For each axis, you can set the Scaling and
Printing of one tic. The Scaling
option selects how many units apart the axis tics will be (and therefore, how
far apart grid lines will be drawn), and the Printing
option selects the length of one tic when displayed on the screen or
printed. In this way, these options can be used to change the size of the graph
on screen or on a page: For example, doubling the Printing
setting whilst keeping the Scaling setting the same will
result in the graph doubling in in height or width.
