Symbols
Symbols can optionally be drawn at every data point by setting
set( PLOTTYPE , SYMBOLS); or set( PLOTTYPE ,
SYM_LINES);. The actual symbol used is set using set( CURSYMBOL ,
sym_number ); Symbols are just a special font and
much of the above discussion on how to change a letter's appearance
applies also to symbols. There is, however, no complex version of the
symbols. Additionally, the size of the symbols can be adjusted relative to
the current font size using set( SYMMULT ,multiplier);. Symbols can also be drawn independent of drawdata(
); at an arbitrary location by using symbol( x , y ,
sym_number);. For an example of the symbol capabilities consult the last
example of the previous chapter. Symbols may also be included in text
strings drawn with text(); by enclosing the symbol number with '$'
in the text string.
