"causes the Plot title to be drawn using twice the default character size.
The range of character sizes available and the appearance of the resulting text is determined by the underlying graphics system. The default behaviour is for all graphical elements to be drawn using the default character size supplied by this graphics system.
For a list of the graphical elements available, see the description of the Plot class.
If no graphical element is specified, (e.g.
" instead of
" ), then a
operation will affect the attribute value of all graphical elements, while a
will use just the Size(TextLab) value.
