; 

. . . you could cancel all the options in the SYMBOL2 statement by submitting the following statement:

     symbol2;

Submitting the null SYMBOL2 statement cancels the SYMBOL2 statement but does not affect higher or lower numbered SYMBOL statements.

If you had originally submitted these statements . . .

     symbol1 interpol=join color=yellow width=2
             value=square; 
     symbol2 interpol=join color=blue width=2
             value=star; 
     symbol3 interpol=join color=red width=2
             value=triangle;

. . . you could cancel all SYMBOL statements in effect by submitting the following GOPTIONS statement:

     goptions reset=symbol; 

When you cancel a SYMBOL statement option, you return the option to its default value. For instance, canceling a WIDTH= option returns the width setting to the default value of WIDTH=1.
