NAME
     AddTitle - add 2D text annotation

SYNOPSIS
     AddTitle <coord> expr string

DESCRIPTION
     Add a text annotation at a given screen position.
     The screen position must be entered by a mouse click
     or on the command line. The second argument is the
     size, the third the string to be displayed.

     The origin of the screen coordinates is at the center
     of the window. The x-axis runs from left to right,
     the y-axis from bottom to top. The range for y is
     -1.0 to 1.0, the one for x depends on the aspect
     ratio, e. g. it would be -1.5 to 1.5 if the window
     width is 50% larger than the window height.

     For an explanation on how to enter greek letters,
     sub- and superscript, see the manual page of the
     EditText command.

     The created primitives have the properties "text"
     and "title".

EXAMPLES
     AddTitle 0.5 0.3 0.15 "Label"
