This attribute determines the character fount index used when
drawing each element of a plot. It takes a separate value for
graphical element so that, for instance, the setting
Font(title)=2 causes the title to be drawn using fount number 2.
The range of integer fount indices available and the appearance
of the resulting text is determined by the PGPLOT graphics package,
but include:
- A simple single-stroke fount (the default)
- A roman fount
- An italic fount
- A script fount
