The Graphical Protocol (GRAPH), on the contrary, allows you to specify single dot positioning
using X and Y coordinates (string, date, clock, scrolling string, image, etc.) and to vary the font and
alignment using two properties (Font and Alignment).
In the above-stated example the writing can be positioned anywhere using the X Y coordinates of
its point of origin (in the top left corner, if the alignment is standard).
Therefore the command to be given is the following (write at position 45,8 in font 2=medium,
binary operation=0)
