Dataplot: Mathematics Characters
Introduction Mathematics symbols can be generated within any TEXT, TITLE, LABEL, or LEGEND command whenever the Hershey fonts (simplex, duplex, triplex, triplex italic, complex, simplex script, and complex script) have been specified (see the FONT command).
Method for Specifying Mathematics Symbols To indicate that a mathematics symbol should appear in some text string, simply enter the abbreviated (never more than four characters) name from the list below and append an open and closed parenthesis after the name, as in INTE(), SUMM(), and DOTP(). The () is a flag to Dataplot that the previous character sub-string is not to be printed literally but rather should be converted and drawn as a special symbol.
Examples For example, go to the middle of screen, and draw out summation, integration, and infinity symbols in simplex font:
    FONT SIMPLEX
    MOVE 50 50
    TEXT SUMM()INTE()INFI()
As another example, go to the middle of screen, and write out A union B (a set theory notation) in upper case triplex font:
    CASE UPPER
    FONT TRIPLEX
    MOVE 50 50
    TEXT AUNIO()B
Table Showing the Available Mathematics Symbols The following table shows the available mathematics symbols.
    PART() partial derivative
    INTE() integral
    CINT() circular integral
    SUMM() summation
    PROD() product
    INFI() infinity
    +-() + or -
    -+() - or +
    TIME() times
    DOTP() dot product
    DEL() vector product
    DIVI() division
    LT() less than
    GT() greater than
    LTEQ() less than or equal to
    INTE() integral
    GTEQ() greater than or equal to
    NOT=() not equal
    APPR() approximately equal to
    EQUI() equivalence
    VARI() varies
    TILD() tilda
    CARA() carat
    PRIM() prime
    RADI() radical
    LRAD() large radical
    BRAD() larger radical
    SUBS() subset
    SUPE() superset
    UNSB() un-subset
    UNSP() un-superset
    UNIO() union
    INTR() intersection
    ELEM() is an element of
    THEX() there exists
    THFO() therefore
Sample Dataplot Program to Generate the Mathematics Symbols The following Dataplot program was used to generate the mathematics symbols in a duplex font.
