<P>The  font style is generally controlled with the <code><a href="gradcomdsetfont.html">set font</a></code> command. To temporarily override the  font  in a string of text, use the back quote character (`). A back quote followed by a digit selects that font number for the remainder of the string. It is also possible to use the back quote to change the position of the text, to draw a string above or below the base line for subscripts or superscripts. A back quote followed by the letter a (`a) will draw the subsequent text in the string as a superscript (above normal). A back quote followed by the letter b (`b) will draw the subsequent text in the string as a subscript (below normal). A back quote followed by the letter n (`n) will draw the subsequent text in the string in a normal position, to undo the effects of `a or `b. The use of the back quote to override the font works with the draw string command, contour labels, titles, axis labels, etc.
